低功耗无线传感器网络（WSNs）技术需要变得更加灵活，以满足新兴的数据驱动的应用和物联网。例如，无线传感器网络需要超越传统的多对一的数据收集流量模型，并开始支持多播通信。然而，在无线传感器网络中，有效的组播是具有挑战性的。在本文中，我们提出了应用机会转发的概念来创建一个机会组播框架的责任循环的无线传感器网络。我们的框架允许任何节点直接和有效地组播到已知的潜在目的地的任何子集。我们提出了几个变化的计划在这个框架内运作。我们评估我们的框架和建议的计划，使用模拟。
The technology of low-power wireless sensor networks (WSNs) needs to become more flexible to cater to emerging data-driven applications and the Internet of Things. For example, WSNs need to look beyond the traditional many-to-one data collection traffic model and begin to support multicast communications. However, efficient multicasting in WSNs is challenging. In this paper, we propose to apply the concept of opportunistic forwarding to create an opportunistic multicast framework for duty-cycled WSNs. Our framework allows for any node to directly and efficiently multicast to any subset of known potential destinations. We propose several variations of schemes to operate within this framework. We evaluate our framework and the proposed schemes using simulations.
