Design and Verification of Communication Protocols for Peer-to-Peer Multimedia Systems

This paper addresses issues pertaining to the necessity of utilizing formal verification methods in the design of protocols for peer-to-peer multimedia systems. These systems require sophisticated communication protocols, and these protocols require verification. We discuss two sample protocols designed for two distinct peer-to-peer computer vision applications, namely multi-object multi-camera tracking and distributed gesture recognition. We present simulation and verification results for these protocols, obtained by using the SPIN verification tool, and discuss the importance of verifying the protocols used in peer-to-peer multimedia systems
