Description of work: The innovative elements of the networking architecture of MobileMAN consist of the MAC, Routing and Location components. At service level the main components is the security one. The work to be done regarding these components includes all the phases of the HW/SW development lifecycle, from requirements analysis to testing (verification testing). T3.1 Bursty-responsive MAC Develop new MAC protocol and hardware supporting bursty communication. The hardware will be based, wherever possible, on a off-theshelf 802.11 chipset whit ad-hoc programmed firmware.

(input to D11, D14) Cambridge Agenda - MobileMAN meeting (Helsinki, 8 June, 2004) WP 4 Description of work: Given the high challenges of this WP, the main tasks to be performed in it (integration and acceptance) will be addressed at two different area scales: campus-wide area scale (T4 .2 and T4 .3) and large area scale (T4 .4 and T4 .5). T4 .1 Small Area Scale Integration: Integrate part of the HW/SW developed (reduced networking and services capabilities), and install it in each node in a small and test this system in order to identify HW or simple networking problems and integration errors. Fix problems/errors found verifying that the system operates correctly.

The latter will be performed by measuring the acceptance -- from Virtual Communities (VCs) of users -of the MobileMAN system when running some simple application(s). This will task will also monitor the social construction and human behaviour of the VCs. (input to D8 - month 22), (D17 - month 34 ) All T4.3 Evaluation of MobileMAN Networking: Simulative study of the integration of MobileMAN Networking components with other relevant elements as the connection to Internet, as well as congestion control and error recovery mechanisms to optimise the utilization of the resources. (input to D16 - month 34) HUT, CNR, Eurecom Agenda - MobileMAN meeting (Helsinki, 8 June, 2004) II Year Activities • The objectives reported below are the detailed criteria for evaluating the success of the second year of the project. MobileMAN architecture implementation (CNR) - Implementation and validation of the MobileMAN architecture as defined during the first year (see D5) considering both the original and the new reference model. New applications and services (Netikos) - Adaptation of existing applications (or classes of applications) identified, during the first year, as ones that can become a customer advantage, when run on top of MobileMAN, compared to traditional technologies. Middleware (Cambridge) - Adaptation of Pastry middleware for the MobileMAN environment to exploit cross layering. - Development of new solutions for P2P information delivery based on Pastry. Co-operation Model (Eurecom) - Implementation and validation of the cooperation models and mechanisms defined during the first year. Agenda - MobileMAN meeting (Helsinki, 8 June, 2004) II Year Activities (cont.) Networking services (CNR, HUT) - Include the cross-layering view at network/transport layer - Design of packet forwarding schemes suitable for MobileMAN. - Implementation and validation of location scheme defined during the first year. - Development and testing of a complete ad hoc network Wireless Technologies (SUPSI - DIE) - Include the cross-layering view at datalink layer. - Design and implement a full datalink layer that includes the enhanced MAC protocol for ad hoc networks as designed during the first year. Socio-economic Model (SUPSI - DLS) - Apply the developed methodology for evaluating social, anthropological, and economic potential of MobileMAN, and provide the results for improving the technical parts. Agenda - MobileMAN meeting (Helsinki, 8 June, 2004) II Year Success Criteria The goals for evaluating the success of the second year of the project are: - The software implementation of the solutions defined and studied during the first year, except the MobileMAN enhanced NIC. - The integration of the developed solutions in a fully functioning testbed. - Preliminary measures of the users’ satisfaction of the ad hoc networking paradigm. These measures will be mainly done by empirical research based on forms to be filled. In addition, some measurements with a small group of users (on a simplified testbed) will be also performed. - To investigate market-based mechanisms for exploiting the self-organised paradigm. This will take into account both the users’ satisfaction and the advantages provided by the MobileMAN environment to some class of applications. Agenda - MobileMAN meeting (Helsinki, 8 June, 2004)
