Fronthaul-constrained cloud radio access networks: insights and challenges

As a promising paradigm for fifth generation wireless communication systems, cloud radio access networks (C-RANs) have been shown to reduce both capital and operating expenditures, as well as to provide high spectral efficiency (SE) and energy efficiency (EE). The fronthaul in such networks, defined as the transmission link between the baseband unit and the remote radio head, requires a high […]

Cascade with varying activation probability model for influence maximization in social networks

Activation probability is a key parameter in information diffusion models and has been observed to be varying with history activations in many empirical studies. However, such phenomenon has not been incorporated in the diffusion models applied in Influence Maximization Problem. In this paper, we first conduct empirical analyses on the large scale dataset collected from a popular online […]

Resource-constrained maximum network throughput on space networks

This paper investigates the maximum network throughput for resource-constrained space networks based on the delay and disruption-tolerant networking (DTN) architecture. Specifically, this paper proposes a methodology for calculating the maximum network throughput of multiple transmission tasks under storage and delay constraints over a space network. A mixed-integer linear programming (MILP) is formulated to solve this problem. Simulations results show […]

Wireless charger networking for mobile devices: fundamentals, standards, and applications

Wireless charging is a technique of transmitting power through an air gap to an electrical device for the purpose of energy replenishment. Recently, wireless charging technology has significantly advanced in terms of efficiency and functionality. This article first presents an overview and fundamentals of wireless charging. We then provide the review of standards, that is, […]

A Predictive Resource Allocation Algorithm in the LTE Uplink for Event Based M2M Applications

Some M2M applications such as event monitoring involve a group of devices in a vicinity that act in a co-ordinated manner. An LTE network can exploit the correlated traffic characteristics of such devices by proactively assigning resources to devices based upon the activity of neighboring devices in the same group. This can reduce latency compared […]

NDNFlow: Software-defined Named Data Networking

In this paper, we introduce NDNFlow: an open-source software implementation of a Named Data Networking based forwarding scheme in OpenFlow-controlled Software-Defined Networks (SDNs). By setting up an application-specific communication channel and controller layer parallel to the application agnostic OpenFlow protocol, we obtain a mechanism to deploy specific optimizations into a network without requiring a full […]
