Integration of Cluster based routing and Mobile Service Discovery Protocol for MANETs: A Novel Approach

-Service discovery technologies enable services to advertise their existence in a dynamic way, and can be discovered, configured and used by other devices with minimum manual efforts.In order to achieve efficient service discovery in large scale Mobile Ad hoc Networks (MANETs) we have proposed a scheme that integrates service discovery with cluster based routing by piggybacking service information into routing layer messages. Thus, service discovery does not generate additional messages and a node requesting a service, in addition to discovering that service; it is simultaneously informed of the route to the service provider. The proposed Service Discovery Protocol uses a dynamic clustering algorithm to group nodes in a MANET into clusters, and utilizes Distributed Hash Tables (DHTs) called Service Table to efficiently cache service information in a peer-to-peer manner. This paper proposes a scheme that greatly enhances service discovery in terms of efficiency, minimizes the traffic and energy consumption.
