A random sending time interval is set for controlling message from cluster head to reduce the success rate of eavesdropping, and then a united message format is designed for all kinds of messages of Ad hoc to prevent the adversary getting efficient information by the format analysis, lastly, the mesh? based management is designed for wireless network clustering and routing, by which when new nodes are added to the cluster, it is unnecessary to send a request to cluster head for setting up efficient linkages with the members inside the cluster. As the proposed algorithm considers the lifetime of the entire network,
