현재 국내 및 세계 이동통신 시장에서 무선 인터넷 서비스에 대해 관심이 고조되고 있으며, WAP(Wriless Application Protcotol) 포럼, W3C(World Wide Web Consortium), 마이크로소프트사 등을 중심으로 무선인터넷에 대한 표준화가 진행되고 있다. WAP은 에릭슨, 모토롤러, 노키아, 폰닷컴등 세계 굴지의 이동통신업체들을 중심으로 약 200여 업체들이 표준화 작업에 참여하고 있으며 국제적인 산업 표준이 될 가능성이 커지고 있다. 본 연구는 Java의 특징과 RS-232C를 이용하여 운영체제에 무관하게 주차관리 보드를 이용하고 유선 인터넷을 이용하여 주차 시스템의 상황 및 통계처리를 지원하며 무선인터넷 서비스를 위해 WML과 JSP. Servlet, DBMS를 이용하여 이동통신 단말기에 주차관리 상황 및 서비스를 지원하도록 설계 및 구현하였다. 본 논문에서 제시한 컨텐츠 개발 사례를 통해 다른 응용 컨텐츠 개발방향을 제시하고 개발 과정의 문제점과 무선인터넷 서비스를 위한 JAVA와 WML의 통합 사용이 갖는 장단점을 연구하였다.

In this paper, a ubiquitous parking management system(UPMS) using sensor network is proposed. Ubiquitous parking management system provides information on free space in the parking lot through PDA or cellular phone connected to wireless LAN. For the implementation of UPMS, we have developed sensor node, sensor application and web server application. The proposed system periodically updates parking space data and monitors in real-time according to the user's request from the personal internet device. Collected parking data are stored onto the database for further analysis. The implemented UPMS system was installed on campus parking lot using 10 sensor nodes and we successfully demonstrated its feasibility by accessing the web server from out of the campus.

In this paper, we propose a parking information system which suggests an available parking lot on the shortest path between an entrance and adestination. In order to analyse the change of the parking management efficiency of each model as the number of unavailable parking lots increases from 10% to 99%, we compare the experimental results of three parking information system: an entrance-oriented system, a destination-oriented system, and the proposed system. Also, we compare user's satisfaction according to whether 50 user park their car with the proposed system or not.

s economic development has been achieved and society gets complicated, problems of traffic system have been also exposed. Due to these problems, drivers have to endure economic loss and delayed time. A web-based parking lot management system has been proposed to solve this problem. Because a parking lot is an important resource of traffic system, efficient management of parking lots can be means to solve critical problems of traffic system. In this study a simple method is introduced to detect moving vehicles with geometric information of moving objects that has been computed from surveillance cameras installed in a parking lot. Statistical information processed from image data is also stored on a server side, such as total number of parking lots, a number of parked cars and a number of available parking spots. A client who wants to know the nearest parking place can share the information via a mobile device and shorten his or her driving time. Great benefit to both drivers and society is expected if many parking lots are equipped with this system.

In this study, when another vehicle is parked in a designated space where a personal vehicle can park and a defined personal use time, an ultrasonic object recognition sensor is used to determine vehicle entry, and a camera sensor recognizes a license plate. If the vehicle is not recognized by the individual vehicle owner, the "private parking lot operation block" of the application server receives the individual phone number based on the National Police Agency's Vehicle Number Information Inquiry Open API. Afterwards, when parking is processed, the non-right holder receives the approval of the parking right holder, parks for the recognized time, and deposits the parking fee into the public account of the city hall. Through this study, it was possible to find an operation processing method that can most effectively manage parking in the city center in a private parking space recognized by the city hall.

Recently, a parking administration are more difficult because the number of cars is rapidly increasing. In particular, the number of cars, grows rapidly for years, it has arisen that a variety of violation avoids the officers' observation and that a parking place is not enough. In this paper, we design and implement a parking administration system using wireless Internet in order to efficiently control parking and administration. The implemented parking administration system consists of a server and PDA clients. The officers in charge of parking managements can receive the services promptly.

Most of campus vehicle management systems, so far, simply manages coming in or go out of vehicles, issuing a parking tickets. Recently some of them use RFID tags to count total numbers of cars in the campus, excluding exact parking position management. In this paper we propose a new campus vehicle management system using wireless sensor network location management scheme. This system adopts RSSI based location management method with some performance improvement technique. According to the experimental result, this proposed scheme can be used to implement an effective campus vehicle management system.

An efficient management system for parking lots and traffic monitoring in a metropolitan city is a very important issue, which is tightly closed to qualify of life. While a residential permit parking program has been contributing to resolve the lack of parking places, there has been no autonomous authentication system due to no apparent entrance gate and smallness of each parking zone. In this paper, we propose and implement an authentication system for residential permit parking lot using wireless sensor networks, which is cost-effective and even no need for additional managing person. Through the experimental evaluation, we analyzed relationship between the life time of sensor nodes and the various values of sleep periods to minimize power consumption of the nodes, and also showed that the difference of luminance sensed by each sensor node is at least 45 or bigger between when the parking place is occupied or not, resultingly it can be used to decide whether a parking place is occupied or not by simply detecting the change of luminance sensed.

최근 영상처리와 초음파 센서를 이용한 자동 주차 시스템을 장착한 차량들이 증가하고 있는데 기존의 자동 주차 시스템은 운전자가 탑승한 상태에서 주차 공간을 확인 후 주차를 하는 방식이다. 본 연구에서는 주차장의 주차관리 시스템과 연계하여 주차장 입구에서부터 주차 위치까지 무인자동 주차를 할 수 있도록 하는 발전된 형태의 자동 주차 시스템을 제안한다. 차량은 기존 자동 주차 시스템과 비슷하나 주차장은 일정한 구조와 표식을 이용하여 자동차의 영상처리와 센서 인식의 효율을 높여주게 되어 쉽고 안전하게 주차 할 수 있도록 도와주게 된다.
