Capacity of Distributed Content Delivery in Large-Scale Wireless Ad Hoc Networks
In most existing wireless networks, end users obtain data content from the wired network, typically, the Internet. In this manner, virtually all of their traffic must go through a few access points, which implies that the capacity of wireless network is limited by the aggregated transmission data rate of these access points. To fully exploit the capability of wireless network, the authors envision that future wireless networks shall be able to provide data content within themselves. In this paper, they address the behavior of such networks from a theoretical perspective. Specifically, they consider that multicast is used for distributed content delivery, and they investigate the asymptotic upper bound of the throughput capacity for Distributed Content Delivery in large-scale Wireless Ad hoc NETworks (DCD-WANET).
