Aleksi Penttinen received his M.Sc.in Engineering Physic and Mathematics from Helsinki University of Technology in 2001. He is currently a PhD student in the teletraffic theory group at Networking laboratory of Helsinki University of Technology.
I will discuss two specific topics in ad hoc networking, namely development in multicast routing algorithms and, in more detail, balanced fairness in ad hoc networks. Furthermore, a brief introduction to the research activities in Networking laboratory of Helsinki University of Technology is included. Balanced fairness is a new resource sharing concept recently introduced by Bonald and Proutiere. We have extended the use of this notion to wireless networks where the link capacities at the flow level are not fixed but depend on the scheduling of transmission rights to interfering nodes on a faster time scale. The balance requirement together with the requirement of maximal use of the network’s resources jointly determine both a unique state-dependent scheduling and bandwidth sharing between the contending flows. The flow level performance under the resulting scheme is insensitive to detailed traffic characteristics, e.g., flow size distribution.
