Channel assignment to minimize interference in multiradio wireless mesh networks

Abstract

Breadth First Search Channel Assignment(BFSCA) is a hybrid channel assignment algorithm that utilize multiple radio interfaces to improve the throughput and minimize the interference within the wireless mesh network and between the mesh network and co-located wireless mesh networks. This new channel assignment scheme allow different nodes in the same network to communicate with each other without causing too much interference to their neighbors. It is introducing Multiradio Conflict Graph(MCG) to model interference in the wireless mesh network. Breadth First Search Channel Assignment considers both the fixed channels(static) and the dynamic channels to reduce interference of the network. BFSCA will increase the network throughput greatly. © 2011 Springer-Verlag Berlin Heidelberg.
