Performance of Comparison between AODV and Secured Protocol

In mobile ad hoc networks packets are relayed over multiple hops to reach their destination. Due to the features of open medium, dynamic topology, cooperative algorithms, lack of centralized monitoring and management point mobile ad-hoc networks are much more vulnerable to security attacks when compared to the wired networks. A number of secure routing schemes have been brought forward. However, existing anonymous routing protocols mainly consider anonymity and partial unlinkability in MANET. Complete unlinkability and unobservability are not guaranteed due to incomplete content protection. The main objective of the project is to provide an anonymous routing and secure communications in mobile ad hoc networks. Therefore a new on demand routing protocol called Unobservable Secure On demand Routing protocol (USOR) is proposed to offer complete unlinkability and content unobservability for all types of packets. USOR is efficient as it uses a novel combination of group signature and ID-based encryption for route discovery. Security analysis demonstrates that USOR can well protect user privacy against both inside and outside attackers. USOR is implemented by using ns2, and evaluate its performance by comparing with AODV.
