Performance Comparison of the AODV, SAODV and FLSL Routing Protocols in Mobile Ad Hoc Networks

Mobile ad-hoc networks operate in the absence of any supporting infrastructure. The absence of any fixed infrastructure in mobile ad-hoc networks makes it dif-ficult to utilize the existing techniques for network ser-vices, and poses number of various challenges in the area. The discovery and maintenance of secure route is the most flinty challenge. In this paper, we first deliberate and implement one secure routing protocol FLSL (Adaptive Fuzzy Logic Based Security Level Routing Protocol) and study its performance under different scenarios. Then we carry out a number of experiments using NS-2 to compare the performance of AODV, SAODV and FLSL in terms of security level and routing discovery time under different setups. From these experiments, we can see that FLSL outperforms than AODV and SAODV. 1
