Abstract: The mobile ad hoc networks(MANET) are autonomous, infrastructureless network. Unlike the common service discovery used in wired applications, the service applications based on MANET have so many differences in data transmission, service registration and service discovery. All componented of service discovery of MANE T need to consider the features of mobile devices and mobile environment Considering the characters and requiremented, this paper presented a new framework for service discovery in MANET，which supports SOAP-over-UDP and adopts cluster architecture. And to make the service working smoothly in such framework, this paper prompted special service registralion and discovery strategies. The experiment results demonstrate that the new framework with special service working strategies has great superiority both in response-time and efficiency in MANET environment.

Key words: MANET，Service discovery, Fault-tolerant service-matching
