QoS Aware Trusted Service Discovery Architecture for Optimization in MANETs

During service discovery architecture designing in MANET, some of the critical services requested by the clients should be provided within short deadlines. Moreover, the QoS constraints of the service providersuch as; battery power, stability, trust, load, capacity, etc., should also be considered while selecting the servers. In this QoS aware trusted service discovery architecture, a set of backbone nodes are selected based on the relative mobility, residual energy and available bandwidth. The selected backbone node collects the information related to server and its services. When the service is availed by a client, the backbone node then updates the trust value of that server. By simulation results, we show that the proposed technique enhances quality of services through minimizing the delay.
