近年來,無線感測網路的應用已經相當普遍,並實際運用在我們的生活上。同時它也是熱門的研究話題,例如網路生命週期、能量消耗、傳輸優先權和碰撞的問題。因此,本論文提出一套動態排程方法以達到感測節點省電的效果,進而增加網路生命週期。首先,提出的網路架構支援數個週期性狀態,決定出感測節點的工作和睡眠的週期時間,此模型適用於以叢集架構為基礎的感測網路。再者,針對叢集內的傳輸排程以傳輸投影距離方法去決定區域性節點的感測資料回傳順序。考慮個別感測節點的能量消耗情況或事件發生機率,我們提出了動態的休眠排程與動態的傳輸排程,能夠延長睡眠時間和改變傳輸順序。最後透過模擬環境來分析整個感測環境,包括了能量消耗、週期性傳輸、活動與睡眠的安排等問題。分析與模擬經驗上的數據顯示出此研究提出的方法是合適且有效率的應用在感測網路上。
In recent years, the applications of wireless sensor networks are already quite general and practical in our daily life. The development of the networks is also a hot topic for researching, and be able to generate many challenges, such as the network life cycle, energy consumption, transmission priorities and collision problems. Therefore, this paper presents a set of scheduling methods in order to achieve energy-saving effect in wireless sensor nodes. First, the proposed network architecture with few cyclic states, dscides sleep/active scheduling that is applied to the cluster-based sensor network. Furthermore, the transmission projection distance determines the returning sequence of sensing data from localized sensor nodes. We provides dynamic sleep and transmission schedulings by computing individual sensor node''s energy consumption and the probability of events happening in localized sensing environments. Finally, we organizes the simulated environment to test the proposed entire network for energy consumption, cyclic transmission, and sleep/active scheduling questions. The simulation results show that the proposed mechanism is energy-efficient transmission in wireless sensor networks.
