Cognitive Transmission Based on Data Priority Classification in WSNs for Smart Grid
Smart Grid integrates digital processing, sensor technology, automatic control and communication to the traditional power grid to achieve more efficient electricity distribution and management. Applying Wireless Sensor Networks (WSNs) to Smart Grid can greatly facilitate the real-time information exchange within the power management system, and enable fast adaptation of the system to environmental changes. However, there are many challenges that need to be addressed for applying WSNs to the Smart Grid. One critical issue is how to receive data at the controller's node in a timely manner considering the typically time sensitive environment in Smart Grid and the limited battery power supply in WSNs.
