Power Saving and Energy Optimization Techniques for Wireless Sensor Neworks (Invited Paper)

Wireless sensor networks have become popular due to their wide range of applications. consumption is one of the biggest constraints of the sensor node and this limitation combined with a deployment of large number of nodes have added challenges to the design and management of wireless networks. They are typically used for remote monitoring in areas where providing electrical is difficult. Therefore, the devices need to be powered batteries and alternative energy sources. Because battery is limited, the use of different techniques for energy is one of the hottest topics in WSNs. In this work, we a survey of power saving and energy optimization for wireless sensor networks, which enhances the in existence and introduces the reader to the most well available methods that can be used to save energy. are analyzed from several points of view: Device , transmission, MAC and routing protocols.
