DSDST - A Distributed Service Discovery Approach with Service Type for Mobile Ad Hoc Networks

During recent years Mobile Ad hoc Networks (MANETs) have gained enormous amount of attention and have been widely used. This paper presents a distributed approach for service discovery in MANET, and combines both centralized and decentralized approaches in order to take the best advantages of them. The proposed approach is based on nodes clustering in which every cluster has a head node acting as a centralized directory as well as replies service requests. In our combinatory approach service types are used to enhance service discovery process. Compared to the existing approaches, the proposed approach has the advantage of decreasing the required time for service discovery, and applying less traffic in the network.
