in MANETS as the nodes are not static and are not available all the times still the Composite service provision become a great challenge and its success rate is not satisfactory In mobile ad hoc networks, usually Composite service is achieved through the service composition . the main reason for the fall of the success rate of service composition is involving more number of nodes and the node's failure probability is proportional to the length of time the node exist in the networks. In this

... r in order to improve the success rate of service composition we are suggesting several measures. First, we split the service requirement into several segments and cluster the nodes, so that the nodes' waiting time for service composition can be reduced. Second, we propose a new node model of "one node contains multiple services" in mobile ad hoc networks. Using this type of nodes model, the number of nodes required for service composition can be reduced. These means can increase the success rate of service composition.
