Current trends suggest that the smart home systems should be adaptive and robust. Many service-oriented architectures and discovery protocols for the smart home environments have been proposed to support on-line re-composition of home services in reaction to changing environments. Nevertheless, few researches have been done to improve the robustness of smart home systems. This paper attempts to propose a service management protocol that supports fast self-healing and self-organizing of home services by enhancing SSDP/UPnP with two protocol extensions and a lightweight heartbeat mechanism. Experiment results show that for average scale of services (less than 10 service components), the proposed protocol is capable of activating a service and recovering a failed service within 1200 ms and 2000 ms, respectively.
