Reliable Multicast and Energy Conservation in MANET: A Survey

Abstract

Mobile ad hoc networks are networks without any infrastructure and topology. They are self organized and battery powered networks with a large number of mobile nodes. Limited battery power is the most important issue considered during the design of a mobile ad hoc network. Frequent recharging or replacement of battery is not so easy and is impossible in some applications such as rescue operations. These networks are used in areas, where the infrastructure of communication is damaged due to some problem, to establish a communication media until infrastructure is restructured. To improve the life time of the network the conservation of energy in each node is very important. Each node act as a router and as a receiver simultaneously. This paper surveys some algorithms to improve the lifetime of the network and some algorithms to improve the reliability of the network. This paper surveys some energy conservation algorithms and some lightweight protocols to improve the reliability of the network. Keywords: MANET, Multicast, Residual energy, Relay capacity, Energy conservation, Lifetime of the network, Lightweight services.
