智慧型家庭照明環境是無線感測網路與嵌入式照明系統的結合，並進行一連串位置感知(Location Aware) 觸發控制之行為，以實現自動化照明服務之情境，其以人為本的服務內容是智慧環境(Ambient Intelligence) 的應用發展之一。智慧型家庭照明環境所提供服務主要之目的在於增進使用者居家生活品質的提升，而提供的服務必須要適時、適地才不致讓使用者感覺到困擾。本論文利用無線接收信號強度(Received Signal Strength, RSS) 之定位法則並以ZigBee無線感測網路為基礎架構，實作出智慧型家庭照明情境的應用服務，並可以依照不同家庭成員在特定的地方會有不同亮度之情境需求，進一步實作相對應的燈光強度控制，以提供使用者視覺多元化的照明感受環境。
本論文亦探討影響無線感測網路能源消耗、封包碰撞與接收訊號強度等相關之因素。在無線網路的傳輸過程中若無法有效地避免封包碰撞情況的發生，將會影響到資料接收時間的延遲，進而影響到系統的整體服務效能。因此本論文提出訊號強度多工存取/碰撞避免(Radio Signal Strength Division Multiple Access/Collision Avoid , RSSDMA/CA) 的機制，以改善因封包碰撞所衍生系統運作效能降低情況的發生。經由實際所接收之訊號強度數據封包的實驗結果，證明RSSDMA/CA機制在高傳輸流量的無線感測網路環境下，確實可以有效改善CSMA/CA機制在無線感測網路下封包碰撞之情況的發生，達到智慧型家庭照明環境服務效能提升與系統穩定之目標。

The Smart Home Lighting Environment is one application of ambient intelligence, which is the combination of wireless sensor networks and lighting with embedded behavior controlling functions triggered by location aware signals to accomplish the scenario of automatic lighting services. The main purpose of smart home lighting environment is to help provide comfort life for family members. Therefore, the services should be provided at right time, right place and without being felt annoyed by users. This thesis adopts the Received Signal Strength (RSS) techniques and ZigBee wireless sensor network to implement the application services of smart home lighting environment. It provides family members with different light brightness according to their presences at the particular time and in the particular place. Furthermore, it can be integrated into related services of ambient intelligence to achieve an intelligent and friendly living environment.
Being aware of the factors that affect the energy consuming, package collisions, and received signal strength on wireless sensor network, this thesis also studies the issue of collision with package during the transmission process over wireless networks, which imposes performance impact upon the wireless sensor networks not only in the aspect of operation but also in the aspect of power consumption. To address the above issue, the mechanism of Radio Signal Strength Division Multiple Access/Collision Avoid (RSSDMA/CA) is proposed to reduce the demotion of efficiency in system operation incurred from package collisions. The RSSDMA/CA mechanism is extended from CSMA/CA (Carrie Sense Multiple Access/Collision Avoid). It works by determining package transmission route from a node based on the received signal strength (RSS) upon joining the network. From the results of experiments on collisions of package transmission, it can be observed that the RSSDMA/CA mechanism can effectively avoid the collision of packages under high transmission flow and operates with more efficiency than the commonly used CSMA/CA mechanism. It therefore helps to achieve the goal of stabilizing operation and of improving the performance of smart home lighting environment.
