Wireless ad-hoc networks emerged as a promising technology that offers low-cost high-bandwidth community wireless services. A WAN consists of a set of stationary wireless routers that form a multi hop backbone, and a set of mobile clients that communicate via the wireless backbone. Many applications can benefit from the service provided by multicast routing protocols. In a typical high-throughput multicast protocol, nodes periodically send probes to their neighbours to measure the quality of their adjacent links. During route discovery, a node estimates the cost of the path by combining its own measured metric of adjacent links with the path cost accumulated on the route discovery packet.
