An adaptive fuzzy logic based secure routing protocol in mobile ad hoc networks

In ad hoc networks, designing a secure routing protocol is critical. The FLSL (Fuzzy Logic Based Security-Level Routing Protocol) routing protocol is proposed in this paper. The basic idea of FLSL is to utilize the “local multicast” mechanism and the Security-Level to select the highest Security-Level route. The proposed algorithm of Security-Level is an adaptive fuzzy logic based algorithm that can adapt itself with the dynamic conditions of mobile hosts. Simulations show that the FLSL routing protocol can improve security of mobile ad hoc networks. The FLSL routing protocol is feasible to the weak security character of MANETs (mobile ad hoc networks).
