Intelligent transportation system based on SIP/ZigBee architecture
Jianhe Zhou, Chungui Li, Zengfang Zhang · 2011
In a heterogeneous network environment, constructing applications of remote distributed intelligent transportation system (ITS) are faced with complex communication problems proposed by online management, data acquisition and the coordination control of traffic node devices. Therefore, a framework based on SIP/ZigBee architecture is proposed. By using SIP and its extensions, a seamless convergence of traffic measurement and control network between the Internet and a short-range wireless sensor and actuator networks (WSAN) can be achieved. The application result shows that various remote communications and control operations of ITS distributed nodes can be unified and simplified.
