摘要
以节能和提高传输可靠性为目的,提出了一种基于最小跳的WSN传输可靠性路由算法。数据分组沿最小跳的路径向Sink节点传输,并在路由时选择可靠性评估值较高的"下一跳信任节点"进行转发,算法采用逐跳的NACK机制实现分组的丢失检测和重传,并能有效处理数据拥塞状况。理论分析和仿真实验表明,该算法具有良好的性能。
For the purpose of energy conservation and transport reliability improvement,a new reliable routing algorithm for WSN transport based on minimum hop is proposed.Data packet is sent by the minimum hop path to Sink node,the″next hop trustful node″with higher reliable evaluation value will be chosen as the next hop node when routing.The loss detection and recovery of packets is achieved through a hop-by-hop NACK mechanism.The algorithm can also effectively deal with the situation of data congestion.According to theoretical analysis and simulation experiment,this algorithm has good performance.
