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. Index Terms-Smart grid (SG), medium channel access control (MAC), sensor-MAC (S-MAC), request to send (RTS), clear to send (CTS).
Abstract-Today by more complicating in smart grid, request and need for reliability, security and more efficiency and also environmental concerns, we need to change the operation and use of electrical networks. Power companies and the government consider that the smart grid will be salvation for the future. Recent advances in the fabrication of integrated circuits and the development of wireless communication technology that is cusses WSN entry in smart grid. One of the most important features of sensor networks used in smart grid is the energy constraints. So we will offer a new architecture for smart grid in the field of the WSNs to reduce the total energy. Moreover, we will improve some routing factors, QoS parameters such as delay and reliability with respect to the desired user.Index Terms-Smart grid, wireless sensor network, sectoring, minimum spanning tree.
