A State-of-the-Art Survey on Multidimensional Scaling-Based Localization Techniques <s> B. Security <s> This paper describes the software architecture of Dragon, a real-time situational awareness virtual environment for battlefield visualization. Dragon receives data from a number of different sources and creates a single, coherent, and consistent three-dimensional display. We describe the problem of Battlefield Visualization and the challenges it imposes. We discuss the Dragon architecture, the rational for its design, and its performance in an actual application. The battlefield VR system is also suitable for similar civilian domains such as large-scale disaster relief and hostage rescue. <s> BIB001 </s> A State-of-the-Art Survey on Multidimensional Scaling-Based Localization Techniques <s> B. Security <s> In this paper, we propose a scheme in which a communication relay unmanned aerial vehicle (UAV) estimates the distribution of the terminals and selects the optimal relay position for autonomous maneuvering. In order to accomplish mission success, warfighters on the battlefield must communicate with their commander all the time. Autonomous maneuvering of a relay UAV using the proposed scheme will support their communication and mission command effectively. In the first step of the proposed scheme, the UAV estimates the distribution of the terminals using the time difference of arrival of the received signal. Once the distribution of the terminals is estimated, in the second step, the optimal relay position and altitude are determined, and the UAV maneuvers itself to relay communications. By using this scheme, there is no need to exchange specific location information, and the optimal point can be provided from the beginning of flight. In addition, this scheme has the advantage of continuous relaying at minimum power. To verify the validity and parameters of the proposed scheme, various simulations are executed and indicate the possibility of utilization in the field. <s> BIB002
The security conditions can be greatly improved around the globe by using localization. The mobility patterns and different interaction of users can be helpful to determine possible threats for security. Similarly, in war zones, a centralized MDS based localization system is helpful for the military to track its assets and troops which can increase the success of an operation BIB001 . The strategic advantage of localization is that the soldiers on the ground pay more attention to the operation and do not worry about the paths for moving forward BIB002 . In addition to that, by using centralized MDS localization method the central command can get the global view of the region and can design better plans and strategies.
