Wireless Sensor Networks (WSN) has been researched in recent years. WSNs have inherent and unique characteristics compared with traditional networks. It consists of light-weight; low power and small size Sensor Nodes (SNs). They have ability to monitor, calculate and communicate wirelessly. Sensor nodes should send their collected data to a determined node called Sink. The sink processes data and performs appropriate actions. In this paper, an accurate simulation model, the behavior of a mobile Zigbee node passing through the radius of multiple PANs is examined using OPNET simulator. The performance metrics like: PAN Affiliation, Data Dropped, Traffic Received are reported.
