Energy Efficient Cooperative Relay Network Design

Azhar Hussain Khan | G. Prapulla

Abstract: Relay links play an important role in the design of wireless networks. Consider a single antenna transceivers and multiple single antenna relay nodes, the path between the transceivers and relays will be subjected to different propagation delays. A simple amplify and forward relaying protocol is used in this paper reason being the simplicity. In this paper a novel performance metric PN-SNR is used to design an energy efficient cooperative relay network. For the single and multiple relay network scenario the PN-SNR maximization problem is solved and the performance is analysed. The analysis is extended to multi antenna transceivers and compared. The paper emphasizes the potential of PN-SNR in designing the energy efficient relay network.
