Analysis on Energy Saving of Wireless Sensor Network

As a brand-new information acquisition and processing technology,the wireless sensor network is able to realize the independent data collection,integration and transmission,by integrating communication,sensing and calculation technologies.But the battery-powered wireless sensor network is limited in energy because of its intensive nodes.Therefore,how to reduce the energy consumption and extend the life cycle of wireless sensor network is very important.In this paper,three aspects of energy saving optimization of wireless sensor network were focused,which were single node energy consumption,routing protocol and data fusion.
