Traffic reduction in hybrid service discovery protocol in mobile ad-hoc grid

Service discovery is an important part of nodes communication and collaboration infrastructure in grid computing and the first stage of grid computing scheduling stages. Thus service discovery is very effective in performance and efficiency of grid. Ad hoc grid is one of the earlier distributed systems that combine capabilities of grid computing and flexibility of ad hoc network. Therefore service discovery protocols have an important role in their efficiency. Up to now, many related work to discovery protocol in mobile ad hoc grid have presented that each of them have had advantages and disadvantages. In this paper we try to control query message by caching them into local query control table to decrease network traffic and enhance efficiency of hybrid service discovery protocol. An experimental result shows that we achieve between 10 to 30 percent improvement in our proposed algorithm.
