Energy harvesting has proved to be a viable solution for energy bottlenecks of wireless networks. This paper considers a single tier cellular network, in which the mobile nodes harvest energy from the aggregate downlink inter-cell interference and latter use it as uplink transmit power. A successful uplink transmission is assumed only when a user harvested enough energy in its battery and the received...
This paper analyzes two-tier heterogeneous cellular network with decoupled downlink and uplink access. The basic performance benefits of uplink/downlink decoupling have been recently introduced. Here we provide a more elaborate treatment of the decoupling mechanism by analyzing spectral and energy efficiency of the system, as the joint improvement of these two features is crucial for the upcoming...
Wireless cellular networks evolve towards a heterogeneous infrastructure, featuring multiple types of Base Stations (BSs), such as Femto BSs (FBSs) and Macro BSs (MBSs). A wireless device observes multiple points (BSs) through which it can access the infrastructure and it may choose to receive the downlink (DL) traffic from one BS and send uplink (UL) traffic through another BS. Such a situation is...
