The system consists of a large amount of parking space monitoring nodes, a few parking guiding nodes, a sink node and a management station. All the nodes exchange infor- mation with each other through wireless communication. The prototype of the parking management system has been implemented and the preliminary test results show that the performance of the system can satisfy the requirements of the application. Key words Wireless sensor network, application, parking management, parking guidance 1 Introduction Wireless sensor network usually consists of a large number of low cost sensor nodes that are deployed in sensing area. These nodes can sense, sample and process information gathered from their surroundings. They form an ad hoc network to exchange information and transfer data to remote servers in a hop-by-hop manner. Wireless sensor network can be applied to many fields such as military affairs, environment monitoring, city traffic control, warehouse management, smart home, etc. This paper introduces a parking management system based on a wireless sensor network, which has several advantages over both deployment and maintenance,
