Hybrid service discovery is introduced as an efficient service discovery protocol in mobile ad-hoc grid witch has a good compromise between response time and network traffic overhead. In this paper we modify the basic idea of this protocol called Zone. We use multi-level zone in our proposal and called the protocol as multi-level hybrid service discovery protocol. Our algorithm tries to provide the advantage of larger zone with only a little increase of network traffic overhead. We used two levels of zone, inner zone and outer zone which we called internal zone and external zone, respectively. Difference between two zones issued from their advertisement frequency. Simulation results show that our proposed algorithm has better performance in network's traffic and response time than traditional hybrid service discovery protocol.
