An energy-calculable star wireless sensor network protocol

An ultra-low-power protocol is proposed for wireless sensor network based on two-channel communication.By analyzing the anti-collision theory of the protocol,the design principles of the network parameters are given.It shows the association algorithm between power consumption of the sensor node and the lifetime of sensor network,and this algorithm is validated by the network simulation software named OMNeT++.The result shows that by reducing the complexity of the protocol and controlling the working process of the network,it can reduce the energy consumption,extend the life of the entire wireless sensor network,and forecast the lifetime of wireless sensor network.
