ABSTRACT

Several routing protocols have been proposed in recent years for possible deployment of Mobile Ad hoc Networks (MANETs) in military, government and commercial applications. Secure ad hoc networks are expected to meet five security requirements: confidentiality, integrity, authentication, non-repudiation and availability. Routing Algorithm that integrates security and performance requirements are considered to be more advantage. The SRAC protocol optimizes a combined objective function of security and performance parameters. However, the destination wait- time for decision on route selection and TrustworthinessñQoS index calculation at each node add up for delay. The use of two different routes and synchronization in the packets results with additional overhead. In this paper, an effective solution that overcomes the cons of SRAC is proposed with same security and better QoS can be achieved.
