Secure Routing Protocol in Delay Tolerant Networks Using Fuzzy Logic Algorithm

S. Karthika, N. Vanitha

Security is the biggest challenge in MANET. MANET presents various types of security attacks on data exchanges taking place between source and destination. In this misbehavior detection schemes for conventional wireless networks has opposed black hole attack and malicious node occur routing, this proposed technique as a great challenges in networks. In this iTrust, a probabilistic misbehavior detection scheme is highly desirable to assure the secure DTN routing as well as the establishment of the trust, among DTN nodes. A zone (routing zone) of a node is used to collect the node information within the range. In this protocol, it cannot achieve the packet delivery ratio, performance and data loss rate. In this paper we are providing the solution against black hole attack which is based on fuzzy rule. Fuzzy rule is used to identify the infected node as well as provide the solution to reduce data loss over network. Fuzzy logic ranges between the value as {0, 1}. Geographic routing is one of the most suitable routing strategies in wireless mobile Adhoc network mainly due to its scalability. Multi Input Multi Output technique used to send data frequently in routing protocol. Analysis and simulation results demonstrate the effectiveness and efficiency of the drop node analysis, high packet delivery ratio, throughput and delay.
