智慧家庭環境是一個典型的分散式系統，在此類環境中的智慧服務大都由一至多個節點組成，例如一個智慧空調服務需要冷氣機、溫度感測器和邏輯判斷節點。然而，只要服務其中一個節點故障，整個服務就無法正常運作。由於居住在家庭中的大都是不具技術能力的使用者，故理想的智慧家庭服務，即使在有節點故障的狀況下，也應能在短時間內盡可能自動偵測與排除錯誤，使服務的運作不被中斷。本研究主要目的在於提出一個智慧家庭的強健服務管理系統，基於創新的複合式架構，結合集中式與非集中式錯誤偵測機制的特色，能在短時間內偵測到節點失效，進而恢復由於軟體所造成的節點故障或尋找待用節點，使得服務能繼續運行。 / Smart home systems are different from traditional computing systems. In a smart home system, a service is composed of several service nodes. For example, a smart air conditioning service needs a temperature sensor, an application logic, and an air conditioner. A service fails if one of its affiliating nodes fails. However, unexpected failures are undesirable for mission critical services such as healthcare or surveillance. Moreover, a smart home lacks professional system administrators. Users are generally unable to repair a service when it fails. Consequently, in a smart home system, the failed services have to be diagnosed and recovered automatically. In this paper describes a hybrid failure detection and recovery method for smart home environments. Experiments show that the proposed architecture is able to enhance overall availability of a smart home system in a short time.
