Performance Comparison of 802.11and 802.15.4 Based Networks
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.
