An Energy Efficient Reliability Scheme for Event Driven Service in Wireless Sensor Actuator Networks

Wireless sensor network has been evolving to wireless sensor actuator networks (WSAN), which is supposed to provide more dynamic services based on events from sensor nodes. WSANs require event reliability to support more accurate services. The optimum number of event notification messages from sensor nodes is the prerequisite for the further service reliability in WSANs. In this paper, we provide the analysis about how the number of event notification affects the energy consumption of actuator node in wireless sensor actuator networks.
