Unreliable Node Detection by Elliptical Curve Diffe-Hellman Algorithm in MANET

Objective: The purpose of this scheme is to detect unreliable node from routing and provide reliable data transmission in MANET. Method: The openness in network topology and deficiency of the central administration leads to vulnerable attack in MANET. In order to decrease the threat in Mobile Ad-hoc Network (MANET), we propose Unreliable node Detection by Elliptical Curve Diffe-Hellman in MANET (UD-ECDH). Findings: The UD-ECDH scheme exchanges the secret key to detect the unreliable node and isolate from routing thus increasing the network performance. Improvement: The simulation results show that this scheme assure better packet delivery, improve throughput, reduces the delay and energy consumption in the network.
