Maximization of Network Lifetime Using LAR Protocol in Wireless Ad Hoc Network

Boomathi M , Nithyakumar M

Mobile Ad-hoc Network (MANET) is a group of mobile nodes that forms a network. Power constraint is a one of the major design constraints in mobile ad-hoc network. The mobile nodes are battery driven, hence it is important to extend the energy of the each node to improve the operational lifetime. The proposed energy aware routing algorithms for MANETs, called LAR (Location Aided Routing) is based on a fully distributed and a threshold based certified lake address allocation model. Energy Efficient Location Aided Routing (EELAR) Protocol was developed on the concept of the Location Aided Routing (LAR). EELAR makes considerable reduction in the energy consumption of the node batteries by limiting the area of discovering a new route to a smaller zone. Thus, the control packet overhead is reduced. In EELAR, a reference wireless base station is used and the network’s circular area centered at the base station is divided into six equal sub-areas. While LAR is deployed, the increasing in communication transparency and latency is fairly reasonable then it’s also used to dynamic based allocation protocol. The availability and the security are so guaranteed for the MANET auto configuration service while unmoving ensuring efficiently both network and security parameters for a newly arrived node.
