Fuzzy based Combined Trust Scheme for Secure Routing in MANET (FCTRS)

Abstract

Mobile Ad Hoc network (MANET) is a self-configuring network consisting of mobile nodes without any fixed infrastructure. However due to the nodes has not any fixed infrastructure in MANET, it is susceptible to various security attacks like data modification, information sniff, due to low energy, computing ability and bandwidth. In MANET Black hole is also an attack and it is difficult to detect and prevent. The lack of quality in security aspects of ad-hoc routing protocols won’t provide reliability in the data packets movement between source and destination nodes. Implementing the routing decision with trust is an important one in the MANNET security. Hence, this research work propose an enhanced Fuzzy based combined trust scheme (FCTRS) based on public trust and Quality of Service (QoS) trust to detect black hole attack. It provides secure routing based on certificate authority (CA) to improve the performance of Ad-hoc On-demand Distance Vector (AODV). The results will show the performance improvement of proposed protocol over Enhanced Trusted Routing Scheme with Pattern Discovery (ETRS-PD) and the protocol AODV. The metrics in the performance of network examined with different conditions of mobility and the presence of black hole node positions.
