Energy-saving strategies in monitoring for Wireless Sensor Networks

The last twenty years have witnessed a great development in embedded wireless systems. Every new technology brings advantages and some disadvantages by increasing systems complexity closely related with the technological progress. The widespread use of portable devices, conclude that security and power consumption are characteristics that must be considered in terms of increased duration with improved performance and minimum cost in such systems. This becomes the motivation of a wide research range in optimizing the Wireless Sensor Networks (WSN) power consumption. In our research we investigate the possible solutions in order to reduce WSN energy consumption designed for continuous monitoring application. The question is how we manage the energy consumption of secure systems with wireless data transmission, in fact how to optimize the Energy Saving Strategy (ESS).
