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

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.
