Control MethodforWirelessMesh Networks
Atsushi Yoshida, Masayuki Murata · 2008
Thispaperproposes acongestion control method fora wireless meshnetwork. Eachintermediate nodehas separate transmission buffers foreachofnexthopnodes. By following themathematical reaction-diffusion formulation, an intermediate nodesimultaneously performs 'local optimization' control thatbalances buffer occupancy amongitstransmission buffers and'global optimization' control thatsuppresses the variation inoccupancy between intermediate nodesalongthe path. Asaresult, packets aredistributed overthewholepathand further anetwork andbuffer overflow isprevented. Theresults ofoursimulation showthattheproposed methodcanprovide better communication quality underloaded condition. Congestion Control, LocalOptimization, Global Optimization.
