We consider achieving max-min fairness in 802.11e based multi-hop wireless networks. We propose an approach which makes use of the TXOP mechanism in combination with an automatic contention window size tuning algorithm based on channel state sensing. Simulation results show that the proposed approach can provide a good approximation to per-flow max-min fairness and that this is achieved regardless...
The current low throughput of wireless ad hoc networks is greatly caused by the inefficiency of spectrum usage. With distributed scheduling/spectrum allocation, better spectrum efficiency can be achieved. However, most distributed algorithms consider the neighbors' traffic independent of each other and ignore the multi-hop nature of flows, leading to the spectrum wastage and inefficiency. By incorporating...
Spectrum sharing is a crucial issue to the overall throughput performance of multi-hop wireless networks. Traditional distributed random medium access control (MAC), such as IEEE 802.11, lacks of efficiency of spectrum usage, while centralized scheduling is not practical for large scale ad hoc networks. It is observed that for multi-hop wireless networks, it is hard to resolve the scheduling conflict,...
