Survey of Energy Efficient Multicast Routing Protocols in Manet
Although establishing correct and efficient routes is an important design issue in Mobile Ad hoc NETworks (MANETs), a more challenging goal is to provide energy efficient routes because mobile nodes' operation time is the most critical limiting factor. This paper surveys and analyses the energy aware routing protocols proposed for MANETs. The authors minimize either the active communication energy required to transmit or receive packets or the inactive energy consumed when a mobile node stays idle but listens to the wireless medium for any possible communication requests from other nodes. Transmission power control approach and load distribution approach belong to the former category, and sleep/power-down mode approach belongs to the latter category.
