  In recent days, digital application related smart grid system is used in electricity network. A smart grid is used to supply electricity to consumers via two-way digital communication monitoring, analysis, control and communication within the supply chain is enabled to improve efficiency, reduce energy consumption, cost and maximize the transparency and reliability of the energy supply chain. A dedicated enhancement of future power systems, greatly through renewable energy resources along with distributed communication and demand response in terms of increased efficiency and reliability is meant by smart grid system. The critical issue is that inspite of several advanced features of smart grid system, the reliability of smart grid communication system has a direct or immediate impact on the reliability of the entire power infrastructure wherein millions of smart devices are interconnected throughout critical power facilities via communication networks sleep scheduling is a technique proposal where all the nodes are not awake all the time, hence only less amount of energy is consumed during the transmission of packet at the time of execution. Sleep scheduling is a process where the nodes wake up only during packet transmission and reception time where it increases the network lifetime, else it opts sleep time.

  Formability, an important mechanical property of the sheet metal is strongly reliant on the crystallographic texture. Consequently deep drawability is also influenced. This paper deals with the perspective of crystallographic texture and its relevance with the formability of AA 5052 aluminium alloy sheet of 2 mm thickness annealed at four different temperatures namely 200 °C, 250 °C, 300 °C and 350 °C. Forming limit diagrams determined and plotted experimentally, their crystallographic textures obtained and their ODF plots prepared by X-ray diffraction were analyzed. The Forming limit diagrams (FLDs) of AA 5052 sheets annealed under different temperatures were examined with respect to the crystallographic texture point of view. The FLDs and crystallographic textures were then correlated with normal anisotropy of the sheet metal. It was found that the formability of aluminium alloy AA 5052 annealed at 350 °C possessed good formability, optimal texture and high normal anisotropy value.
