최근들어 MANET(Mobile Ad-hoc Network)망과 기존 유선망을 연결한 GMAHN(Global Mobile Ad Hoc Network)에 대한 관심이 이동 통신분야에서 증가하고 있다. 시시각각 변화하는 노드의 이동성으로 인해 토폴로지가 지속적으로 변화하는 MANET 환경에서 이동 노드와 유선망간의 신뢰성 있는 데이터 전송을 위한 기술은 필수적이라고 할 수 있다. 본 논문에서는 GMAHN 환경에서 송신단과 수신단사이의 신뢰성 있는 데이터 전송을 보장하는 TCP(Transmission Control Protocol) 프로토콜(Tahoe, Reno, Vegas, SACK) 메커니즘을 이용하여 다양한 환경에 적용, 결과 값을 비교 분석하며 가장 효율적인 TCP 메커니즘을 제시하였다. Recently, GMAHN that provides interface between MANET and Wired Network has been focused in mobile communication. It is necessary that the technology provide reliable data transmission technology between mobile node and wired network in MANET environment that is varied by the node movement. In this paper, using the TCP protocol(Tahoe, Reno, Vegas, SACK)that increases reliability between source and destination, we applied the TCP protocol mechanism to various environment, and proposed the most efficient TCP mechanism by comparing each mechanism.

“Non-Installable Emergency Reporting and Rresponse System” is a disaster response system that can comply with the Golden Hour by real-time sending the location information of the report and video of the situation to the report reception desk in real-time by clicking SMS. We developed an emergency response system that can be applied to the resolution of incidents/accidents by grasping the location of the video and reporting the location of the reporter when an accident is received. The developed system utilizes the international standard HTML5 (Web RTC) technology, and can provide differentiated services.

This paper proposes a spatially distributed control scheme for a multi-layered cellular system to achieve flexible and high capacity wireless communication system under any traffic conditions including nonuniform traffic conditions. In the proposed system, terminals with lower mobility are connected to the wideband microcell systems to support variety of service including high bit rate data transmission and terminals with higher mobility are connected to the narrowband macrocell systems to reduce delay. To flexibly cope with temporal and spatial variations of traffic conditions, the ratio of the microcell and macrocell terminals as well as system bandwidth are adaptively and autonomously shared by both system Numerical simulation confirms that proposed scheme expressed flexible distributed location.
