The WiseMAC protocol is one of the most energy-efficient medium access control protocols for wireless sensor networks. However, in many typical wireless sensor network scenarios, throughput is limited when high traffic occurs, e.g., if many sensors simultaneously detect and report an event to the base station. The paper proposes to improve the traffic-adaptivity of WiseMAC by extending the more bit mechanism supporting transmissions of frame bursts in WiseMAC. It allows bottleneck nodes to stay awake in situations of high traffic and temporarily abandon the periodic sleep-wake pattern. We evaluate WiseMAC's energy efficiency and compare the original and extended more bit by simulations as well as measurements in a real sensor experiment test-bed.
