Packet transmitting among the cluster-heads in a cluster based wireless ad hoc networks are carried out through gateway nodes, while nodes in a cluster are communicate through the head node. Existence of multiple gateways between the cluster-heads means multiple path existence. Multiple transmissions of packet though redundancy paths may not desire for efficient resource usage. Therefore, communications between cluster-heads through the most stable gateway is a fascinate solution. In this paper, the authors propose gateway selection methods to support a stable path connection. The characteristics of proposed methods are defined.
