The continuous improvement of sensor skill and wireless communication is encouraging wireless sensor networking. IEEE 802.15.4 was developed to meet the needs for simple, low-power and low-cost wireless communication. In the past couple of years it has become a popular technology for wireless sensor networks. It is a standard which specifies the physical and MAC layer for Low Rate Wireless Personal Area Networks (LR-WPANs) and it operates primarily in the 2.4GHz ISM band. Wireless Sensor Networks are adopted in many ways, including industrial controls, hospitals, hotels, home/office automation, environmental monitoring etc.
