Wireless Sensor Networks (WSNs) are key for various applications that involve longstanding and low-cost monitoring and actuating. In these applications, sensor nodes use batteries as the exclusive source of energy. Therefore, energy proficiency becomes critical. In this paper, the authors present a novel sleep-scheduling technique called Virtual Backbone Scheduling (VBS). VBS forms multiple overlapped backbones which work alternatively to elongate the network lifetime. In VBS, traffic is only forwarded by backbone sensor nodes and the rest of the sensor nodes turn off their radios to save energy.
