Ad hoc self-healing of OFDMA networks using UAV-based relays

Summary Integrated frameworks have extended the applications of networks beyond a simple data sharing unit. Simultaneously, operating networks can form a layered structure that can operate as homogeneous as well as dissociated units. Networks using unmanned aerial vehicles follow similar criteria in their operability. Unmanned aerial vehicles can act as single searching unit controlled by human or can form an aerial swarm that can fly autonomously with the capability of forming an aerial network. Such aerial swarms are categorized as aerial ad hoc networks. Cooperation amongst different networks can be realized using various frameworks, models, architectures and middlewares. Several solutions have been developed that can provide easy network deployment of aerial nodes. However, a combined literature is not present that provides a comparison between these approaches. Keeping this in view, various cooperative approaches for similar formation using aerial vehicles have been discussed in this paper. The detailed study and comparative analysis of these approaches have been included. Further, the paper also includes various software solutions and their comparisons based on common parameters. Finally, various open issues have been discussed that can provide insight of ongoing research and problems that are yet to be resolved in these networks. Copyright © 2016 John Wiley & Sons, Ltd.

“…The UABSs are observed to be clustered around the cell edges in order to take over the low-SIR UEs in an effort to maximize 5th percentile rate. In the considered architecture, it is assumed that UABSs can communicate through a backhaul link to a nearby BS node [18], [19]. …”

Communications play an important role during public safety operations. Since the current communication technologies heavily rely on the backbone network, the failure of base stations (BSs) due to natural disasters or malevolent attacks causes communication difficulties for public safety and emergency communications. Recently, the use of unmanned aerial vehicles (UAVs) such as quadcopters and unmanned gliders have gained attention in public safety communications. They can be used as unmanned aerial base stations (UABSs), which can be deployed rapidly as a part of the heterogeneous network architecture. However, due to their mobile characteristics, interference management in the network becomes very challenging. In this paper, we explore the use of UABSs for public safety communications during natural disasters, where part of the communication infrastructure becomes damaged and dysfunctional (e.g., as in the aftermath of the 2011 earthquake and tsunami in Japan). Through simulations, we analyze the throughput gains that can be obtained by exploiting the mobility feature of the UAVs. Our simulation results show that when there is loss of network infrastructure, the deployment of UABSs at optimized locations can improve the throughput coverage and the 5th percentile spectral efficiency of the network. Furthermore, the improvement is observed to be more significant with higher path-loss exponents.Index Terms-5G, drone, interference coordination, LTE, public safety communications (PSC), quadcopter, unmanned aerial base stations, UAVs.

This paper addresses an important issue in ad hoc network connectivity using unmanned aerial vehicles (UAVs) as relay nodes and formulates the problem of locating UAVs in the network as a facility location problem. We propose a method to reformulate the facility location problem using quadratic unconstrained binary optimization (QUBO) and solve the QUBO model with off-shelf software. The analysis of the solutions produced by QUBO along with comparisons made with the linear model highlights both the attractiveness and robustness of the proposed approach.Haibo Wang is with Texas
