Abstract
The idea of Wireless Personal Area Network (WPAN) is using a short range and low power wireless network technology to connect certain devices such as cell-phones, PDAs, computers and peripherals and other home appliances. Wireless Sensor Network (WSN) is one of the technologies to realize WPAN. It can setup a low cost, low power and low data transfer rate wireless network in a particular area by deploying several network node. The applications include building automation, industrial control, remote control and healthcare. This thesis proposes a wireless sensor network system using ZigBee. We use embedded controller and ZigBee module to implement a programmable network node, and compile suitable transmission protocol and communication logics. We set up a wireless sensor network in distributed structure by several network nodes and PC, in which PC is the master control center. Finally, we would combine this system with a wheeled-robot to verify its efficacy in the movable object location estimation and loci tracking.
