摘要: 機器對機器 (M2M) 通訊是一種透過各種不同無線技術整合讓機器間或是機器跟機器類型通訊 (MTC) 伺服器間能夠自動化傳送訊息,達到各種不同類別的應用的需求。因為機器對機器通訊能夠提供各種自動化完成的應用,並且能夠開啟新興市場,因此機器對機器通訊備受眾人矚目。然而機器對機器通訊需要佈建大量機器在各個角落,因此帶給現今4G網路許多待解的挑戰。 在本篇論文中,專注在隨機接取控制方面的議題,我們提出了一個能源有效使用的隨機接取控制 (energy efficient random access control, E2RAC) 機制,在其中藉由機器數量估計的方式來保證機器有不錯的接取品質。因為我們將不同類型的通訊能夠使用的接取資源分離,讓不同類型的通訊也能夠有不同等級的服務品質。模擬結果顯示我們提出的能源有效使用的隨機接取控制機制能夠提供比傳統機制更好的服務品質,因此我們的機制更適合應用在未來機器類型通訊的隨機接取控制上。
Machine-to-machine (M2M) communication is a type of communication. It makes the automatic information exchange between a machine and other machine or a machine and a machine type communication (MTC) server by integrating various wireless communication techniques to satisfy requirements of many applications. Because M2M communication can provide various automatic applications and open a new market, M2M communication is received public attention. But M2M communication needs to deploy a large number of machines everywhere, and bring the current 4G wireless communication system many challenges to be solved. In this thesis, we propose an energy efficient random access control (E2RAC) in which the fine access quality is provided through estimating the number of machines. As we separate access resources for different types of communication, different orders of the service quality can be provided. Simulation results show that the E2RAC scheme provide the better quality of service than the conventional scheme.
