Fuzzy enhanced secure multicast routing for improving authentication in MANET.

Security is a major concern in mobile ad hoc network (MANET) that ensure packet authentication and integrity. A data transmitted from source to destination node has to be protected from the active and passive attacks. Certificate based secure routing scheme are developed precisely to ensure authentication with certificate mechanism. However, this paper uses fuzzy enhanced secure multicast routing (FSMR) scheme ensure better security in network and data. To estimate the presence of misbehaving nodes, FSMR is established based on normal and abnormal behaviors from the statistical data. Certificateless routing is used in the proposed system and it authenticates the data from the concept of key generation, signcryption and unsigncryption. Packets are routed and validated without the knowledge of certificate routing. The evaluation on proposed system proves that the proposed system has better data packet authentication with lesser energy consumption. Further, the proposed system attains better performance in terms of authenticity, data integrity, network lifetime, average delay and maximum throughput. [ABSTRACT FROM AUTHOR]
