An Empirical Study on Interoperability between Service Discovery Protocols

Service discovery protocol (SDP) is one of the fundamental infrastructures in pervasive computing. However, various SDPs differ on service description model, system architecture, deployment network and service discovery mechanism. It is highly necessary to develop a framework that can provide interoperability for multiple SDPs. In this paper, we carry out an empirical study on building a novel interoperable framework called Service CatlogNet Interoperable Framework (SCNIF), focusing on the interoperability evaluation including the completeness, the extensibility, the transparency and the overhead. Although the empirical study is based on SCNIF, we believe the results are valuable to most interoperable frameworks because SCNIF compromises many interoperability techniques and has successfully developed plug-ins for many SDPs and legacy systems.
