Energy efficiency is a major concern in the design of Wireless Sensor Networks (WSNs) and their communication protocols. As the radio transceiver typically accounts for a major portion of a WSN node's power consumption, researchers have proposed Energy-Efficient Medium Access protocols that switch the radio transceiver o for a major part of the time. Such protocols typically trade off energy-efficiency versus classical quality of service parameters (throughput, latency, and reliability). Today's Energy-Efficient Medium Access protocols are able to deliver little amounts of data with a low energy footprint, but introduce severe restrictions with respect to throughput and latency. Regrettably, they yet fail to adapt to varying traffic load at run-time.
