Energy Efficient Path Determination in WANET

ABSTRACT: Two algorithms were used in Energy-Efficient Reliable Routing in wireless Ad Hoc networks. Reliable minimum energy cost routing(RMECR) and Reliable minimum energy routing(RMER) . It reduces energy cost and data communication in wireless network . RMECR can increase the operational lifetime of the network using energy efficient reliable routes. RMECR have two types of networks : Hop by Hop and End by End. In the HBH system, a lost packet in each hop is retransmitted by the sender to ensure link level reliability. In EBE the ACKs are generated only at the destination and retransmissions happen only between the end nodes. RMER finds routes minimizing the energy consumed to route a packet from a source node to a destination node. It also extends the operational lifetime of the network . Disadvantages are End to end delay is maximum, Overusing of nodes may occur , Energy loss is high ,Retransmission of packets high. In this paper , we propose an algorithm called Enhanced RMECR (ERMECR) which is used to find out the high energy intermediators. Here the data is to be transmitted through the path which contains the high energy. Besides the energy constraints are considered for the path selection process. The path selection from source to destination is least hop count with high energy
