Service discovery plays a relevant role in mobile ad hoc environments. Indeed, upon joining a self-organizing network, mobile nodes should be able to explore the environment to learn about, locate, and share the available services. As a result, many researches were performed in this area. Recently, research is being directed towards integrating the service discovery into the routing protocols. This chapter presents the basic concepts of service discovery and their related issues. It also describes the service discovery challenges that arise due to the properties of mobile ad hoc networks. The chapter is concluded by presenting some observations and discussing the current challenges to provide guidelines for possible improvements.

Service Discovery In Manets

The traditional service discovery protocols, which assume a stable network condition, cannot be adapted to the resource-limited and dynamic mobile ad hoc environment. There has been significant research on service discovery solutions for MANETs that take into consideration its infrastructure-less nature (Doval & O’Mahony, 2002; Preu, 2002; Ratsimor et al., 2002; Safa et al., 2007; Artail et al., 2007; Dhanakoti et al., 2005; Helal, 2003). These solutions can be categorized as broadcast-based, advertisement-based, application-based, network-supported, probability-based, semantic routing-based, directory-based, directory less, or a combination of several categories.
