Abstract:

By assigning orthogonal channels to neighboring nodes, one can minimize both types of interferences and allow concurrent transmissions within the neighborhood, thus improving the throughput and delay performance of the ad hoc network the capacity of mobile ad hoc networks is constrained by the intra-flow interference introduced by adjacent nodes on the same path, and interflow interference generated by nodes from neighboring paths three novel distributed channel assignment protocols for multi-channel mobile ad hoc networks protocols combine channel assignment with distributed on-demand routing, and only assign channels to active nodes proposed protocols can effectively increase throughput and reduce delay, as compared to several existing schemes, thus providing an effective solution to the low capacity problem in multi-hop wireless networks.
