A power managed based multicast routing protocol for mobile ad hoc network

The popularity of portable computing devices coupled with the recent developments in group oriented computing, has not only made the design of mobile and wireless networks important but the design of flexible, efficient and portable multicast routing algorithm for highly mobile ad hoc networks a very difficult task. Ad hoc network is a collection of wireless, mobile, dynamic, and arbitrarily located nodes. The nodes cooperate with each other to create an infra structure less temporary low cost network. The high mobility of nodes result in rapid changes in the routes, thus requiring some mechanism for determining new routes with minimum overheads and bandwidth consumption. Such infrastructure less networks use multicast routing protocols to manage random and uncertain events like rescue missions, disaster recovery, crowd control etc. The existing multicast routing protocols suffer from many drawbacks (K. Obraczka and G, Tsufik, 1998) (Ching-Chuan Chiang et al., 1997). This paper presents a protocol called "a power managed based multicast routing protocol (PMMRP)" which has extended the lifetime of each mobile node by evenly utilization of power
