In this paper, we present RWB, a single-hop broadcast protocol for asynchronous receiver-initiated MAC in WSN, which significantly reduces energy consumption by predicting the receiver’swakeup time and cutting the long back-to-back broadcast into several unicast packets. We have implemented RWB on TinyOS and evaluated its performance on testbeds. The result shows RWB consumes less energy and shortens broadcast period compared to TinyOS’s default MAC while still keeps high delivery ratio.
