WSN Update

U.S. researchers are testing a network of wireless sensors that can detect damage to bridges, buildings, roads and other structures instantly.

This article provides an excellent comparison of Wirless Sensor Networks versus traditional wired sensors. It describes a test conducted by researchers from Stanford University and the University of Michigan using two sensor networks to monitor a bridge. The first network contained traditional wired sensors, the second contained wirless sensor network devices. The test shows that wireless sensor devices (motes) are less expensive, more functional, and quicker and easier to install and maintain. The wireless network took an hour to install and cost roughly $1,400. The wired network took a whole day to install and cost between $10,000 and $15,000. The article shows the tremendous benefits of Wireless Sensor Networks over some of the existing technology.
