A military tactical information communication network uses no base station and all mobile terminal are independent while mobile networks use an infra structure that a fixed base station supports many mobile terminals. A clustering system is more efficient than the existing one in small Ad-hoc network using a limited message size. The development of an adaptive clustering algorithm is necessary to maximize the network efficiency via a study on a clustering for military tactical information communication network.

The tactical data-link is useful to exchanging automatic information and controling command in combat environment. This is a essential factor of interoperability in the future combat situation of network centric warfare. In a aspect of a weapon system development, Modeling & Simulation can save expense. HLA RTI is a standard communication protocol in M&S. So, we suggest that Link Simulator connect tactical data-link through RTI. This simulator has the interoperability between M&S and tactical data-link, the reusability through adabing M&S framework, and the wide usability by automatic engagement function.

A naval tactical video has utilized to implement network based remote C2 system, but it is difficult to transmit video intelligence data between tactical combat team and base-station due to the distance and sea condition. Threrfore, We first understand the naval tactical video transmission system and identify its limitations. Finally, we present an efficient method to increase transmission rate in the naval tactical video transmission system.

Recently Korea Army developed the TICN which is the next army tactical communication system. The TICN will support ability from under environment, strategy maneuver communication system of integrated army dimension overcome and NCW. If the IER(Information Exchange Requirement) phases 3 of the future application system, the analysis that a transmission ability of the TICN is the uncapable is govern. The TICN tactical backbone's ability is very important. Therefore, network efficiency index in application and analysis of the standard protocol for the data transmission guarantee are obliged. For the TICN tactical backbone, this paper analyzes of routing protocol efficiency index and compares to superiority of the OSPF(v2) and integrated IS-IS protocols in the tactical environment. Conclusively we proposed that integrated IS-IS protocol is more suitable for TICN backbone routing protocol.

With the development of information and communication technology, the military's battle environment is changing greatly to network centric warfare in where weapon system is connected in a network and carries out mission by exchanging the real-time data. The core of the network centric warfare is Tactical Data Link(TDL) system, and subscribers of TDL exchange tactical information in real time through wireline, wireless and satellite network to share the battlefield situation. The amount of data sent and received through TDL inevitably increase as military's weapon systems equipped with TDL systems increase over time and the performance of communications equipment improves. This study proposes ways to improve the transmission speed and processing capacity of the TDL system by improving the Data Link Processor.

The Tactical Information and Communication Network system provides real-time multimedia services such as voice and data by utilizing the Mobile Subscriber Access Point. At this time, an external transmission path is constructed through the Low Capacity Trunk Radio and the High Capacity Trunk Radio system. The communication devices of each wireless transmission system are mounted on a tactical vehicle and a secondary battery is used to prevent a power interruption when the supply power to the tactical vehicle is transferred to the integrated power control device. In this paper, the basic design of the Wireless Power Transfer device for charging the battery of the integrated power control system of the mobile base station system using the Loading Distribution Method and checking the number of primary windings and the core material selection by the air gap through the Finite Elements Method.

ADAS is the air defense control system performing air surveillance and identification of ROK and near air. This system is self-developed by Air Force, currently operated successfully as the alternative system of MCRC. ADAS processes converting and combining transferred the real time radar data detected by radars. additionally, it displays significant radar data as producing in tracks. Then, it uses the message queue for IPC(Inter Process Communication). the various tactical data processed in the server is ultimately send to the network management process through the message queue for transmitting to the weapon director console. the weapon director receives this transmitted tactical data through the console to execute air defense operations. However, there is a problem that data packet is delayed or lost since the weapon Director does not receive as the amount of tactical data from the server overflowed with air tracks and missions increased. This paper improved the algorism to display and transmit the various tactical data processed from ADAS server to numbers of the weapon director console in the real time without any delay or lost. Improved the algorism, established at exercise, the development server in the real operation network and the weapon director console, is proved by comparing the number of sending tactical data packets in the server and receiving packets in the weapon director.

The Army is making efforts to increase combat power by incorporating technologies related to the Fourth Industrial Revolution into the field of defense. In order to utilize these technologies, it is necessary to develop a military tactical communication system that enables transmission and reception of data between command and control system and weapon systems. Therefore, in this paper, we analyze the tactical communication systems of the other countries, derive the limitations of the tactical communication system currently operating in the military. And, a multi-layered integrated operation structure centered on satellites and plans to provide communication on the move to small units are reviewed. Then, we present the necessity of a large-capacity transmission speed by predicting the amount of data that will be generated from weapon systems of the future, and a plan to efficiently manage the network using intelligent network technology.

Tactical networks is being operated in configuration that consisting of a variety of characteristics communication equipments and heterogeneous networks. In this configurations, end-to-end communication can be achieved using interworking gateway for converting the data format of the network and using encryption algorithm of the networks. The use of mechanism results in a problem that secure data cannot be transferred directly, reprocessing and processing delay of communication in heterogeneous tactical networks. That is, for encoding and decoding of data, the decryption of encrypted data and re-encryption processing must be required at the gateway between different networks. In this paper proposes to mechanism for end-to-end secure communication in heterogeneous tactical networks. Using the proposed method, end-to-end secure communication between heterogeneous tactical networks(PSTN-UHF networks) which removes the necessity of a gateway for converting data into data formats suitable for network to remove a transmission delay factor and enable real-time voice and data communication and achieve end-to-end security for heterogeneous tactical networks. we propose a novel mechanism for end-to-end secure communication over PSTN and UHF networks and evaluate against the performance of conventional mechanism. Our proposal is confirmed removal of security vulnerabilities, end-to-end secure communication in heterogeneous tactical networks.

Diverse sensors are equipped on P-3C Maritime Patrol Aircraft for RoKN to detect and monitor tactical targets. Tactical targets are maintained/shared by tactical computer stations which consist of a clustering network in the aircraft and displayed in various ways on TSDs(Tactical Situation Displays) for mission operators to perform their specified missions. Korea peninsula is widely covered with the sea areas and neighboured with several countries; which makes huge number of ships and aircraft deployment around the place. Due to an increase in number of sensors and enhancement of their sensitivities; we were aware of the necessity of TSD improvements to provide huge number of tactical targets and to display them efficiently. In this paper, we propose a solution for the improvements by using previous backup data and re-usage of the data, then we verify the proposal through implementation and evaluation results.
