隨著M2M網路的普及與發展，基於M2M網路架構上之應用與服務也隨之快速增加。然而，如何快速而流暢的在M2M網路中傳送封包資訊成為一個重要的議題。在本論文中，我們提出了納入M2M網路應用服務特色的適應性機制。M2M閘道將由M2M節點傳至之資料貯存於緩衝區，並在更新計時器到期時或緩衝區存滿時，將資料匯聚成一新訊息向上傳遞。根據M2M網路應用服務需求，本論文提出了可調整M2M閘道資訊更新速率的機制。我們建立一個在M2M核心網路之適應性延遲更新機制模型，並延伸推導其分析模型。透過調整系統參數，本機制可在M2M核心網路中達到資訊準確率與傳輸能量消耗之平衡與優化。最後，我們透過模擬實驗來驗證本論文之分析模型並描述其機制運作方式。

With the popularity of M2M network, the applications based on M2M network have an exponential growth. How to transmit packets smoothly and effectively in M2M network becomes an important issue. In this thesis, we proposed an adaptive mechanism which takes the characteristics of M2M applications into account. M2M gateway queues the packets from M2M nodes in the buffer and aggregates into one new packet when the update timer reaches the time threshold or the buffer is full. Moreover, we adjust the update rate of M2M gateway according to the M2M application requests. We model the adaptive delayed update mechanism and expand an analytical model on M2M core network. By adjusting system parameters dynamically, the mechanism optimizes the balance between the data validity and the energy consumption on the M2M core network. Finally, we develop a simulation model to validate our proposed analytical model and explain our adaptive mechanism.
