A novel adaptive clustering protocol, called the mobile clustering protocol, is presented firstly. It acquires network control architecture rapidly and adapts to topological changes with less control overhead than those proposed so far. It also supports node mobility and maintains the stability and robustness of the network architecture. The new method to adopt overlapping clusters for cluster size optimization is proposed secondly. The area with high node density is divided into clusters with a small number of nodes, so that the maximum throughput of each node can be increased. The intelligent control protocol is proposed finally to prevent gateways from becoming communication bottlenecks among clusters with different channels and avoid missing packets on their non-sensing channels. Simulation and numerical results are shown.
