Making a case for the moving small cells

Abstract

On one hand, the small cells increase the overall data rate of the network. However, on the other hand, they result in increased cross-tier interference. This makes resource allocation to the cellular users more challenging. In this paper, we review a number of resource allocation schemes that are meant to reduce interference in both fixed and moving small cells. Distributed resource allocation for small cell networks aims at improving the overall system performance in terms of latency and power. A discussion that compares centralized schemes with a distributed one is also covered. We argue in this paper that distributed allocation is a better fit for the moving small cells.
