A Cooperative Transmission Approach to Reduce End-to-End Delay in Multi Hop Wireless Ad-Hoc Networks

In this paper, we present a cooperative transmission approach to reduce the end-to-end delay in the context of AODV based multi hop wireless networks. The underneath idea is to effectively increase the average reach of each hop so that data packets can arrive at the destination in less number of hops with lower end-to-end delay. The existing approaches of increasing transmitted power are not effective while they increase the network interferences. Unlike them, we exploit the concept of cooperative beamforming to reduce the end-to-end delay by increasing the effective communication distances and reducing the communication interferences in wireless ad-hoc networks.
