Abstract: In order to comprehend the service discovery protocols better, this paper proposes several criterions about service discovery protocol in pervasive computing environments, and compares a few service discovery protocols based on different architectures in different environments and categorized in terms of network type and storage mode of service information. The five service discovery protocols in wireless Ad hoc network are introduced, and their characteristics and performances are compared and analyzed.

Key words: pervasive computing, wireless Ad hoc network, service discovery, service information storage
