近年来，低功耗设备的网络越来越受欢迎。通常，这些设备是无线的，并相互作用以形成大型网络，如机器到机器网络、物联网、可穿戴计算和无线传感器网络。这些设备之间的协作是实现这些网络全部潜力的关键。该领域的一个主要问题是在保持整个网络的能量效率的同时，保证网元之间的健壮通信。本文介绍了一种扩展和改进的紧急广播时隙(EBS)方案，该方案便于协作以实现健壮的通信，并且具有能量效率。在EBS中，节点通信单元保持在休眠模式，而唤醒只是为了通信。EBS方案是完全分散的，即节点在每个占空比内以部分重叠的方式协调它们的唤醒窗口，以避免消息冲突。我们给出了该方案的理论收敛行为，并通过真实的试验台实验进行了验证。
In recent years, the networks of low-power devices have gained popularity. Typically, these devices are wireless and interact to form large networks such as the machine to machine networks, Internet of Things, wearable computing, and wireless sensor networks. The collaboration among these devices is a key to achieving the full potential of these networks. A major problem in this field is to guarantee robust communication between elements while keeping the whole network energy efficient. In this paper, we introduce an extended and improved emergent broadcast slot (EBS) scheme, which facilitates collaboration for robust communication and is energy efficient. In the EBS, nodes communication unit remains in sleeping mode and are awake just to communicate. The EBS scheme is fully decentralized, that is, nodes coordinate their wake-up window in a partially overlapped manner within each duty-cycle to avoid message collisions. We show the theoretical convergence behavior of the scheme, which is confirmed through real test-bed experimentation.
