Study on wireless sensor networks

Constant advances in Micro Electro-Mechanical System (MEMS) technology promote miniaturization, low-cost and energy-efficiency of smart sensors. Meanwhile, Wireless Sensor Networks (WSNs) emerge as a collaborative network composed of such numerous sensors via wireless communication integrated. WSNs have a wide range of applications in the physical world, such as military surveillance, target tracking, healthcare etc. This paper illustrates a comprehensive study we contribute to in overviews, design ingredients, protocol architecture, the current research focus and the development status for WSNs with a contemporary view. © 2010 IEEE.
