传感网中多路径Sink节点隐私保护方案的改进

Improvement of Privacy Protection Scheme of Sink Node in Sensor Network,Multiple Paths

针对原方案中第一个交叉结点发送假包而不考虑该节点处真实数据流量的问题,提出在第一个交叉结点处进行流量监控,并根据监控的真实数据流量值来决定发往每个假的Sink节点的假包量的方案,并且假包概率传输的同时,当假包传输跳数大于真实数据包到达Sink节点跳数时,就自动丢弃。实验结果表明,网络数据传输的安全时间有了明显提高,但是需要牺牲少许网络能量开销。

aiming at the first intersection nodes in the original plan send fake bag without considering the node real data traffic problems, a traffic monitoring is presented at the first intersection node, depending on the real data traffic monitoring to determine to every false package amount of Sink nodes, and false probability of packet transmission at the same time, when the false packet transmission hop count is greater than the actual packet arrived at the Sink node hop, is automatically discarded. The experimental results show that the safety of the network data transmission time has obviously impwved, but need to sacrifice a little network energy costs.
