针对延迟容忍传感网中节点的间歇连通性问题,以及在网络中的节点带有社会自私性和网络消息投递成功率的条件下,对减少传输延迟及通信开销等问题进行了研究.提出了一种基于节点的自私性延迟容忍路由算法(DTSNS).首先对活动区域网格化,方便利用马尔科夫的性质对节点下一步移动的位置进行预测;再基于节点的自私性对其信誉度进行估算,目的是减少网络的通信开销及提高消息投递成功率;接着在时延约束条件下提出了延迟容忍路由算法;最后经过仿真实验得出,在大规模网络中DTSNS和Spray and Focus、Spray and Wait以及Epidemic等算法相比较,DTSNS数据递交率高、消息时延和资源消耗小的特点.

For intermittent connectivity problems in the delay and tolerance sensor network, with node have social selfish and information has delivery success rate under the condition, to reduce transmission delay and communication overhead are studied. Put forward delay tolerant routing algorithm based on selfish nodes (DTSNS).First of all, the activity regional is divided into grid, to forecast the location of the nodes move next by using the properties of markov. The second, based on the node selfishness its credibility estimation, the purpose is to reduce the communication overhead of the network an...
