A NOVEL APPROACH FOR IMPROVEMENT IN FLOODING OF AODV ROUTING FOR MANET USING SECTOR ANTENNA

Abstract

Abstract A set of wireless nodes or routers coming together to form a network in which every node acts as a router can be defined as a mobile ad hoc network (MANET). This kind of networks is currently one of the most important research subjects, due to the huge variety of applications (emergency, military, etc.). In MANETs, each node acts both as host and as router, thus, it must be capable of forwarding packets to other nodes. Topologies of these networks change frequently. AODV routing protocol is a type of reactive routing which uses blindly flooding for finding the destination node. For highly density network, AODV routing protocol causes extra redundant route request packet which consumes unnecessary bandwidth of the network and wastes energy of computing nodes. Because energy consumption is major concern in the mobile ad hoc network. So in the proposed strategy, improvement of the basic flooding technique of AODV routing by using sector antenna for different regular topologies or models have been implemented. All the standard model provides a set of nodes with uniform density and distribution. The number of messages sent along various links or the number of links which are used is an effective and accurate metric for comparative analysis. The proposed algorithm uses sector antenna to reduce redundant rebroadcast in flooding of AODV routing. Hence resulted in to saving the energy of the nodes and consumes less bandwidth of the network as compared to simple flooding of AODV routing.
