Reliability Considered Routing Protocol in Wireless Sensor Networks
In some specific applications such as industrial control,emergency response,to guarantee the quality of network, some other requirements such as real-time and reliability of transportation,beside the energy consumption,should be considered. In this paper,a novel routing protocol named DETR (delay-energy tradeoff with reliable communication)for Wireless Sensor Networks is proposed,which considers the joint performance indexes of real-time,energy efficiency and reliability.In DETR,a node,which is preparing to delivery data packets to sink node,estimates the energy cost,delay and reliability using local information gained from neighbor nodes.The candidate of next hop node is chosen from the node set firstly in which the member has higher level of residual energy.To enhance real-time delivery,it will choose the node with higher velocity as the possible next hop node.To achieve reliability,it chooses the path which has the best reliability instead of considering dropping packets. Simulation results show that DETR has better performances in term of energy consumption,network lifetime and transmitting delay.
