Effective Suppression of Unnecessary Hello Messages to Provide Energy Efficiency for On- Demand Routing Protocols In MANET

Abstract

The aim of this project is to propose an adaptive Hello messaging scheme for neighbor discovery by effectively suppressing unnecessary Hello messages. The proposed scheme dynamically adjusts Hello intervals, and does not increase the risk that a sender will transmit a packet through a broken link that has not been detected by Hello messaging; we call this the probability of failure of detection of an unavailable link (PFD). To estimate this risk, we exploit an average event interval, that is, an average time gap between two consecutive events (i.e., sending or receiving a data packet) on a node. If a node is not involved in a communication for a given period, it does not need to maintain the status of the link; Hello packets broadcasted during this period are unnecessary. It will reduce the energy consumption. Ant colony optimization technique is involved in this paper for discover the neighbour node efficiently.
