WSN Nodes for Traffic Data-acquisition system

摘要：

With the development of intelligent transportation system (ITS), information-collection plays an increasingly important role. Research is based on Zigbee protocol for wireless sensor network technology, combined with video coding, designed a traffic data-acquisition system. Network nodes are distributed in the monitored area regularly, and responsible for collecting traffic video information, self-organizing network, sending the information to the cluster nodes to achieve dynamic display of information and large-capacity storage; for the issue of video information transmission, paper proposed a 3M algorithm which is based on the kalman filter, and then enhanced the video transmissions reliability; simulations show that data-acquisition system has high accuracy and reliability.
