Efficient Power Utilization Techniques for Wireless Sensor Networks - A Survey

Micro-sensor networks are widely deployed sensor network in typical geographical areas where human intervention is almost impossible. A WSN is a collection of several small energy limited sensors. These devices are autonomous devices performs the job of data collection and forwarding it to the central node called sink node. The observed data can travel through multiple paths to reach sink node. Sink node performs the task of data fusion to determine a meaningful output. The micro sensors use battery power supply to achieve this goal.
