A Secure Route Discovery Protocol for AODV Based Mobile Adhoc Networks Using Hyperelliptic Curve Cryptography

A Mobile Adhoc Network (MANET) consists of numerous number of nodes, neighbor nodes are connected by means of radio links. Each node is constrained with limited power, bandwidth and scalability. Many researchers lay their effort to develop various techniques for providing a secure route in MANET. As a result, an Elliptic Curve Cryptography (ECC) technique is used to develop a secure shortest algorithm for routing the packet from source node to destination node, since ECC is famous due to its shorter key length and less computational overhead for encryption and decryption operation. ECC is more suitable for power constrained devices. But ECC based secure routing protocol requires a large number of Route Request (RREQ) packet in Adhoc on Demand Distance Vector (AODV) protocol and consumes more power. In order to reduce the number of RREQ packet and power consumption, a proposed secure energy efficient routing protocol is implemented. Finally, discuss the improvement of the proposed approach with the existing systems using GloMoSim software tool.
