Performance analysis of IEEE 802.15.4 / ZIGBEE networks
MetadataShow full item record
We analyze the performance of IEEE 802.15.4 / ZigBee networks. In order to evaluate the performance, we design various sceneries varying number of nodes and network area. We research on self-healing mechanism in ZigBee, the technology is a self-organized and selfhealing wireless communication technology with low power-consumption, large network capacity and small time-delay. With ZigBee technology a wireless personal area network in low data rate could be constructed. We evaluate the performance of designed networks using multimedia traffics. In particular, we present findings on network performance when a node is constantly moving and changing routes. We evaluate for packet delivery ratio when the nodes are moving and when they are fixed and range was within 100 meters. Our evaluation results indicate that ZigBee router typically suffers less packet losses under mobile scenarios. Also survey the end to end delays and through puts for different number of mobile nodes by using single router. As a simulator we use OPNET simulation tool. It will help people to know why anyone will choose ZIGBEE not others.
