A technique able to significantly reduce the energy consumption of contention-based MAC protocols for wireless sensor networks is presented. Address and timing information is embedded into the packet preamble, allowing receivers to power off their radio during part of the transmission. Analytical and experimental evaluations show a significant extension of the network lifetime.
