Abstract: To establish a valid cluster structure of Ad Hoc network for effective use of multi-channel and enhancement of system capacity and network performance, an improved algorithm based on the high connectivity clustering algorithm is proposed. By using the broadcast channels and confining the size of cluster, the algorithm realizes the multihop clustering from normal node to cluster head. The performance of the algorithm is envalued by simulation. Results indicate that the proposed algorithm keeps more suitable clustering numbers and enhances the load balancing of cluster head.

Key words: Ad Hoc network, clustering, connectivity, load balancing
