본 논문에서는 격자형 Ad-hoc 전술통신망에서 Alternating Routing Algorithm 의 적합성 연구를 수행하였다. 이 통신망의 신호 방식은 공통선 신호 방식을 사용하며, 경로선정 방식은 Flood search Routing을 사용한다. 분석 결과 alternate routing을 함으로써 좀 더 낮은 차단확률(Stocking Probability)을 기대할 수 있는 것으로 판단되었다.

위성 통신 기술의 비약적인 발전에 따라 군용 통신위성도 정보를 중계해주는 단순한 역할로부터 네트워크 중심전을 지향하는 군전술통신망의 중추적인 역할을 담당하게 될 것이다. 이에 따라 군 통신위성은 고속대용량 전송, 접속성, 생존성, 보안성 등 전술통신의 다양한 기능이 요구되며, 이러한 기능을 효율적으로 수행하기 위한 핵심요소가 디지털화된 OBP (On-Board Processing) 기술이다. 본고에서는 위성탑재 OBP의 환경 및 이에 따른 요구조건과 군위성에 탑재되는 OBP의 주요 기능인 채널화 및 역채널화, 항재밍 기술, 자원할당 기술 등에 대해 소개한다.

This paper describes the result of a case study for developing an expert system framework in order to support Korean Army tactical C4I system. Korean Army had developed an expert system, STAFS(Situation & Threat Assessment Fusion Expert System), for supporting field intelligence analysis activities which has been implemented through traditional manual process inside the division level combat briefing room. STAFS, however, has serious limitations for supporting combat commander's decision making processes because of its limited capabilities, since the system had been developed for supporting only intelligence analysis function rather than for integrated combat decision making processes inside the combat briefing room. Thus, this paper proposed an integrated expert system framework for supporting the commander's decision making by addressing various activities implemented in the briefing room.

In this paper, we propose a resource allocation scheme based on entropy for tactical wireless networks. In a tactical situation, the sensing nodes that are located randomly provide transmitted data values depending on environmental conditions. Since they share wireless resources, nodes providing valuable data compared to others need to have more resources. The proposed scheme evaluates the value of received data by a sink node. Based on the results, the sink node reallocates resources to sensing nodes. Through various experiments, we verified the proposed scheme is superior to the fixed allocation scheme.

The ROK Army is promoting cutting-edge, future-oriented military development such as a mobile, intelligent, and hyper-connected Army TIGER system. The future infantry brigade plans to increase mobility with squad-level tactical vehicles to enable combat in multi-domain operations and to deploy various weapon systems such as surveillance and reconnaissance drones. In addition, it will be developed into an intelligent unit that transmits and receives data collected through the weapon system through a hyper-connected network. Accordingly, the future infantry brigade will transmit and receive more data. However, the Army's tactical information communication system has limitations in operating as a tactical communication system for future units, such as low transmission speed and bandwidth and restrictions on communication support. Therefore, in this paper, the information distribution capability of the future infantry brigade is presented through the offensive operation scenario and M&S.

Making proper judgements in urgent situations facing a submarine at the sea is very critical. This is because the commander's misjudgments could drive the entire ally to destruction in a moment. In order to generate appropriate tactics on behalf of the human commander and to analyze the effectiveness in such emergency situations, studies using intelligent agents and genetic algorithms have been conducted. In this study, inference engine based intelligent agent is adopted to each warship and submarine to generate optimal tactics on the variable environment with genetic algorithms. And we analyze the risk of the alliance according to the performance of the enemy submarine through a simple simulation and generate appropriate tactics using the genetic algorithm. Also generated tactics are evaluated and the results are analyzed to figure out why such results are formed.

Tactical communication environment evolving for the purpose of providing services such as voice, video and text based on ALL-IP. Therefore, To be able to guarantee QoS level which meets the required level of subscriber for these services in the constrained tactical communication infrastructure, it is required to take the characteristics such as wireless transmission link, mobility of troops or personal into service quality scheme. In this paper, to support differentiated QoS for each individual or mission in the tactical communication environment, we presents a technique that can provide same QoS level which was served originally regardless of the situation to user's move through dynamically determining the QoS level to be provided at the time of the service request on VoIP-Switch.

In this paper, we designed a dynamic TDMA scheme for smooth tactical data distribution in TDMA tactical datalinks. Since the existing tactical datalinks use fixed time radio resources, it is impossible to change the resource status according to network conditions during operation. To overcome these limitations, we designed, implemented, and simulated the DTDMA processing and related messages such as initial timeslot allocation, intermediate time slot allocation, time slot return, and timeslot retrieval. As a result, it was shown that the method of effectively allocating and using timeslot resources according to the situation is applicable. Therefore, we will continue research to manage DTDMA communication on tactical data link in the future.
