Secure enhancement scheme for detecting selfish nodes in MANET

Mobile Ad hoc Networks (MANETs) operates on basic underlying assumption where all participating nodes are fully collaborated in self-organizing functions. However, performing network functions consumes energy and other resources. Therefore, some network nodes may decide against cooperating with others. The selfish nodes, also termed as misbehaving nodes, with an incentive to cooperate has been an active research area recently. In this paper consider 2ACK scheme, which can be simply add-on to any source routing protocol. Security is achieved through the use of cryptographic algorithms. In this work, we perform an analysis of the energy requirements of various cryptographic primitives with the intention of using this data as a foundation for devising energy-efficient security protocols also we measure on delay, packet delivery ratio and routing overhead to evaluate best security algorithm.
