Sommario/riassunto |
|
The federal government's financial condition and long-term fiscal outlook present enormous challenges to the nation's ability to respond to emerging forces reshaping American society, the United States' place in the world, and the future role of the federal government. This report includes education and employment challenges for the 21st century as one of 12 areas for reexamination, intended to help the Congress in reviewing and reconsidering the base of federal spending and tax programs. The first section sets the stage by providing the rationale for reexamining the base of the federal government and the scope of GAO's effort. The second section is organized around 12 areas of federal activity and includes narratives discussing emerging changes in each area as well as several illustrative reexamination questions for each area. The third section provides some perspective on various strategies, proc considered as a possible means to address the issues and questions raised. |

Sommario/riassunto |
|
The emerging massive density of human-held and machine-type nodes implies larger traffic deviatiolns in the future than we are facing today. In the future, the network will be characterized by a high degree of flexibility, allowing it to adapt smoothly, autonomously, and efficiently to the quickly changing traffic demands both in time and space. This flexibility cannot be achieved when the network's infrastructure remains static. To this end, the topic of UAVs (unmanned aerial vehicles) have enabled wireless communications, and networking has received increased attention. As mentioned above, the network must serve a massive density of nodes that can be either human-held (user devices) or machine-type nodes (sensors). If we wish to properly serve these nodes and optimize their data, a proper wireless connection is fundamental. This can be achieved by using UAV-enabled communication and networks. This Special Issue addresses the many existing issues that still exist to allow UAV-enabled wireless communications and networking to be properly rolled out. |
