摘要: | 机器对机器 (M2M) 通讯是一种透过各种不同无线技术整合让机器间或是机器跟机器类型通讯 (MTC) 伺服器间能够自动化传送讯息,达到各种不同类别的应用的需求。因为机器对机器通讯能够提供各种自动化完成的应用,并且能够开启新兴市场,因此机器对机器通讯备受众人瞩目。然而机器对机器通讯需要布建大量机器在各个角落,因此带给现今4G网路许多待解的挑战。 在本篇论文中,专注在随机接取控制方面的议题,我们提出了一个能源有效使用的随机接取控制 (energy efficient random access control, E2RAC) 机制,在其中藉由机器数量估计的方式来保证机器有不错的接取品质。因为我们将不同类型的通讯能够使用的接取资源分离,让不同类型的通讯也能够有不同等级的服务品质。模拟结果显示我们提出的能源有效使用的随机接取控制机制能够提供比传统机制更好的服务品质,因此我们的机制更适合应用在未来机器类型通讯的随机接取控制上。 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. |
