A secure service discovery protocol for MANET

Service discovery technologies are exploited to enable services to advertise their existence in a dynamic way, and can be discovered, configured and used by other devices with minimum manual efforts. It plays an essential role in future network scenarios especially with development of mobile ad hoc network (MANET) and emergence of pervasive computing. Because MANET allows these devices to communicate dynamically without fixed infrastructure and centralized administration, it gives rise to the challenges of the service discovery techniques. In this paper, we present a dynamic service discovery infrastructure that uses XML to describe services and match using the semantic content of service descriptions for MANET. We believe that the architecture we have designed is a necessary component of service discovery in non-infrastructure network by further exploring the secure and performance issues of this infrastructure.
