Efficient Neighbor Routing in Wireless Mesh Network

Abstract

Wireless Mesh Network (WMN) is a rising technology in the wireless field and has the advanced features like self-healing, self-configuring, low deployment cost, easy network maintenance and robustness.  The latest research is paying more interest on the efficient route construction of the networks. The efficient route can be constructed by choosing the best neighbor for transmitting the packets. The on-demand protocol AODV selects a route based only on the minimum hop-count, but this is not enough for constructing the best route. For selecting the best route, node’s energy is an important constraint. This paper considers maximal net energy neighbor for routing the packets.  The AODV protocol is enhanced to construct a route with maximal energy.  For the performance evaluation the packet delivery ratio, dropped packets, and energy consumed per packet metrics were analyzed using NS-2 simulator by varying energy ranges. The observed results prove that there is a substantial increase in packet delivery ratio and throughput and decrease in dropped packets and energy consumed per packet.
