Service discovery for wireless ad hoc networks

Multi hop wireless ad hoc networks can be formed by a group of wireless nodes without requiring the use of a preexisting infrastructure. However such an ad hoc network environment is hard to administer, so applications cannot assume they know which services exist and where they are hosted. A service discovery that provides automatic discovery of desired services to the applications is particularly important to save the user from the trouble of configuring tasks and has the advantage of a full range of provided services. In this paper, we propose a new service discovery method for multi hop wireless ad hoc networks. The method provides an efficient method of service discovery for increasing the number of discoverable services. We evaluate the proposed method through a simulation study and compare it with the existing method. Results show that the proposed method achieves better performance in terms of the number of discoverable services, while the number of control messages and response time for discovering the services are almost the same as the existing method.
