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...
We develop an optimization technique for a two way asynchronous relay network. A space-time processing based transceiver is proposed for spatial multiplexing in a two-way relay network. The optimization aims to minimize the transmission power at the relays while satisfying the signal to interference-plus-noise ratio (SINR) target for each user. The problem is solved using semidefinite programming.
