The Researches On Service Discovery Architectures And Protocols In The Future Networks

With the development of mobile communications technologies and the growing popularity of network-based applications, Service Discovery (SD), which is needed for quickly locating resource providers, has been the necessity functions in the future networks.We have surveyed most mature and well-known service discovery architecture or protocols currently. The researches on them have been done, so some problems are found in current service discovery fields. We hope there exists a novel service discovery architecture that can be used in future global, converged networks to adapt the dynamic, inhomogeneous environments. In this paper, we propose three different service discovery architectures based on distinct future environments, which are the hot research topics.According to the features on Personal Networks (PNs), we design a system, which achieves the process of SD in PNs with a modified version of Intentional Naming System. According to different environments, we classify the process of SD into three cases to simplify the whole process in PNs. Furthermore, we consider the ambient information around the services, which is obtained by the process of context discovery. It is important to find and choose the most suitable service for clients. We also make some contributions to the combination of SD in application layer and some mechanisms in network layer. Therefore, in our proposed architecture, the most suitable service for clients' applications can be found within a short period of time and the overhead of SD in PNs will be obviously decreased.Secondly, we proposed a novel SD architecture, TriD, which uses a...
