Implementation of a Star-Topology Wireless Sensor Network Based on IEEE 802.15.4 Protocol for Pysiological Signal Detection

With the popularity of Wii game consoles, games and sports have become increasingly closed combination, which has led a wave of new sport. Common to the general family of treadmills, bicycle fitness, and hoop, rope skipping, aerobic gymnastics and other indoor sports, will also become more popular. However, most of the sport equipments is not attached to sensors, even if equipped with pulse, temperature and other sensors, it is often due to memory restrictions and computing modules that can not be a long period of recording or coming up with useful data, with the passage of time, most of them abandoned by the user, greatly reduced the original good intentions of sensor. his paper is mainly on how to develop a Wireless Sensor Networks rooted in the IEEE 802.15.4/Zigbee, to provide sensor data transmission ways, and through the NS2 simulation to determine the details of the wireless network architecture. Then the overall system is made and test system performance, and give the direction of future development and suggestions.
