Exceeding the standard for wireless sensor networks

摘要

Wireless Sensor Networks (WSNs) are becoming big business. U.S.-based analyst Harbor Research predicts the number of wireless devices and sensors shipped in 2010 will be almost 200 million, while another U.S. analyst ABI puts the number closer to 300 million. If these forecasts are accurate, there needs to be a truly pervasive networking technology that can form networks consisting of hundreds of nodes (even though at present the overwhelming majority of practical wireless networks comprise no more than ten).
