The medium access control (MAC) protocol determines the energy consumption of a wireless sensor node by specifying the listening, transmitting or sleeping time. Therefore MAC protocols play an important role in minimizing the overall energy consumption in a typical wireless sensor network (WSN). Using transmitted reference (TR) modulation in the underlying physical layer opens up new possibilities and challenges to be investigated in the upper MAC layer. Hence this paper presents a new energy-efficient MAC protocol, called TR-MAC, to exploit all the benefits provided by the TR modulation in the physical layer while minimizing the drawbacks. TR-MAC enables both transmitter-driven and receiver-driven communication in the WSN, allows a pair of nodes to use individual frequency offsets for multiple access, and is capable of achieving fast synchronization in the receiver to reduce energy consumption. In short, TR-MAC is an energy-driven MAC layer communication protocol for asynchronous low data rate applications that enables nodes to adapt their duty cycle based on the available energy in the node.
