Providing Security Towards the MANETs Based on Chaotic Maps and Its Performance

摘要

Mobile ad hoc network (MANET) consists of mobile nodes that communicate with one another through radio communication channel. This wireless channel is vulnerable to security attacks. Thus, MANET needs a perfect security mechanism to secure network from security attacks. In literature, different security mechanisms have been designed to solve the security issues via cryptographic techniques. Security mechanisms should not cause overhead to MANET in terms of computation and storage, as this network is resource constrained. Thus, in this work, we compare the performance of cryptographic solutions that designed for MANET based on RSA and Chaotic maps. Performance results show that RSA is one of the best cryptographic algorithms to provide security, but its time complexity is more than the Chaotic Maps-based cryptography technique. Moreover, time complexity causes a negative impact on overall network performance; particularly end-to-end delay. We conclude from our work, Chaotic Maps-based cryptographic technique is well alternative to RSA, with less overhead and appropriate security.
