Fuzzy rule-based approach for design and analysis of a Trust-based Secure Routing Protocol for MANETs

Abstract The paper proposes a fuzzy rule-based approach for design and analysis of a Trust-Based Secure Routing Protocol for MANETs (TBSRPM). Due to highly dynamic behaviour of nodes the shortest route does not necessarily guarantee a secure route. Hence stability of route is not taken into consideration as the route can be easily break in the dynamic MANETs. Thus finding a stable and trusted route is of great importance. The proposed algorithm is the extension of the existing reactive routing protocol (AODV), developed for creating secure route between sources to destination. The protocol behaviour depends on TV and LOT as well as TV decides what level of security action is required. So based on TV, the data packet is encrypted. With the help of TV, malicious nodes can be easily eliminated and we can establish a best trusted route as well. Results show that the proposed TBSRP enhances MANETs.
