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.
