On the analysis of RED algorithm in ZigBee network for queue management

ZigBee is a sensor based IEEE 802.15.4 wireless standard. ZigBee has taken a role in the utilization of wireless network for diverse applications in home, office or industrial automation. The vast use of ZigBee devices which bring forth a huge application traffic. ZigBee Coordinator processes the application traffic. This traffic waits to be executed in the Coordinator queue. Routers transfer the application traffic to the destination. These huge application traffic can be a cause of queuing drop which reduces throughput as well as increases delay. An active queue management is in demand for ZigBee Coordinator. In this paper, Random Early Detection (RED) algorithm is applied to maintain Coordinator queue for gaining high throughput as the lowest possible delay and data packet dropped. The simulation results show the performance of RED enabled network parameters are better. This analysis will be a convenient direction for the further development of ZigBee network.
