QOS Analysis in IEEE 802.15.4 and Impact of Flag Mobility on Network Performance in WSN
Wireless Sensor Network (WSN) consists of large number of sensor nodes that are capable of communication, computation and sensing. Inherent limitations of WSN include limited storage, processing and transmission power. As compared to other network topologies, WSN has less communication Protocols mainly Zigbee/IEEE 802.15.4. IEEE 802.15.4 is a new standard, uniquely designed for Low Rate Wireless Personal Area Network (LR-WPAN), which is developed for applications that demand low throughput. IEEE 802.15.4 was designed for short range, low power, low complexity, low rate and low cost wireless network which provides two way wireless communication technology.
