The U.S. Department of Defense with the Joint Aerial Layer Network (JALN) concept as well as public companies like Google with their Loon project and Facebook with their solar-powered UAV concept have all invested significant funds to develop and deploy airborne high capacity backbone systems. These systems are intended to augment ground networks in support of disaster relief, to extend Internet access...
In Part I of this paper (“Delay-Optimal Dynamic Mode Selection and Resource Allocation in Device-to-Device Communications—Part I: Optimal Policy”), we investigated dynamic mode selection and subchannel allocation for an orthogonal frequency-division multiple access (OFDMA) cellular network with device-to-device (D2D) communications to minimize the average end-to-end delay performance under the dropping...
In recent years, there has been a large push in the U.S. Department of Defense (DoD) to augment ground networks with a high capacity airborne backbone network that uses directional communications technologies. Such a network could supplement the traditional SATCOM infrastructure which can become easily oversubscribed, may be degraded, or may even be unavailable. Although there are several advantages...
