Workshop 1
FRIDAY 24.12.2010
Time 8:00_12:00
Room: 201
Topic: Wireless Self-organised networks: Research issue and challenges
Presenter: Dr Mona Ghassemian, University of Greenwich/ King’s College London, UK

Future network design requires provisioning of the future application scenarios and technologies including the emerging wireless sensor networks. Two known categories for wireless self-organised network scenarios are mobile ad hoc networks and wireless sensor networks. Existence of wireless communication links between nodes in both scenarios makes the nodes to move randomly in a bounded area which results in topology changes. In such environments, reliable and energy-efficient data delivery is important. These networks will connect a large amount of highly resource constrained, highly heterogeneous set of nodes ubiquitously communicating in a wireless fashion. The aim of this tutorial is to expose an industrial and academic audience to the cutting-edge R&D challenges associated with the protocol-related analysis and design of this disruptive technology.

Workshop 2
FRIDAY 24.12.2010
Time 8:00_12:00
Room: 202
Topic: New Achievable Rate Regions for Interference and Cognitive Radio Channels
Presenter: Dr Hodtani, Department of Electrical Engineering, Ferdowsi University of Mashhad, Iran

First, the Han-Kobayashi (HK) rate region for general interference channel (IC) is partially improved allowing the input random variables to be correlated. Second, considering a general input distribution and using a combination of the HK jointly decoding strategy, Marton like coding and binning scheme, we obtain a new achievable rate region for the cognitive radio channel (CRC) and show that this new region (i) is a generalized and improved version of the Devroye-Mitran-Tarokh (DMT) region, (ii) has an interesting interpretation, i.e., any rate in the region has generally three additional terms in comparison with the HK region and (iii) contains some of simply described rate regions as its subsets.
