Abstract

This paper is devoted to the development of cognitive routing techniques for a wireless ad hoc network in order to improve scalability and effectively the supportable capacity. Different routing strategies are examined and a novel capacity-based routing strategy is emphasized. Its capacity performance is evaluated using conventional shortest path routing as a benchmark. It shows the proposed capacity-based routing strategy can reduce the overall interference level in the system by shifting traffic to the edge of the network. It can also support more originating capacity compared with the shortest path routing strategy where each node has a maximum capacity constraint.
