The Impact of Time-Reversal Modulation on the Performance of Cooperative Relaying Strategies in Wireless Networks

The predominate traffic patterns in a wireless sensor network are many-to-one and one-to-many communication. Hence, the performance of wireless sensor networks is characterized by the rate at which data can be disseminated from or aggregated to a data sink. In this paper, we consider the data aggregation problem. We demonstrate that a data aggregation rate of Θ logn n ( ) can be achieved in wireless sensor networks using a generalization of cooperative beamforming called cooperative time-reversal communication.
