Title: TR-MAC: An energy-efficient MAC protocol exploiting transmitted reference modulation for wireless sensor networks.
The Medium Access Control (MAC) protocol has a direct effect on energy efficiency of the wireless sensor network (WSN) since the MAC protocol delineates the access to the shared medium and decides about the duty cycle of the sensor node. We proposed an energy-efficient MAC protocol named TR-MAC that exploits transmitted reference modulation in the underlying physical layer. TR-MAC is an energy-driven MAC protocol that enables both transmitter-driven and receiver-driven communication in the WSN where one node having less energy can transfer the communication burden to the other node depending on the locally available energy. TR-MAC ensures energy-efficiency as nodes can adapt their duty cycle based on the packet arrival rate.
