Abstract

Mobile ad hoc networks can be formed by a group of wireless nodes without requiring the use of any preexisting infrastructure. Therefore nodes of such networks can not assume which services exist and where they are hosted. A service discovery protocol that provides automatic discovery of desired services is particularly important to save user from the trouble of configuration and quick access to services. Recently, a service discovery protocol that uses broadcast and introduces the cache function has been proposed. There was a problem of the number of messages increasing with the increase in the number of clients which performs a service discovery request, and becoming the cause of congestion. In this paper, we propose a new service discovery protocol for mobile ad hoc networks, which is characterized by service provision groups and their dynamic reconfiguration for the purpose of reducing the number of control messages, and a simulation study is presented to show the effect of the proposed protocol.
