一种基于节点主观信任度的分布式多路径路由协议

Distributed Protocol for Multipath Routing Based on Node's Subjective Trust Degree

提出了一种基于节点主观信任度的分布式多路径路由协议(distributed protocol for multipath routing based on node’s subjective trust degree,NSTD-DPMR)。在利用主观信任度对中间节点的恶意程度进行评估的基础上,分布式计算出源端节点发送数据的最佳速率,以及各中间节点的最佳转发速率。仿真实验表明,协议NSTD-DPMR能够在将恶意中间节点对数据传输的危害降低到最低程度的同时,最大化目的端节点接收到的正常数据,保证了路由的安全性和有效性,且协议的复杂度较低。

This paper presents a distributed protocol for multipath routing based on node＇ s subjective trust degree （NSTD-DPMR）. Based on the assessment of middle node＇s subjective trust degree, this protocol computes the best send rate of the source node with distributed method, as well as the best forward rate of the middle nodes. The simulation shows that the protocol NSTD-DPMR will reduce the damage to the data transmission by malicious middle nodes, maximize the right data received by the destination node, and ensure the security and effectiveness of routing with lower complexity.
