In the data communication era, smart grid is visualized as decisive application for internet related applications and networking systems. To integrate the physical environment with the data communication applications, wireless sensors are required. In the wireless sensor based smart gird applications, load balancing and power quality measurements are predicted as major factors for better performance. In wireless network architecture involving smart grids, the deployment of the sensor nodes and the conservation of the residual energy are the two primary problems which attract research interest. Thereby analysis of the performance metrics based on the sensor node deployment and the energy conservation in the smart grids becomes important. In this paper, an efficient sensor grid deployment scheme (SGD) with a better coverage and improvised residual energy management (IREM) are proposed in the sensor based smart grid. The overall objective of the paper is to present an efficient protocol which improvises the performance of the data transmission of the nodes and conserves less energy during the transmission. A novel protocol called Dynamic Sensor Grid Coverage (DSGC) protocol is incorporated in the wireless sensor network architecture. The location of each sensor node is calculated by the weight, interference and residual energy of the particular grid. Improved Residual Energy Management (IREM) scheme is used to identify the consumption of energy by each grid in active as well as inactive states. IREM is used to find out a trade-off between the sensing power and the overall energy consumption of the grid. Residual energy and the detection probability are the metrics used for differentiating active and inactive states of the grid. By this combination, energy conserved in the sensor nodes is reduced considerably. Overlapping grid-cluster communication is also implemented to increase the efficient energy consumption. Simulation results show that Dynamic Sensor Grid Coverage protocol gives better packet delivery ratio, less packet loss and good energy conservation against the rapid mobile nature of the sensor nodes.
