Selection of Energy and Queue Aware Forwarding Neighbor in Wireless Mesh Network

Wireless Mesh Network has more attractive features such as high-speed last-mile wireless internet access facility, instant deployability and low-cost backhaul services for large area coverage, etc. These features increase the application areas of Wireless Mesh Network (WMN) which in turn, persuade the researchers to pay more attention on this field. Routing plays a vital role in WMN for providing the Quality of Service (QoS) to the users in the network. In this paper, an EQ-AODV protocol is proposed to select a forwarding neighbor based on the factors such as node’s maximum remaining energy and minimum queue length. The above mentioned factors can be incorporated in the multi-channel and multi-interface approach of WMN to increase the capacity and throughput of the network. The EQ-AODV protocol constructs a stable and unbiased traffic route by considering the above mentioned factors. The analysis was carried out by comparing the proposed protocol EQ-AODV with the existing AODV and with the two variations of AODV such as AODV with maximum energy (MaxEnergy) and AODV with minimum queue length (MinQueue). The performance was evaluated in terms of packet delivery ratio, dropped packets, routing overhead, average end-end delay and energy consumed per packet.
