On the availability versus transmitted power of wireless sensor networks in Rayleigh multipath fading environments

Abstract

This paper presents simulation results for full availability of a wireless sensor network depending on the RF output power of the network nodes in Rayleigh multipath fading environment. Outage probability, relating to the situation in which any one of the sensors is unavailable, is computed by means of numerical simulation, and discussed. The results indicate that the trade-of between the outage probability and the energy efficiency of the network nodes should be sought, resulting in lowest required output power for the highest tolerable outage threshold.
