A parking guidance and information system based on wireless sensor network

This paper introduces a parking guidance and information system based on wireless sensor system. This system consists of parking space monitoring nodes, routing nodes, sink node, parking guidance display and an information and management center. The nodes transmit the information through wireless sensor network by tree-like topological structure with non-standard protocol we developed. After analyzing and processing the data, the information and management center would distribute the parking information by LED screen and displays for the drivers. And the results of the experiment show that the performance of the system can satisfy the requirements of parking guidance.
