A Secure AODV Routing Scheme with Reduced Data Packet Delay in MANET

Abstract

Among the various security mechanisms that has been proposed for Ad hoc On-Demand Distance Vector (AODV) routing protocol, the secure extension of AODV (SAODV) is most popular and efficient. Since SAODV based on digital signature mechanism for authenticating routing packet of AODV, it consumes heavy computation time while generating and verifying a signature. The condition becomes worse for an intermediate node in ad hoc network and in turns degrades the performance. Adaptive-SAODV mechanism is a step towards enhancing the performance with respect to data packet delay of a node in the above mentioned scenario. In this paper we have proposed an algorithm that based on the adaptive decision of an intermediate node that depends on its load state of current node and neighbors. The performance of the proposed algorithm with A-SAODV and SAODV has been presented with data packet delay and throughput as metric.
