: Ad hoc networks are networks that consist of wireless mobile nodes. They are networks that do not require any preestablished infrastructure. Their ability to quickly and dynamically provide a means of communication makes them an adequate choice for many types of applications both in civil, industrial and military fields. The mobility and the autonomy of ad hoc nodes require a mechanism for service discovery, which allow to provide mobile nodes with information about the services offered in the network. In this paper, we focus on a strategy for services discovery and publication coupled with ad-hoc routing. We propose a new protocol for services discovery called SEDIRAN (Service Discovery and Interaction with Routing protocols in Ad hoc Network), on top of a reactive routing protocol, namely, AODV (Ad hoc On demand Distance Vector). However, we think that our protocol can be easily generalized to other reactive routing protocols.
