The Gridlock Robust Medium Access Control (GRMAC) is introduced in wireless sensor networks for collision-free channel access. GRMAC decreases the consumption of energy by allowing low-power and idle state to nodes whenever they are free i.e. neither transmitting nor receiving which ensures that all transmissions have no collisions including broadcast, unicast and multicast. GRMAC uses a time slot and a distribution election scheme which contains the information about the traffic at each node to find out which node can transmit at a particular time slot.
