In the binary case APN functions are important for constructions of S-boxes in cryptography. Similarly, a perfect nonlinear (PN) function is defined by the property that f(x+a) + f(x) is a permutation of the field for any nonzero a. PN functions have received a lot of attention in recent years, in particular in the constructions of new semifields. In this talk we will study optimal cyclic ternary sequences with parameters [3m-1,3m-1-2m,4]. Let C(1,e) denote the ternary cyclic code with generator polynomial g(x)=m1(x)me(x) where mi(x) denotes the minimum polynomial of αi where α is a primitive element of GF(pm). In 2005 Ding, Carlet and Yuan showed that if xe is a monomial PN function then the code C(1,e) has parameters [3m-1,3m-1-2m,4]. This talk will discuss generalizations of this result to cases where the monomial xe is APN as well as to other cases. In addition we give an overview of known results of values of e that give optimal codes C(1,e) with parameters [3m-1,3m-1-2m,4] and discuss the solution of an open conjecture. Finally we provide a list of open problems of possible values of e that may also give optimal codes with these parameters.

We then present a challenging problem of channel estimation for amplify-and-forward cooperative relay based orthogonal frequency division multiplexing (OFDM) systems in the presence of sparse underwater acoustic channels and of the correlative non-Gaussian noise. We exploit the sparse structure of the channel impulse response toimprove the performance of the channel estimation algorithm, due to the reduced number of taps to be estimated. The resulting novel algorithm initially estimates the overall sparse channel taps from the source to the destination as well as their locations using the matching pursuit (MP) approach. The correlated non-Gaussian effective noise is modeled as a Gaussian mixture. Based on the Gaussian mixture model, an efficient and low complexity algorithm is developed based on the combinations of the MP and the space-alternating generalized expectation-maximization (SAGE) technique, to improve the estimates of the channel taps and their location as well as the noise distribution parameters in an iterative way. Computer simulations show that underwater acoustic (UWA) channel is estimated very effectively and the proposed algorithm has excellent symbol error rate and channel estimation performance.

Vincent Poor School of Engineering and Applied Science., Princeton University, USA poor@Princeton.EDU, http://www.princeton.edu/poor Abstract: Smart grid refers to the imposition of an advanced cyber layer atop the physical layer of the electricity grid in order to improve the efficiency and lower the cost of power use and distribution, and to allow for the effective integration of renewable energy sources and distributed storage into the grid. This cyber-physical setting motivates the application of many techniques from the information sciences to problems arising in the electricity grid, and considerable research effort has been devoted to such application in recent years. This talk will focus on one such aspect, namely the tradeoff between privacy of smart grid data and the usefulness of that data, and in particular will examine via examples the roles of information theory, control theory and game theory in approaching this issue.

In fact, WPT is now considered by many as a promising new technology that may make the distributed nodes of short range wireless networks independent of external energy sources. In this talk, we will focus on two central aspects of WPT systems: 1) The impact of the energy storage capability of the energy harvesting node on the communication performance; and 2) The impact of the non-linear characteristic of energy harvesting circuits on resource allocation. In addition, we will elaborate on the challenges that have to be overcome to make WPT practical and suggest some topics for future research.

A Revisit to Cross-layer Design Philosophy Yuguang “Michael” Fang Department of Electrical and Computer Engineering, University of Florida fang@ece.ufl.edu, http://www.fang.ece.ufl.edu/ Cross-layer design in wireless networks used to be a hot topic a few years due to the fact that the traditional layering network protocol suite such as TCP/IP for wired networks are no longer efficient in wireless networks, particularly true for multi-hop wireless networks. Although there are many papers on cross-layer design, few of them really touch upon the essence of the cross-layer design, and most of them still cross physical layer and link layer for one-hop transmissions and do not reveal the real layering coupling of multiple layers. There are indeed a few papers that formulate the cross-layer design as an optimization problem and attempt to optimize all layers. Unfortunately, most optimization problems are either too difficult to solve or too idealistic to come up with practical effective cross-layer solution. In this talk, we will present a novel approach to cross-layer design: boosting the network performance while keeping the implementation practical. This approach attempt to use the MAC layer as the anchor and extract/abstract the information on the channel environment using certain novel metrics (such as the channel busyness ratio) and then tie these parameters to higher layer performance optimization. We emphasize that the cross-layer design philosophy must be done in the end-to-end perspective as what users care most is the end-to-end quality of service experience. Speaker’s Biography Yuguang "Michael" Fang (IEEE Fellow) received an MS degree from Qufu Normal University, Shandong, China in 1987, a Ph.D degree from Case Western Reserve University in 1994 and a Ph.D. degree from Boston University in 1997.

Yeung Institute of Network Coding & Dept of Information Engineering, The Chinese University of Hong Kong whyeung@ie.cuhk.edu.hk, https://www.ie.cuhk.edu.hk/people/raymond.shtml Abstract: In a network, a node is said to incur a delay if its encoding of each transmitted symbol involves only its received symbols obtained before the time slot in which the transmitted symbol is sent (hence the transmitted symbol sent in a time slot cannot depend on the received symbol obtained in the same time slot). A node is said to incur no delay if its received symbol obtained in a time slot is available for encoding its transmitted symbol sent in the same time slot. Under the classical model, every node in a discrete memoryless network (DMN) incurs a unit delay, and the capacity region of the DMN satisfies the well-known cut-set outer bound. We propose a generalized model for the DMN where some nodes may incur no delay. Under our generalized model, we obtain a new cut-set outer bound, which is proved to be tight for some two-node DMN. In addition, we establish under the generalized model another cut-set outer bound on the positive-delay region – the set of achievable rate tuples under the constraint that every node incurs a delay. We use the cut-set bound on the positive-delay region to show that for some two-node DMN under the generalized model, the positive-delay region is strictly smaller than the capacity region.

However, originally designed for the static indoor applications, the performance of IEEE 802.11 in the outdoor vehicular environment is still unclear especially when a large number of fast-moving users transmitting simultaneously. In this talk, we first introduce the Vehicular Communications Networks (VANET), its applications and design issues. We then discuss on the throughput performance of medium access control (MAC) in drive-thru Internet scenario. Due to the high mobility and transient connectivity of vehicles, we show that the DCF MAC should be adaptively adjusted according to the vehicle velocities for improving throughput performance. In addition, we will present VeMAC, a novel networking protocol designed to support advanced road safety applications via wireless communications among vehicles driving nearby each other, or among vehicles and especially deployed road-side units. The presentation includes videos of computer simulations, Lab experiments, and on-road demonstrations using real vehicles, which are conducted to highlight the efficiency of VeMAC and its potential to enhance the safety standards of future cars.

Unfortunately, orthogonality amongst user signals in existing CHMA schemes can be preserved only in synchronous channels under an assumption that neither multipath interference (MI) nor multiple access interference (MAI) exists. Exploiting their ideal orthogonality, we apply orthogonal complementary codes to CHMA systems to overcome the problems with existing CHMA schemes. In particular, we will show that the application of orthogonal complementary codes can significantly improve the performance of a CHMA system due to its unique collision resistant capability. The properties and BER performance of the proposed system are analyzed for both uplink and downlink applications, where the system may suffer MI and MAI simultaneously. Simulation results show that the complementary coded CHMA with channel coding can provide a high capacity and a robust performance.

Also, the available energy, in particular for battery operated user equipments (UEs), is limited. Therefore, the energy-efficiency will be an important concern for the next generation 5th generation (5G) mobile communications. To improve both the spectrum-efficiency and energy-efficiency, networks need to be significantly restructured. One promising solution is to introduce small-cell structure into wireless networks. However, wide range of user mobility is problematic and causes frequent handover. Furthermore, traffic density is not necessarily high everywhere. Recently, heterogeneous network (HetNet) is attracting much interest for 5G. In HetNet, a number of small base stations (SBSs) are deployed in a macro BS (MBS). Decentralized management of limited radio resources is attractive to achieve flexible deployment of small cells and higher scalability of HetNets. In this presentation, we introduce decentralized SBS power on/off and decentralized dynamic channel assignment and their impacts on network power consumption, throughput, and handover (HO).

Karagiannidiis Aristotle Univ of Thessaloniki, Greece, and ECE Dept., Khalifa Univ, UAE geokarag@auth.gr, http://geokarag.webpages.auth.gr/ Abstract: Integrating hybrid robots and communications applications is a major challenge for both robotics and Comms research & development and a key enabler for a range of advanced services and facilities. Drones (flying robots) have become a viable sensor platform, due to the advances in communication, computation, and energy storage technology, as well as the development in aerodynamic materials. So far, research has focused only on the use of drones in cases of emergency and coverage of remote locations, as well as in cases of environmental incidents and disasters. This talk will present preliminary results of our research on using drones as an economically and operationally efficient alternative for the extension of the current telecommunication infrastructure, in order to meet the future communication needs. Particularly, drones could act as micro Base Stations in order to achieve cell offloading and capacity increase, enabling the service for large numbers of users and devices. The main challenges of regular application of drones for communication purposes are: i) establishment of communication with the backbone, ii) energy sustainability, iii) compatibility with the existing network, iv) QoS awareness. To this end, a free space optical scheme is proposed for the communication in the backhaul, as well as the power supply for the drones. Also, in order to preserve compatibility, it is assumed that the drones use OFDMA to communicate with multiple users and devices simultaneously, utilizing the radio frequency band. Furthermore, a minimum rate maximization problem is formulated and efficiently solved by an iterative resource allocation algorithm. The talk will also present potential research directions and opportunities in this field. Speaker’s short biography George K.

Associated with each channel C, there is a capacity RC. There is a subset S of V. The nodes of S are called source nodes. Associated with each source node there is a collection of sink nodes. Messages are sent from source nodes. The message sent from a source node should be decoded eventually at all sink nodes associated with it. Each internal node receives messages from its parent nodes, encodes them under the channel capacity constraints and sends to its child nodes. A sink node decodes the source messages from sources associated with it based on messages it receives. The message rates of all sources is a rate vector, it is achievable if there exists a coding system that achieves it. In this talk, our concern is the determination of the capacity region consisting of all achievable rate vectors. We will show that the capacity region of network coding problem and the entropy function problem are closely related.

Non-orthogonal multiple access (NOMA) has recently received considerable attention as a promising candidate for 5G multiple access. The key idea of NOMA is to exploit the power domain for multiple access, which means multiple users can be served concurrently at the same time, frequency, and spreading code. Instead of using water-filling power allocation strategies, NOMA allocates more power to the users with poorer channel conditions, with the aim to facilitate a balanced tradeoff between system throughput and user fairness. Recent industrial demonstrations show that the use of NOMA can significantly improve the spectral efficiency of mobile networks. Because of such a superior performance, NOMA has been also recently proposed for downlink scenarios in 3rd generation partnership project long-term evolution (3GPP-LTE) systems, and the considering technique was termed multiuser superposition transmission (MUST). In this talk, we will provide a progress review for NOMA, including an information theoretic perspective of NOMA, the interaction between cognitive radio and NOMA, MIMO and cooperative NOMA.

The objective is to strategically select the sensing time such that the long-term time-average sensing performance is optimized. In the sensing system, it is assumed that the sensing performance depends on the time durations between two consecutive sensing epochs. Example applications include reconstructing a wide-sense stationary random process by using discrete-time samples collected by a sensor. We consider both scenarios where the battery size is infinite and finite, assuming the energy harvesting process is a Poisson random process. We first study the infinite battery case and identify a performance limit on the long-term time average sensing performance of the system. Motivated by the structure of the performance limit, we propose a best-effort uniform sensing policy, and prove that it achieves the limit asymptotically, thus it is optimal. We then study the finite battery case, and propose an energy-aware adaptive sensing scheduling policy. The policy dynamically chooses the next sensing epoch based on the battery level at the current sensing epoch. We show that as the battery size increases, the sensing performance under the adaptive sensing policy asymptotically converges to the limit achievable by the system with infinite battery, thus it is asymptotically optimal. The convergence rate is also analytically characterized.
