在移动传感器网络中,由于网络的拓扑结构在不断的变化,传统的确定性路由算法并不适用.提出一种新的基于概率分布的动态预测的数据发送策略.该策略利用网络中节点的移动性创建动态的数据传输路径,使得网络中数据传递的时延接近于最优性能,同时确保网络耗能的高效性.实验显示,提出的策略在传输距离较大、节点移动速度快的网络中更具优势.

In mobile wireless sensor networks (MWSN),due to the dynamic changes in network topology,the traditional pre-determined routing algorithms are not suitable. In this paper,we propose a novel probability distribution based dynamic and predicted (PDDP) data forward strategy.In this strategy,we utilize the mobility of sensor nodes to create dynamic path which can achieve low network delay that close to optimum value,at the same time,consume network resource efficiently.Experiments show that the proposed strategy has more advantages when the nodes in network have larger transmission range with faster speed.
