Abstract: A dynamic topology is distinguishing feature and challenge of wireless ad hoc networks. Links between the nodes are created and broken, as the node moves within the network. This node mobility affects not only the source and/or multicast receiver, as in conventional wireless network, but also intermediate nodes, due to network mutihop nature. Furthermore, the packets are more likely to be lost due to external environmental factors wireless interference if the signal strength is not strong enough. The major strength of web-structured multicast routing protocol is simplicity. This study propose an improved stability scheme to estimate link stability based on signal strength. We perform simulations to investigate the benefits and costs of using signal strength as route selection criteria. The proposed method increase total number of bytes received by the receiver and decrease the control overhead compare with the basic WSMRP.
