A Comparative Analysis for Detecting Uncertain Deterioration of Node Energy in MANET through Trust Based Solution

Abstract

Energy is consumed in MANET during the transmission and reception of data, propagation of control packets, retransmission and overhearing. We concentrate in reducing the energy consumption during the transmission and reception of data. Each node in MANET transmits data with the maximum energy regardless of the distance between the nodes. Also the mobile nodes expend some energy in transmission and reception of data. We have utilized the metrics received signal strength, link quality and the distance between the nodes to compute the energy required to transmit the data from a node to its neighboring node. The energy computed is involved in the selection of the optimal path which requires minimum energy to route the data from source to destination. Nodes within an ad hoc network generally rely on batteries (or exhaustive energy sources) for energy. Since these energy sources have a limited lifetime, power availability is one of the most important constraints for the operation of the ad hoc network.
