However, recently multicast routing becomes an important issue because the applications using this technique become popular. As a result, several multicast routing protocols in ad hoc networks have been proposed. MAODV (Multicast Ad hoc On-demand Distance Vector) is a multicast routing protocol that was intended for use in mobile ad‐hoc networks by the IETF MANET Working Group. MAODV adopts the number of hops as its routing metric and thus intends to derive shortest‐path routes. In wireless ad-hoc networks, usually, each mobile host has limited bandwidth, memory, and power. Especially power, there have been many existing routing algorithms proposed for this issue, but how to design an efficient and practical routing protocol is a challenge. The purpose of this paper is to revise MAODV’s routing metric and design an Energy-Aware MAODV routing protocol such that the total energy consumption for each path is minimized. The revised MAODV is implemented over NS2 v2.31. A serial of simulations is conducted to evaluated and compare the original MAODV and Energy-Aware MAODV.
