An integration of distributed service discovery with routing protocols for MANETs

In this paper, we propose SDRP: a new service discovery protocol combined with routing policies in MANETs. It performs the protocol acting upon a backbone and access network as well as any kind of distributed networks. We describe a service by a unique ID number and use a group-cast routing policy in advertising and requesting. In addition, the nodes in the reply path also cache the advertisement information. We compare SDRP with Flood and AODV in terms of overload, demand throughput and average delay. Simulation results show SDRP can save response time and accommodate even high mobility network environments
