An Energy-Efficient and Low-Latency MAC Protocol in Smart Grid (SG-MAC)

Abstract

Abstract-In this paper we propose a new protocol -named-SGMAC for reducing the energy consumption and shortening the time of data sending in smart grid to control media Access. This protocol uses sleeping and waking intervals distinct in the same duty cycle and the sender node will participate only in the period of receiving node over the ownership of the channel.Furthermore, we have compared the proposed protocol from the point of view of energy and delay with IEEE802.11 and SMAC in two different protocol topologies. In the simulation results illustrated that SG-MAC protocol using data gathering tree and apply collection sleep and waking intervals, less delay in comparison with the SMAC protocol and much less energy consumption in comparison with the IEEE802.11.
