Multicasting in mobile ad hoc networks has found many real life applications such as teleconferencing, video conferencing, and multi-user gaming. Despite that multicasting can utilize the broadcast nature of the network, it has been facing many challenges such as limited node power. Multicast routing protocols and metrics used to build multicast routes have direct impacts on power consumption in mobile networks. In this work new unconventional metrics are considered to achieve more reliable and stable routing paths. Routing decisions in the new power aware protocol introduced in this book will be taken in a manner such that the longest living path would be chosen, and at the same time not being greedy in killing some nodes.
