| Summary: | 碩士 === 國立成功大學 === 電腦與通信工程研究所 === 100 === 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.
