Diagnosis of Failures in Zigbee Based Wireless Sensor Networks

In this paper, based on the characteristics of ZigBee protocol, ZigBee technology is used to model and simulate a wireless sensor network. Nodes failures and their effect on the traffic are considered in different scenarios for cluster-tree topology to certify the reliability of this communication network. The parameters: throughput, delay, data traffic sent, and data traffic received are measured during these scenarios. These scenarios are performed taking into account the specific features and recommendations of the IEEE 802.15.4/ZigBee standard using OPNET Modeler 14.5. Simulation results quantify the impact of a ZigBee device failure on the performance factors.
