21세기에는 정보기술의 혁명적 발전과 함께 전쟁양상이 파격적으로 변화되어 가고 있다. 이에 따라, 분산 다중 에이전트 시스템을 위한 기술 발전이 중요시 되고 있는 상황이다. 분산 다중 에이전트 시스템을 위한 기술이 발전함에 따라 국방 분야에 연구가 활발하게 진행되어지고 있다. 그러나 지금까지 분산 다중 에이전트에 대한 연구들이 기능적인 면에서만 집중되어 왔다. 본 논문에서는 ACL(Agent Communication Language) 메시지에서 파라미터를 Emergency, Normal, System로 추가함으로써 에이전트의 실시간성을 보장하는 'QoS(Quality of Service)를 보장한 분산 다중 에이전트 플랫폼' 제안하였다. 긴급한 메시지 전송 시 QoS Manager(QOMS)를 이용하여 스케줄링 하여 에이전트 플랫폼 시스템 성능 향상을 하는 방법을 제안한다.

Until now, a study on a ubiquitous sensor network has been mainly concentrated in the areas of sensor nodes, and as a results, technologies related with sensor node were greatly developed. Despite of many achievements on research and development for a sensor node, a ubiquitous sensor network may failed to establish the actual service environment because variety of restrictions. In order to provide a actual service using a ubiquitous sensor networks applied to many results on research and development for a sensor nodes, a study on a wired/wireless composite router must be carried out. However a study on a wired/wireless composite router is relatively very slow compared with the sensor node. In this study, developed a high-performance router platform supporting IPv6 that can provide high-speed wired/wireless interface and QoS, and it can provide the multimedia service Interlocking the wireless sensor network and the Internet network. To analysis a given network environment and to develop the appropriate hardware and software in accordance with this requirement.

Recently, in the elevator of the buildings, such as apartment and office building, the visitor monitoring cameras for surveillance, advertising LCD to provide a variety of information, emergency call devices, and safe driving information sensors are installed. A variety of multimedia data from these devices to the central control office, management office, or to guard room are transmitted in real-time. Each sub-systems in the elevator are installed with a separate lines and operated independently and use different management principals, so integrated management for each sub-systems are very difficult. In this study, we develop a new IP-based multi-channel video surveillance system which is integrated surveillance camera, emergency call devices, communications devices, various sensors in the elevator, DVR, ODM, and can manage all devices by two-way communication and integrated interface. And we evaluated the performance of the developed system.
