This paper investigates the accuracy performance of received signal strength (RSS)-based factor graph (FG) geolocation technique in outdoor environment of wireless sensor networks (WSN). The current RSS-based FG geolocation technique is evaluated in small area of indoor environment with shadowing fading channel. Therefore, this paper considers the path-loss fading channel by averaging RSS samples of each monitoring spot and target, where the averaging is long enough to eliminate the shadowing and small-scale fading component of RSS. This paper shows the effect of the number and wide area of monitoring spot to the accuracy of RSS-based FG geolocation technique in outdoor environment.
