In this paper, we describes a design of Wireless Mesh Network based middleware that applied into USN(Ubiquitous Sensor Networks). WMN based middleware is a technique which links data between widely distributed sensor devices and WMN for context-awareness. The use of WMN base middleware in this paper makes possible communication on insufficiently network constructed area by use of WMN. WMN based middleware also anaylze events comprehensively that originated from specific sensor device. Based on the result from analyzed data with predetermined value WMN based middleware will given an order to designated actuator devices. Middleware operate each function of sensor network management and application service separately.

Recently research efforts for ubiquitous technology that includes RFID(Radio Frequency Deification and sensor networks are conducted very actively The architectural framework of the USN sensor network discovery service. The survey of the USN technology is conducted on four technological visions that contain USN system technology USN networking technology and USN middleware along with the service platform, With respect to each technological division domestic and worldwide leading research projects are primarily explored with their technical features and research projects are primarily explored with their technical features and research outputs. Boasted on the result of the survey we establish a USN software model that includes data sensing, sensor data storage sensor data storage sensor data naming and sensor feed name service. This main objective of this model is to provide a reference model for the facilitation of USN application developments.

In this paper, e-Meters middleware and applications using standardized middleware in the EPCglobal is suggested. An standardized middleware of the EPCglobal is designed to manage as a form of SCM and other logistics. In order to support a variety of services using RFID-based, the system must be able to support each protocol. The main features of e-Meters middleware is consist of information status and delivery, distributed database processing, event data analysis, and handling. To operate real time e-Meters system information, The realized middleware is configured to process the results of data collection.

Traditionally, Geographical Information System can only process static spatial data, which include geometries and attributes. Recently, According to Special attention is paid to ubiquitous computing environment, we require a u-GIS convergence middleware to efficiently process ubiquitous data and improves the existing GIS engine in order to enable converged processing of spatial and sensor data. So, in this study, we propose a design of u-GIS Convergence Middleware, which are based on the integration between GIS and USN technologies

In this paper, we define EMRA-based USN metadata to describe sensor device, sensor node, and sensor network information at the application level. And the proposed method for effectively storing and retrieving USN metadata based on EMRA uses agent technology. As the sensor metadata proposed in this paper is based on SensorML, interoperability can be maintained in the USN environment, and the metadata management system can be directly utilized for metadata management in USN middleware or applications.

USN 환경은 다양한 센서들을 이용하여 사용자에게 보다 다양한 서비스를 제공하는 것을 목표로 한다. 이러한 USN 환경에 존재하는 센서들은 이종이며 무수한 응용들과 요구사항을 충족하기 위한 다양한 센서 네트워크들과 응용들 사이에서 동작하는 미들웨어가 반드시 필요하다. 기존의 미들웨어에서는 이기종 센서들 간의 통합에 중점을 두고, 센서데이터를 통한 정보 획득 부분은 미흡한 상태이다. 본 연구에서는 이러한 미흡한 부분인 정보 획득 부분을 센서 데이터 패턴분석을 이용한 이상치 탐색을 통하여 중요한 여러 응용에서 유용하게 제공됨을 예를 통하여 보인다.

Modern society encounters various accidents due to industrialization and numbers of studies are going on to minimize damage from accidents. For prevention of accidents, it is necessary to design a system that helps making accurate judgment in emergency cases and is able to instantly manage each contingency. Various studies are currently going on contingency information system under ubiquitous environment. However, there have not been sufficient studies on the system that is able to monitor and process multiple contingencies and thus we still have difficulties in coping with multiple contingencies promptly. This study designs a RFID/USN middleware system for multiple contingencies control that receives data from various kinds of sensors and saves data after time marking thus is able to provide conjectured context when requested.
