Master Project 1: Interoperability in Smart Distributed Power Systems (collabora<on with IFE) •  Motivation:
•  Challenge to regulate voltage
and frequency in a distributed
renewable energy based power
systems
•  Need to monitor and control
“all” power devices in the
systems
•  The need for all devices to
interoperate
•  Many standards. No universally accepted standards. Legacy
systems
•  Main goals: (1) assess the interoperability requirements
and challenges in local distributed power grids (2)
recommend robust architectural approaches that will ensure
interoperability now and in the future (3) simple

Master Projects 2
with Univ. of Lille, France
Crowd & Sensing
How does it work?
Distributed crowd-sensing
using multi-hop communications
Key Challenge in APISENSE: Privacy to ensure that user data does not disclose sensi/ve informa/on without user’s agreement
Anonymizing Data? not always possible as it is not possible to trust a remote server Solution
A collabora<ve approach: equipments in smartphone’s vicinity to conduct sensiAve treatment Master Project: building a local network of co-­‐
located smartphones (via, e.g., Bluetooth or Wi-­‐Fi Direct) to perform mulA-­‐hop communicaAons Master Project 3: Distribu<ng Sensor Services to IP-­‐enabled systems •  Motivation:
•  Increasing number of
WSNs+IoT applications
•  Distribute WSN services to
modern IT systems
•  The need for a software framework for distributing
sensor services
•  Component-based and standard distribution model
•  Remora component model: developed by ND
•  Distribution model: REST architectural style
•  Main goal: enabling RESTful distribution of services of
Remora components

Master Projects 4: playback of, and seamless switching between, synchronised video files stored in the cloud Synchronized videos
stored in the cloud
It should be possible
to switch from the
video currently playing
to another, with no
pauses or hickups
in playback
The player should
function in all wellknown web browsers,
also on smart phones
