Abstract
The application of wireless sensor mesh networks in Intelligent Transportation System (ITS) is presented in this paper. For a short distance transmission, the data collector collects data from Reduced Function Device (RFD) sensors node using an efficient wireless network based on Zigbee technology. A mesh sensor network is suggested instead of traditional start network. The time needed to collect a full set of data from the sensing field can be reduce largely. And reliability of communication is advanced and the delay of data transmission is shortening efficiently. For a long distance transmission, from the data collector to the traffic management, the system uses Ethernet to communicate. It is the gateway node responsible for protocol conversion from ZigBee to TCP/IP. The proposed system have abroad application foreground in the real ITS application field.
