Overview:
This paper approaches the problem of load balancing for wireless multihop networks by distributed optimisation. As an example of a distributed optimisation algorithm for ad hoc networks, an approximation algorithm is used for minimising the maximum network congestion and implements it as a modification of the DSR routing protocol. The algorithm is based on shortest-path computations that are integrated into the DSR route discovery and maintenance process. Therefore, it does not rely on the dissemination of global information within the entire network. The simulation results obtained by the ns2 simulator show a gain of 14% to 69% in the throughput, depending on the setup, compared to DSR for a high network load.
