随着物联网（IoT）的出现，越来越多的设备开始交换信息。这把重点放在无线传感器网络（WSNs），以促进在不同的应用场景，例如，建筑和家庭自动化等与环境的交互。在这种情况下，通常需要可靠的通信，即，有必要保证分组在指定的最大延迟或最后期限内到达。此外，由于使用电池驱动的节点和/或为了可持续性，无线传感器网络通常必须节约能源。然而，大多数现有的MAC（媒体访问控制）协议或者不能提供可靠性保证（例如，CSMA）或者它们引起太多的能量消耗（例如，TDMA）。为了克服这个问题，我们提出了一种MAC技术，保证可靠性的要求，同时允许延迟限制和节能的通信。我们进行了大量的实验的基础上详细的模拟与OMNeT++比较建议的MAC，特别是，与CSMA和TDMA，并说明其好处。
With the advent of Internet of Things (loT), an increasing number of devices start exchanging information. This puts emphasis on wireless sensor networks (WSNs) to facilitate the interaction with the environment in varied application scenarios such as, for example, building and home automation among others. In this context, a reliable communication is usually required, i.e., it is necessary to guarantee that packets arrive within a specified maximum delay or deadline. In addition, since battery-driven nodes are used and/or for the sake of sustainability, WSNs often have to economize on energy. However, most existing MAC (Medium Access Control) protocols are either unable to provide guarantees on reliability (e.g., CSMA) or they incur too much energy consumption (e.g., TDMA). To overcome this problem, we propose a MAC technique that guarantees reliability requirements while allowing for delay-bounded and energy-efficient communication. We carry out a large number of experiments based on detailed simulations with OMNeT++ comparing the proposed MAC, in particular, with CSMA and TDMA and illustrating its benefits.
