In this paper, we address the problem of packet forwarding in multi-hop wireless networks of nodes equipped with multiple antennas. Through the use of MIMO (multiple-input multiple-output) technology, the physical layer is able to superimpose multiple concurrent information flows, thereby increasing the communications parallelism in the network. We propose a cooperative cross-layer scheme that integrates...
In this paper, the problem of energy saving in cooperative multi-hop wireless sensor networks is studied with the constraint of a given outage probability. In these networks, each node transmits its signal to the next mcoop nodes on the route ending with the sink node. Rice and Nakagami channels are considered. In this paper, we derive the upper bound of the end to end (e-2-e) outage probability for...
