Abstract

Cognitive wireless ad hoc is highly focused as a promising future wireless technology. However, cognitive wireless ad hoc networks have some difficulties of neighbor discovery and routing. For helping neighbor discovery and routing in the cognitive wireless ad hoc networks, we introduce a common link control radio (CLCR) that is a common active wireless system of cognitive terminals. In addition, we propose a novel cognitive ad hoc routing protocol based on a common link control radio (CLCR) called a minimum weight routing protocol. We show that the proposed routing protocol can greatly reduce communication overhead in cognitive wireless ad hoc networks.
