Security Routing Protocol Resisting Blackhole Attack in Delay-tolerant Sensor Network
S Chen · Jisuanji gongcheng · 2014
Delay-tolerant Network(DTN)is an Ad Hoc network,in which there is not end-to-end path between the source and the destination nodes in most of the time,and DTN relies on the mechanism of store and forwards to realize the asynchronous communication. Aiming at the blackhole attack in DTN,this paper proposes a security routing protocol which can detect blackhole nodes. It analyzes the model of DTN,gives a scheme to detect malicious nodes,and merges this scheme with the routing protocol. Compared with existing routing protocols through the simulation,it verifies that the security routing protocol can accurately detect the malicious nodes and it has better performance in DTN environment.When being used in water environment monitoring or city traffic control and other fields,the security routing protocol can avoid the network environment from malicious nodes attack,and ensure the reliability and stability of network.
