In this article, we investigate energy efficient power control for the uplink of an OFDMA single-cell communication system. The user equipments decide freely their power level on the available subcarriers of the system in order to maximize their EE (Energy Efficiency) while respecting minimum normalized rate requirements. We use the non-cooperative Game theory to demonstrate that users will end by...
Brain-computer interface can have a profound impact on the life of paralyzed or elderly citizens as they offer control over various devices without any necessity of movement of the body parts. This technology has come a long way and opened new dimensions in improving our life. Use of electroencephalogram (EEG wave) based control schemes can change the shape of the lives of the disabled citizens if...
Four 5.8 GHz band transceivers at the University of Colorado at Boulder (UCB) were first operated as a wide area local area network (WLAN) in April of 2017. The purpose of this WLAN is to serve as a testbed for installations to be made in the developing world as a part of the IEEE Smart Village program. The configuration of the components is discussed in detail. The testbed is self-powered by solar...
In early 2017, Cyclone Debbie caused widespread damage and disruption to electricity supply and other infrastructure in Queensland and New South Wales. This placed considerable strain on citizens and responders alike, as they sought to find ways to keep their mobile telephones charged. Despite the advance warning of the cyclone, news reports suggest that considerable portions of the population were...
Human activity patterns such as communication and cooperation rely in large parts on smartphone-based interaction. Day-to-day available communication means are taken for granted. But in scenarios where communication infrastructure is broken, such as in the aftermath of a disaster, communication establishment becomes crucial. In those post-disaster conditions ubiquitous mobile devices carried by humans...
The recent spread of mobile networks has paved the way for building a pervasive social networking (PSN) environment, which enables people to access social networking services (SNS) anytime and from anywhere. There have been extensive studies on MANETs (Mobile Ad-hoc NETworks), which use mobile terminals for relaying information. While the feasibility of using them as emergency networks in the aftermath...
This paper presents an application that will be used in shopping malls. It is an indoor positioning system (IPS) based mobile application. The main idea is providing a win win situation between the customers and stores. It will be utilized in the store or in front of the store with a check in at the store. Thus, the customer will easily reach many offers, product explanations of the considered store...
The recent advances in wireless energy transfer technology provide a promising way to solve the problem of limited battery capacity of sensor nodes in wireless sensor networks. Adoption of mobile charger in the wireless rechargeable sensor networks (WRSNs) makes it easier to charge sensor nodes rather than charging with energy harvesting schemes. However, many existing energy replenishment schemes...
Nowadays mobile devices are multi-core computers with considerable unused capabilities. Therefore, several researchers have considered harnessing the power of these battery-powered devices for distributed computing. Although their evergrowing capabilities, the fact that mobile devices run on battery poses a major challenge for applying traditional distributed computing techniques. Particularly, researchers...
This paper presents an IoT (Internet of Things) system designed to allow the monitoring and control of parameters of the users' vehicles, anytime and anywhere in the world, through the Internet. The system prototype was developed and tested using an electric vehicle (EV) and the respective sensor systems. The main components of the proposed IoT system are: a Bluetooth Low Energy (BLE) intra-vehicular...
Mobile Cloud Computing (MCC) leverages resourceful data centers that are distant (aka the cloud) or closely located (aka edge servers) for computational offloading to overcome resource limitations of modern mobile systems like smartphones or IoT devices. Many research works investigate context-aware offloading decision algorithms aiming to find the best offloading system at runtime. However, all approaches...
This article studies nomophobia as a modern psychological attachment to smartphone as studied through Mophie advertisement “All Powerless”. Studies have shown that most youngsters suffer nomophobia to a certain degree ranging from mild to severe. In Indonesia, all studied participants are nomophobic with 71.42% suffer moderate nomophobia, 19.04% severe and 9.52% mild. Through the psychosemiotic study...
This paper considers autonomous environment discovery for energy harvesting Internet of things (IoT) applications. A self-sustainable mobile micro-robot explores an unknown environment to collect data under energy constraints. The data are fed into a machine- learning model to construct an energy harvesting map of the environment, which will then be used by IoT devices for self-sustainable operations...
Wireless sensor systems have been used in several innovative applications during past few years. However, the key constraints like system design, energy, cost are significantly application dependent. In this paper, we design a wireless sensor system towards an important environmental issue of water quality - Cyanobacterial Harmful Algal Blooms (CyanoHABs). We present a low-cost, low-energy and low-footprint...
Using smart mobile devices to support human-centric services is a frequent demand in business scenarios. As a particular challenge, tasks performed in a paper-driven way shall be digitally transformed with the use of mobile devices. With the goal to enable business applications supporting human-centric mobile services in mind, we developed a framework that extends existing process management technology...
Wireless Power Transfer (WPT) technology offers unprecedented opportunities to future cellular systems, making it possible to wirelessly recharge the mobile terminals as they get sufficiently close to the Base Stations (BSs). Here, we investigate the tradeoffs involved in the recharging process as multiple mobile users move across the cellular network, by systematically measuring the charging efficiency...
Despite the increased capabilities of mobile devices, resource-demanded mobile applications still transcend what can be accomplished on a single device. As such, mobile device cloud (MDC), an environment that enables computation-intensive tasks to be performed among a set of nearby mobile devices, offers a promising architecture to support real-time mobile applications. To stimulate mobile devices...
The increasing complexity of smartphone applications and services necessitate high battery consumption but the growth of smartphones' battery capacity is not keeping pace with these increasing power demands. To overcome this problem, researchers gave birth to the Mobile Cloud Computing (MCC) research area. In this paper we advance on previous ideas, by proposing and implementing the first known Near...
This paper considers the efficacy of using active network technology to offload computation from small mobile devices into network node computing centers. The performance of six algorithms for use in this process is compared and conclusions are drawn.
