“…In addition, satellite communications can be used to support ad hoc networks in remote areas, where there were no wireless communication infrastructure in the first place. The integration between satellite and aerospace communication segments with terrestrial backbones is a key issue not only to provide continuous data connection but also assisted localization, which is essential in emergency relief [13].…”

Wireless telecommunications represent an important asset for public protection and disaster relief (PPDR) organizations as they improve the coordination and the distribution of information among first responders in the field. In large international disaster scenarios, many different PPDR organizations may participate to the response phase of disaster management. In this context, PPDR organizations may use different wireless communication technologies; such diversity may create interoperability barriers and degrade the coordination among first-time responders. In this paper, we present the design, the integration, and the testing of a demonstration system based on software-defined radio (SDR) technology and software communication architecture (SCA) to support PPDR operations with special focus on the provision of satellite communications. This paper describes the main components of the demonstration system, the integration activities as well as the testing scenarios, which were used to evaluate the technical feasibility. The paper also describes the main technical challenges in the implementation and integration of the demonstration system. Finally, future developments for this technology and potential deployment challenges are presented.

“…It is well known that the application of unmanned aerial vehicles (UAVs) has received considerable attention in both military and civilian areas, such as surveillance and reconnaissance [1], search and rescue [2] and data collection and transmission [3], since they can be quickly deployed as mobile relays to enhance network connectivity and/or extend system coverage, particularly in the scenario where the nodes are obstructed by mountains or large buildings. Under this situation, there is increasing interest in the UAV-based relay transmission technologies in wireless networks.…”

In this paper, we investigate a wireless communication system employing a multi-antenna unmanned aerial vehicle (UAV) as the relay to improve the connectivity between the base station (BS) and the receive node (RN), where the BS-UAV link undergoes the correlated Rician fading while the UAV-RN link follows the correlated Rayleigh fading with large scale path loss. By assuming that the amplify-and-forward (AF) protocol is adopted at UAV, we first propose an optimal beamforming (BF) scheme to maximize the mutual information of the UAV-assisted dual-hop relay network, by calculating the BF weight vectors and the power allocation coefficient. Then, we derive the analytical expressions for the outage probability (OP) and the ergodic capacity (EC) of the relay network to evaluate the system performance conveniently. Finally, computer simulation results are provided to demonstrate the validity and efficiency of the proposed scheme as well as the performance analysis.

“…In this context, the LBSs help the user to interact with the surrounding place and the people nearby. Moreover, the growing importance of position-based applications, such as rescue [1], [2] and commercial operations or maritime and aviation applications, pushes GNSSs such as GPS [3] to assume an important role nowadays. In order to provide global LBSs, the effectiveness of the GNSS systems is mandatory.…”

Abstract-In this work, a peer-to-peer cooperative positioning technique is presented, implemented and tested. Cooperation between two Global Positioning System (GPS) software-defined receivers is realized by resorting to an ad-hoc WLAN. The performance of aided acquisition and positioning algorithms with fine and coarse time assistance is evaluated. The fine time assistance is achieved by an ideal off-line synchronization technique, while the coarse time one is carried out by means of Network Time Protocol (NTP).
