A Proposed Security Subsystem for Ad Hoc Wireless Networks

Ad hoc networks are a new generation of networks offering unrestricted mobility without any underlying infrastructure. Due to lack of centralized control, secured communication in mobile ad hoc network is a crucial issue due to dynamic nature of the network topology. While the routing aspects of mobile ad hoc networks (MANETs) are already well understood, the research activities about security in MANETs are still at their beginning. MANETs pose a number of new security problems in addition to the problems of regular networks. In this paper, we propose an effective security AODV algorithm called ES-AODV to enhance the data security. Simulation results show that our algorithm provides a reasonably good level of security and performance.
