In Wireless Sensor Networks (WSNs), stochastic reliable transmission protocols, which improve reliability of the delivery process by transmitting redundant packets, have been proved to have advantage of energy efficiency over the retransmission one. But the burst and deep fading characteristic of the error prone wireless links in WSNs reduces the practicability of this kind of protocols. To solve...
In this paper, we investigate the issue of cooperative node selection in MIMO communications for wireless ad hoc/sensor networks, where a source node is surrounded by multiple neighbors and all of them are equipped with a single antenna. Given energy, delay and data rate constraints, a source node dynamically chooses its cooperating nodes from its neighbors to form a virtual MIMO system with the destination...
