Broadcast is a fundamental operation in Wireless Sensor Networks (WSNs). Given a source node with a packet to broadcast, the aim is to propagate the packet to all nodes in an interference-free manner whilst incurring minimum latency. This problem, called Minimum Latency Broadcast Scheduling (MLBS), has been studied extensively in wireless ad-hoc networks, whereby nodes remain on all the time, and has been shown to be NP-hard. However, only a few studies have addressed this problem in the context of duty-cycled WSNs. In these WSNs, nodes do not wake-up simultaneously, and hence, not all neighbors of a transmitting node will …
