Research area: QoS management by emergent behavior

Applying swarm intelligence techniques to wireless mesh networks
Wireless mesh networks (WMN) are an emerging class of networks. WMN are wireless backhaul networks constituted of static and grid-powered nodes and shall provide wireless access to the Internet over wide areas using a limited number of gateways. The idea lying behind is to turn isolated muti-hop ad-hoc networks into a flexible and low cost extension of wired infrastructures.
WMN networks are wireless multi-* networks; they may be multi-hop, multi-homed, multi-destination, multi-route, multi-channel, multi-interface, multi-technology etc. They present both opportunities - e.g. for multi-path routing load balancing using the intrinsic redundancy, channel diversity - and challenges - e.g. dependability, fairness, scalability and efficient usage of the radio resource.
The research work undertaken builds up on this last consideration and aims at applying the swarm intelligence heuristic to take up (part of) the challenges.

My supervisor is Professor Bjarne E. Helvik.

Part of this work is conducted within the EU FP7 Network of Excellence Euro-NF and its predecessors the EU FP6 Networks of Excellence Euro-NGI/Euro-FGI.
