Performance Study of Virtual Fence Unit Using Wireless Sensor Network

In this paper, the authors present the experiments and performance analysis of virtual fence unit consists of microwave motion detector and IEEE 802.15.4 Wireless Sensor Network (WSN) for maximum sensing range. In particular, the analysis is focusing on the maximum sensing range in terms of azimuth angle, height, sensitivity level for indoor and outdoor implementation. The WSN platform is developed using Octopus II sensor nodes while the microwave motion detector is HB100 which detects the movement using Doppler effect. Results show the maximum sensing range of virtual fence unit is decreasing as azimuth angle increasing.
