Résumé :

There have been increas­ing inter­ests in employ­ing unmanned aer­i­al vehi­cles (UAVs) such as drones for telecom­mu­ni­ca­tion pur­pose. In such net­works, UAVs act as base sta­tions (BSs) and pro­vide down­load­ing ser­vice to users. Com­pared with con­ven­tion­al ter­res­tri­al base sta­tions, such UAV-BSs can dynam­i­cal­ly adjust their loca­tions to improve net­work per­for­mance. How­ev­er, there exists impor­tant issues in UAV net­works that must be con­sid­ered. For exam­ple, the UAV deploy­ment, intro­duces a new tool for radio resource man­age­ment, since BS posi­tions are open for net­work opti­miza­tion. More­over, drones have prac­ti­cal agili­ty con­straints in terms of fly­ing speed, turn­ing angles, and ener­gy con­sump­tion. The aim of this pre­sen­ta­tion is to overview the inte­gra­tion of UAVs in cel­lu­lar net­works, exist­ing issues and poten­tial solu­tions for assist­ing cel­lu­lar com­mu­ni­ca­tions with UAV-based fly­ing relays and base sta­tions. Towards that end, a pro­posed mobil­i­ty con­trol method based on the SNR mea­sure­ment and game the­o­ry approach will be pre­sent­ed. The results demon­strate that the UAV-BSs mov­ing accord­ing to our pro­posed algo­rithm sig­nif­i­cant­ly improve the net­work per­for­mance in terms of pack­et through­put and spec­tral effi­ca­cy com­pared to a base­line scenario.
