Exponential growth in the volume of wireless data, boosted by the growing popularity of mobile devices, such as smartphone and tablets, has forced the telecommunication industries to rethink the way networks are currently designed, and to focus on the development of high-capacity mobile broadband networks. In response to this challenge, researchers have been working toward…

Energy Efficient Transmission Approach for WBAN Based on Threshold Distance
Energy efficiency is a key concern for wireless sensor nodes, especially for wireless body area network (WBAN) in which sensors operate in close vicinity to, on or even inside a human body. In this paper, we firstly present a system level energy consumption model associated with transmission distance d and transmission data rate over on-body…
Enhancing Security and Privacy for Identity-based Batch Verification Scheme in VANET
Vehicular ad hoc network (VANET) can significantly improve the traffic safety and efficiency. The basic idea is to allow vehicles to send traffic information to roadside units (RSUs) or other vehicles. Vehicles have to be prevented from some attacks on their privacy and misuse of their private data. For this reason, the security and privacy…
GFlow: Towards GPU-based high-performance table matching in OpenFlow switches
This paper investigates the acceleration of Software-based OpenFlow switches, equipped with commodity off-the-shelf hardware, for high-performance table matching. Particularly, due to the high flexibility and compatibility, software-based and SDN-compatible switches, such as OpenvSwitch, has been widely applied in several viable fields, like cloud services, future Internet architectures, and the network function virtualization (NFV). In these…
ANC-ERA: Random Access for Analog Network Coding in Wireless Networks
Analog network coding (ANC) is effective in improving spectrum efficiency. To coordinate ANC among multiple nodes without relying on complicated scheduling algorithm and network optimization, a new random access MAC protocol, called ANC-ERA, is developed to dynamically form ANC-cooperation groups in an ad hoc network. ANC-ERA includes several key mechanisms to maintain high performance in…
Data-oriented malleable reservation to revitalize spectrum fragments in elastic optical networks
This paper investigates malleable reservation (MR) for data-oriented requests to revitalize spectrum fragments in elastic optical networks. We formulate a mixed integer linear programming model and propose a time-efficient heuristic to solve the MR problem.
Asymptotic Deployment Gain: A Simple Approach to Characterize the SINR Distribution in General Cellular Networks
In cellular network models, the base stations are usually assumed to form a lattice or a Poisson point process (PPP). In reality, however, they are deployed neither fully regularly nor completely randomly. Accordingly, in this paper, we consider the very general class of motion-invariant models and analyze the behavior of the outage probability (the probability…
Bidirectional Buffer-Aided Relay Networks With Fixed Rate Transmission—Part I: Delay-Unconstrained Case
In this paper, we consider bidirectional relay networks in which two users exchange information only via a relay node, i.e., a direct link between both users is not present. We assume that channel state information at the transmitter is not available and/or only one coding and modulation scheme is used due to complexity constraints. Thus,…
Robust Restoration Decision-Making Model for Distribution Networks Based on Information Gap Decision Theory
Service restoration is important in distribution networks following an outage. During the restoration process, the system operating conditions will fluctuate, including variation of the load demand and the output from distributed generators (DGs). These variations are hard to be predicted and the load demands are roughly estimated because of absence of real-time measurements, which can…
On the Nanoscale Electromechanical Wireless Communication in the VHF Band
Electromagnetic communication at the nanoscale has, to date, been studied in either the very high frequency (VHF) (30-300 MHz) or in the TeraHertz band (0.1-10 THz). The main focus of this paper is on electromagnetic communication in the VHF band and determining the bit error rate (BER) performance of nanoscale receivers utilizing a carbon nanotube (CNT). To determine BER…
