Advances in wireless networking, micro-fabrication and integration (for example, sensors and actuators manufactured using micro-electro mechanical system technology, or MEMS), and embedded microprocessors have enabled a new generation of massive-scale sensor networks suitable for a range of commercial and military applications. The technology promises to revolutionize the way we live, work, and interact with the physical environment.

In the not-too-distant future, tiny, dirt-cheap sensors may be literally sprayed on to roads, walls, or machines, creating a digital skin that senses a variety of physical phenomena of interest; monitor pedestrian or vehicular traffic in human-aware environments and intelligent transportation grids, report wild life habitat conditions for environmental conservation, detect forest fire to aid rapid emergency response, and track job and supply chains in smart factories. Unlike current in formation services such as those on the Internet where information can easily get stale or be useless because it is too generic, sensor networks promise to couple end users directly to sensor measurements and provide information that is precisely localized in time and/or space, according to the users needs or demands.

Wireless Sensor Networks: Solutions and Market Opportunities address the important areas of the sensor networks are addressed and focusing on the present and the future areas will be presented to the reader to give a clear idea of what the sensor network is capable of. The current trends and the future prospects will be highlighted as well to make this report unique targeted towards a better understanding of sensor networks.
