A Secure Path Selection Scheme for Mobile Ad Hoc Network

Mobile ad hoc network is open medium, infrastructure-less and easy to install. Despite these features, mobile ad hoc network is vulnerable to various security attacks. Black hole and gray hole security attacks outrank among all security attacks. This paper proposes a distributed delegation-based scheme, namely, a secure path selection scheme. The proposed scheme identifies and allows only trusted nodes to become part of active path. The simulation results revealed that proposed scheme improved the packet delivery ratio, packet loss rate, throughput by 8% and routing overhead by 5% as compared to other system.
