| 摘 要： | 基于SF数据传输策略和网络编码,提出了一种新的数据传输策略,即SF-NC。SF-NC的基本思想是把消息编码后转发给更有可能与数据汇聚节点通信的传感器节点。SF-NC有Spray和Focus这2个阶段组成,前者完成对冗余数据消息的分发,后者根据不同时刻各传感器节点效用值的大小进行编码数据消息的传输。仿真实验结果表明,SF-NC在提高网络的传输性能上比DTMSN中现有的几种数据传输策略要优越。

| Abstract: | A novel data delivery scheme SF-NC based on SF and network coding is proposed.The main ideal of SF-NC is to forward coding messages to nodes that have higher probability to meet the sink.SF-NC consists Spray and Focus.The former completes the distribution of redundant data messages.The latter make decisions on when to transmit coding data message according to the node utility values.Simulation results show that SF-NC scheme is better than other DTMSN data delivering approaches in improving the network trans... |
