We study the fundamental problem of distributed energy-aware network formation with mobile agents of limited computational power that have the capability to wirelessly transmit and receive energy in a peer-to-peer manner. Specifically, we design simple ...

The health and security of wireless devices are fast gaining importance, and these are vital for effective implementation of sensor networks and Internet of Things (IoT). Any device, wired or wireless, needs a power source, and the power consumed is a ...

The position of an access point (AP) in a WiFi network has considerable influence on the performance of the network. In this work, we consider the problem of a WiFi AP self-positioning itself adaptively based on the network conditions to deliver ...

This paper presents an application of Deep Neural Networks to vehicular sensor data. The first goal of this work is to produce artificial readings for two sensors that have missing values: CO2 and fuel consumption. A neural network was trained to ...

In this paper, we propose QoS based radio resource allocation, where multi modal users are capable to connect to multi-RATs in heterogeneous wireless access network (HWAN). Our optimization problem is based on system sum-rate maximization under the QoS ...

As the demand for mobile data traffic increases and cellular network capacity is reaching its theoretical limit, using the unlicensed spectrum is deemed unavoidable. The deployment of the unlicensed spectrum can be a beneficiary solution to increase the ...

In this paper, we propose a new continuous verification platform on smart mobile devices. To this end, we integrate gesture-based features with interaction with social networking apps to verify user identities without minimum requirement for a password, ...

Mobile data traffic will exceed PC Internet traffic by 2020. As the number of smartphone users and the amount of data transferred per smartphone grow exponentially, limited battery power is becoming an increasingly critical problem for mobile devices ...

Low-power and Lossy network (LLN) is commonly deployed in Internet of Things applications. It consists of a considerable amount of devices, also known as motes, with sensory capacity and wireless connectivity geographically spread in a wide area. Such ...

User mobility impacts the performance of cellular networks. However, there is a lack of results on this problem because of the difficulty of the analysis. The existing results are limited to handover rate and mean path length that a user is associated ...

Vehicular Ad hoc NETworks (VANETs) will play a leading role in the next generation of wireless networks, as recent advances in vehicular networks have overcome the drawbacks of traditional wired networks. Providing safety and infotainment services to ...

Mobility has a dual role in underwater wireless sensor networks. On one hand, it might diminish the performance of networking protocols and impair network connectivity. On the other hand, it might improve data collection and boost networking-based ...

Utilizing the unlicensed spectrum for the Long Term Evolution (LTE), enables the service providers to significantly increase the capacity of the network. However, LTE has to coexist with other network technologies and especially Wi-Fi. LTE employs the ...

Wireless sensor networks play an essential role in today's Internet of Things (IoT) systems. One of the most common applications is smart indoor spaces and detecting human activities in such areas. It is crucial for these systems, to collect data, ...

Microgrids enable a network of distributed energy generators to sustain energy needs off-the-grid. Microgrids can experience islanded operational mode, being this mode a time sensitive event that affects costs of power generation and distribution. The ...

We consider a special type of Delay Tolerant Network (DTN), called "Local-Ferry-based network" (LFN), which enables communication among multiple nodes distributed over a geographic terrain. LFN utilizes controllable special purpose vehicles called "...

We assess the security mechanisms defined in the LoRaWAN specification and describe own research to show, whether those security mechanisms are sufficient. For this, we explain typical attacks on radiobased networks. We further show which precautions ...

Aggressive demand of future access network services is being translated into the stringent requirement on future backhaul infrastructure. It is not possible to take the backhaul resources for granted anymore; rather, more focused research is required to ...

Cloud Radio Access Networks (C-RAN) is an evolution in the base station architecture, mainly composed of two elements: The Base Band Unit (BBU) and the Remote Radio Head (RRH). The BBU is a centralized pool of computational resources to provide the ...
