Internet of vehicles for e-health applications : a potential game for optimal network capacity

Wireless technologies are pervasive to support ubiquitous healthcare applications. However, a critical issue of using wireless communications under a healthcare scenario rests at the electromagnetic interference (EMI) caused by RF transmission, and a high level of EMI may lead to a critical malfunction of medical sensors. In view of EMI on medical sensors, we propose a power control algorithm under a noncooperative game theoretic framework to schedule data transmission. Our objective is to ensure that the noncooperative game of power control can achieve a network-level objective - the optimal network capacity, although the wireless users are selfish and only interested in optimizing their own channel capacity. To obtain this objective, we show that our proposed noncooperative game is a potential game and propose the best-response-dynamics algorithm which can ensure that the game strategy of each user is induced to the optimal solution to the problem of network-level optimal capacity. Numerical results illustrate that the proposed algorithm can achieve an enhancement of 8% of network performance than the existing algorithm against the variations of mobile hospital environments. © 2007-2012 IEEE

Waveform Design for 5G and Beyond

5G is envisioned to improve major key performance indicators (KPIs), such as peak data rate, spectral efficiency, power consumption, complexity, connection density, latency, and mobility. This chapter aims to provide a complete picture of the ongoing 5G waveform discussions and overviews the major candidates. It provides a brief description of the waveform and reveals the 5G use cases and waveform design requirements. The chapter presents the main features of cyclic prefix-orthogonal frequency-division multiplexing (CP-OFDM) that is deployed in 4G LTE systems. CP-OFDM is the baseline of the 5G waveform discussions since the performance of a new waveform is usually compared with it. The chapter examines the essential characteristics of the major waveform candidates along with the related advantages and disadvantages. It summarizes and compares the key features of different waveforms.Comment: 22 pages, 21 figures, 2 tables; accepted version (The URL for the final version: https://onlinelibrary.wiley.com/doi/abs/10.1002/9781119333142.ch2

Implementation of medical imaging with telemedicine for the early detection and diagnoses of breast cancer to women in remote areas

Nowadays, the cancer topic has become a global concern. Furthermore, breast cancer persists to be the top leading cause of death to women population and the second cause of cancer death after the lung cancer globally. Various technologies and techniques have been searched, developed and studied over the years to detect the disease at the early stage; the early diagnosis saves many lives in both developed and developing countries. The detection of cancer through a screening process before its symptoms emerge increases the survival rate dramatically (Li, Meaney and Paulsen). Moreover, sufficient knowledge of the disease, qualified staff, accurate, appropriate treatment and diagnosis contribute to the successful cure of the disease; however, the cancer treatment is not affordable by many and sometimes not available to the very needy, and more precisely in developing countries. In this research, we aimed to explore the early detection of breast cancer using the new image compression algorithm: DYNAMAC, a compression tool that finds its basis in nonlinear dynamical systems theory; we implemented this algorithm through the D-transform, a digital sequence used to compress the digital media (Wang and Huang) & (Antoine, Murenzi and Vandergheynst). The goal is to use this method to analyze the average profile of diseased and healthy breast images obtained from a digital mammography to detect diseased tissues. After the detection of cancerous tumors, we worked to establish a remote care to women victims of breast cancer using the Telecommunication infrastructure through primarily Teleradiology and the Next Generation Internet (NGI) technology. Over the methods and techniques previously used in the area of medical imaging techniques, DYNAMAC algorithm is the most easily implemented along with its features that include cost saving in addition to best meeting the requirements of the breast imaging technology

When LED bulbs Becomes a Medium of Communication: Li-Fi Technology

In recent era, the use of internet is been increasing day by day. Internet has become more of a primary need than a secondary need. In recent time, Wi-Fi came into existence and life of the people by using internet got easier. But as said, every coin has two sides; Wi-Fi comes with many disadvantages like as the number of users increases for using the Wi-Fi system, the speed of the device decreases. Another disadvantage which being noticed from last few years are the ill-effects Wi-Fi causes to human health. And as every limitation has a way to new innovations. These limitation of Wi-Fi technology is being overcome by a new technology called Li-Fi (Light Fidelity) invented by Professor Harald Haas who proposes these concept as Li-Fi is a wireless optical networking technology that uses light –emitting diodes(LED’s) for data transmission. It uses same concepts that are used in infrared. DOI: 10.17762/ijritcc2321-8169.15061

Contextual Analysis of Enterprise Mobile Services Requirements

This article presents a framework to classify various types of mobile services implemented in organizational settings. Based on the objectives of wireless information systems (WIS), we identify three categories viz. enterprise mobile services, enterprise-advantage mobile services, and consumer mobile services. While the last two categories of mobile services have received broader attention, there has not been much work done in analyzing the role of mobile services in the organizational settings specific to various industries. In this article, we attempt to fill this void by synthesizing the extant literature in this area. Based on the degree of user\u27s mobility in their organizational settings, we categorize enterprise mobile services in three subcategories. This categorization helps identijy differences in the information access needs of users. We then discuss how firms belonging to various industries can benefit from mobile services and various issues that need to be addressed before embracing such services. Finally this paper concludes with identification of potential research topics

On-Site Information Systems Design for Emergency First Responders

This paper explores the design specification of on-site emergency response information systems. In particular how emerging technologies such as wireless sensor networks, RFID, and wireless communication technologies, might enable on-site dynamic information to be retrieved, shared, and presented to the first responders. The information needed for an emergency response is discussed and end-user requirements are identified through extensive interviews with fire fighters together with observation made of fire emergency response training simulations. These requirements are considered in relation to the identified responsibilities of the core members in the first responder hierarchy. On-site dynamic information collection is discussed in terms of wireless sensor networks and radio frequency identification technologies, and information sharing among the first responders is implemented based on a local wireless communication network. The on-site dynamic information required by emergency personnel is presented at three situation awareness levels in order to meet the various requirements of the first responders. Finally, a prototype information system for fire and rescue services is discussed to illustrate and evaluate the methods proposed in this paper. This work outlines the basic design principles and practice of on-site information systems for emergency first responders and shows that such an information system could greatly improve their performance as well as reducing the risks they face, once the emerging technologies are in place to implement them. Although our focus was on structural fire and fire fighters, the on-site emergency response system proposed here is applicable to other emergency response as well, due to the existence of common training methods and standard operating procedures
