Abstract

Mobile Ad-Hoc Network (MANET) is a wireless ad-hoc network comprising of mobile devices which undergo peer to peer routing, to provide network connectivity instead of pre-existing network infrastructure. Despite its simplicity of network infrastructure, however it poses challenges of variable link capacity, dynamic topology, exhaustible battery power of nodes and limited physical security. In MANET, broadcasting is a conventional mechanism carried out to deliver messages from source node to all other nodes in MANET. Flooding is commonly used method for broadcasting of Route Request (RREQ) packet which is prone to broadcast storm problem. As a result, there is a need of an efficient routing strategy to build a reliable route which can neglect high variation of signal strength, collision and draining of battery power. In this paper, a new approach is introduced to rebroadcast based on an efficiency factor called delay and to provide a route repairing procedure against link failures. Our approach also focuses on disseminating neighbor coverage knowledge within nodes in order to avoid duplication problem of RREQ packets. Simulation results of our approach reveal better performance in terms of metrics such as packet delivery ratio, energy consumption and control overhead.
