Minimal Impact on the Performance of Device-To-Device Communication in 5G
Abstract
Traditional cellular
network, devices are not permitted to directly communicate with each other in
the approved cellular bandwidth and all communications take place via the base
stations. In this article, we foresee a two-tier cellular network that includes
a macrocell tier (i.e., BS-to-system communications) and a system tier (i.e.,
node-to-device communications A).System terminal relaying makes it possible for
devices in a network to act as transmission relays for each other and realize a
huge ad hoc mesh network. It is clearly a radical break from the traditional
cellular architecture and presents particular technological challenges. In such
a two-tier cellular system, since the user data is routed through other users’
devices, security must be maintained for privacy. To ensure minimal impact on
the performance of existing macrocell BSs, the two-tier network needs to be
designed with smart interference management strategies and appropriate resource
allocation schemes. Furthermore, novel pricing models should be designed to
tempt devices to participate in this type of communication. Our article
provides an overview of these major challenges in two-tier networks and proposes
some pricing schemes for different types of device relaying.
