摘要:Wireless Sensor Networks (WSNs) are a collection of nodes organized into a cooperative network. Harsh and dynamic physical environments and extremely limited resources are major obstacles for satisfying QoS metrics. This paper proposes and analyzes an Base station Controlled Adaptive Clustering Protocol (BCACP) 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 BCACP reduces overall energy consumption and improves network lifetime while maintaining required QoS.
