One of the core features of IoT is global device discovery, allowing people to control and manage their connected devices anywhere across the internet. In pervasive IoT, device management becomes seamless and automated using AI for device pairing, content discovery, actions signaling, and command scheduling based on contextual information in a self-managed device paradigm. This chapter presents a novel handoff technique for smart speakers to ensure playback continuity when the users move around in a smart space consisting of multiple discoverable speakers. Current implementations include Spotify Connect, which is service specific, thus lacking in discovery robustness. The proposed handoff discovers at the device level instead of service level to improve device visibility and interoperability through a self-learning topology discovery (SLTD) method. For timely handoff, a rapid preemptive handoff method (RPF) is designed to optimize the TCP handshake mechanism and a content pre-caching technique is used to minimize playback gaps during the soft handoff.
