Service discovery, which is an important required function for service-based systems (SBS), affects the performance of SBS, especially in pervasive service computing environments. In this paper, an efficient approach to service discovery in multi-hop pervasive service computing environments is presented. This approach is situation-aware and based on group-based service discovery protocol. In a pervasive computing environment, the situation, including available service resources, users’ preferences and the physical environment, changes more dynamically. Our service discovery approach exploits the network asymmetry and incorporates situational information while keeping low network overhead. Our simulation results show that our approach discovers services efficiently.
