Fault Tolerant QoS Adaptive Clustering for Wireless Sensor Networks

摘要

This paper proposes and analyzes an Energy Efficient Fault Tolerant QoS Adaptive Clustering Algorithm (FTQAC) for Wireless sensor networks suitable to support real-time traffic. The protocol achieves fault tolerance and energy efficiency through a dual cluster head mechanism and guarantees the desired QoS by including delay and bandwidth parameters in the route selection process. Simulation results indicate that FTQAC reduces overall energy consumption and improves network lifetime while maintaining required QoS.
