Abstract — Spatio-Temporal processing 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 layer. In this paper, we propose an outage based performance analysis of collaborative STP for WSNs. After an accurate characterization of the wireless channel, we derive the outage statistics as function of the STP coefficients, and investigate the effects of STP on the probability, average duration and rate of the outage events. Furthermore, we show that a proper control policy of the STP coefficients can be derived according to the requirements from the applications and WSNs communication layers.
