A Novel Cluster-Based Architecture of Cognitive Wireless Ad-Hoc Networks

Cognitive radio (CR) technology makes spectrum usage paradigm shifting from the traditional command and control allocation scheme to the open spectrum allocation scheme. With the introduction of CR, wireless ad-hoc networks meet new opportunities and challenges. Motivated by the CogMesh network, this paper proposes a novel cluster-based CogAd-hoc architecure. The CogAd-hoc network provide a new kind of cooperation mode which improves the efficiency of data forwarding and has excellent load balance feature. This paper gives the overview of the CogAd-hoc network and identifies issues in such a network.
