Mobile Ad hoc Networks (MANETs) are wireless networks having transient mobile nodes with no pre-installed infrastructure. They are of utmost interest for the future networks owing to their flexibility, effortlessness of deployment and related low cost. Most of the research problems of mobile ad hoc networks are stems from mobile computing. The constraints like resource-poor elements and their limitations, gives rise to many research problems. Among them, the research issue, service provisioning for application development by the concept of reusing is of high importance. Services are hardware or software entities that can be shared or reused by many other software entities. One of the main uses of mobile ad hoc networks is accessing the services that are provided by other nodes where ever possible. This reuse of services is predominantly used in fixed networks. The process used to realise the reusing of services is termed as service provisioning. The service provisioning is used to describe the process starting form service selection, service binding service maintenance and termination. Because of their dynamic nature, service provisioning in mobile ad hoc networks should have different components compared to that of fixed networks. This thesis focuses on finding the essential new components, or modifications to be done in the existing components to enable service provisioning in mobile ad hoc networks. In fixed networks reusing of services is done by Service Oriented Architecture. Service Oriented Architecture (SOA) is an architectural paradigm and discipline that may be used to build infrastructures enabling the interaction of those with needs and those with capabilities via services. In SOA the service providers will advertise their capabilities, which are stored in the central entity namely service broker. The service capability information includes both functional and non-functional properties. Whenever a client needs a service, the requester's requirements will be compared with the service capabilities. If they found a matching service provider they can access the service.
