Performance Analysis of Collaborative Spatio-Temporal Processing for Wireless Sensor Networks

Spatio-Temporal Processing (STP) is a control technique to increase the quality of the received signals in wireless networks. Outage events have a strong influence not only on the performance of the physical layer, but also on routing, MAC, and application layers. In this paper, the authors propose an outage based performance analysis of collaborative STP for Wireless Sensor Networks (WSNs). After an accurate characterization of the wireless channel, the authors derive the outage statistics as a function of the STP coefficients, and investigate the effects of STP on the probability, average duration and rate of the outage events.
