A Secure Mechanism for QoS Routing in Mobile Ad Hoc Networks with QoS Requirements Consideration

Security in mobile ad hoc networks (MANET) Quality of Services routing has received increased attention in recent years. This paper proposes mechanism to obtain secure MANET QoS routing with regard to QoS considerations. Our goal is to present a new mechanism over on-demand multi-path routing protocol (AOMDV) that tackles the twin issues of reliability (protection against failures of multiple paths) and security, while ensuring minimum data redundancy. In addition, we minimize the redundancy using FEC erasure coding techniques and dispersing the original data over the multipath. At last we use hop-by-hop authentication mechanism that prevents some important and known attacks. Simulation results show that our proposed method provides high packet delivery ratio and average call acceptance rate and also has low routing overhead.
