OPTIMAL-RELIABLE DELAY ROUTING ALGORITHM FOR LOW DUTY CYCLE WSNS BASED ON QUORUM
摘要
Abstract
In wireless sensor networks,asynchronous duty cycle technique can significantly reduce energy consumption.However,a high end-to-end time delay is caused by low-duty-cycle networks.Therefore,an Optimal-Reliable delay routing algorithm for low duty cycle WSNs based on Quorum(ORDA)is proposed to solve the problem.This algorithm combines the asynchronous duty cycle networks with the actual link,and the neighbor discovery delay of each node is constantly changed at different time.Firstly,each node chooses its own quorum type ac-cording to the network load and calculates the overlapping time slots numbers of neighbor nodes by the quorum characteristics.Then,the ex-pected value of successful forwarding between neighbor nodes is computed with the link quality,and the more reliable node is chosen as a for-warding node.The simulation experiments show that the algorithm can not only reduce the end-to-end delay,but also obtain a high forwarding success rate.关键词
