A cluster based QoS-aware service discovery architecture for mobile ad hoc networks

The existing mobile service discovery approaches do not completely address the issues of service selection and the robustness faced to mobility. The infrastructure of mobile service must be QoS-aware plus context-aware (i.e.) aware of the user´s required-QoS and the QoS offered by the other networks in user´s context. In this paper, we propose a cluster based QoS-aware service discovery architecture using swarm intelligence. Swarm intelligence is used to establish the intra and inter cluster shortest path routing. By simulation results, we show that the proposed architecture can attain a good success rate with reduced delay and energy consumption, since it satisfies the QoS constraints.
