SERVICE COMPOSITION BY USING LOAD AND MOBILITY IN OPPORTUNISTIC NETWORKS

Mobile devices carried by users have the capacity to make use of components in networks that provide services which can be combined to contribute the numerous application level services. As mobile devices are prone to disconnection periodically and partition his result in the necessity of opportunistic networking techniques to communication between the devices. Also this kind of scenarios posses challenges to service composition techniques. There are three phases in our proposed work:1)Selecting suitable set of service sequence;2) routing results of previous node to the next node providing service using multi-hop-path; And result is sent back to the node which is requesting for service. Even though, no direct connections occur between the nodes which are in mobility condition, The nearby services are accessed and given to the user, It can be implemented by combining many services. To combine these services following parameters are considered: “shortest distance”, “load”. Using this information, we estimate the combination of multiple services.
