Routing performance improvement using dynamic threshold based on measured SNR for OFDM based ad-hoc cooperative wireless networks

Abstract

In this paper we propose and discuss the Channel State Information (CSI) based routing scheme for ad hoc cooperative wireless networks. The proposed approach takes into consideration the wireless channel quality of all available ad hoc nodes to choose for the best route on the fly for packet delivery over the cooperative network and making sure that the conventional TCP will still be effective. The CSI scheme will apply dynamic threshold based on measured SNR to minimize error while sending data over the network.
