Recent popularity of mobile devices increased the demand for mobile network services and applications that require minimal delay. 5G mobile networks are expected to provide much lesser delay than the present mobile networks. One of the conventional ways for decreasing the latency is caching the content closer to the end user. However, currently deployed methods are not effective enough. In this work-in-progress...
This paper presents an online algorithm for mobile user speed estimation in 3GPP Long Term Evolution (LTE)/LTE-Advanced (LTE-A) networks. The proposed method leverages on uplink (UL) sounding reference signal (SRS) power measurements performed at the base station, also known as eNodeB (eNB), and remains effective even under large sampling period. Extensive performance evaluation of the proposed algorithm...
In a device to device (D2D) communication underlaying cellular network, total system sum rate can be improved if cellular user equipments (UEs) and D2D pairs share resource blocks (RBs). We consider such an optimization problem where the objective is to maximize the total sum rate of the system while sharing RBs among cellular UEs and D2D pairs and maintaining some quality of service (QoS) requirements...
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...
