The increase in research in the area of wireless sensor networks (WSN) has brought a whole new meaning to medical devices. This is mainly due to advances in microcontroller technologies. The WSN are cited as one of the major technologies of this century and hence it assumes importance in areas such as health, psychology, fire prevention, security and even the military. The great advantage of this technology is the ability to track, monitor, study, understand and act on a particular phenomenon or event. The primary purpose of a wireless health system is reliable data transfer with minimum delay. This work is a synthesis of vast research done as Wireless Biomedical Sensor Networks (WBSN), including experimental and non-experimental investigations as well as data from the theoretical and empirical literature which incorporates a wide range of purposes: definition of concepts, review theories and evidence analysis of methodological problems, seeking to generate a consistent and understandable overview of WBSN. Such systems are already being marketed, some are still under investigation. It is also the aim of this study to identify the characteristics of a WSN applied to health. ; info:eu-repo/semantics/publishedVersion

This paper presents a comprehensive survey of security needs, applications, and current challenges and threats for 6G wireless communication networks. 6G technology has brought much attention to business entities and academia recently.

The information theoretic capacity of a single user distributed wireless communication system (DWCS) is investigated and compared to that of traditional cellular MIMO system. Simulation results show that, DWCS always outperforms traditional MIMO system, and the capacity gain increase with the incremental number of the fixed antennas. Moreover, the use of distributed antennas in DWCS can average the shadowing effect and solve the near-far problem efficiently.

Trabajo presentado al UCAmI & IWAAL 2012 - the 6th International Conference on Ubiquitous Computing and Ambient Intelligence & 4th International Workshop on Ambient Assisted Living (UCAmI & IWAAL 2012). ; This paper presents an intelligent streetlight management system based on LED lamps, designed to facilitate its deployment in existing facilities. The proposed approach, which is based on wireless communication technologies, will minimize the cost of investment of traditional wired systems, which always need civil engineering for burying of cable underground and consequently are more expensive than if the connection of the different nodes is made over the air. The deployed solution will be aware of their surrounding's environmental conditions, a fact that will be approached for the system intelligence in order to learn, and later, apply dynamic rules. The knowledge of real time illumination needs, in terms of instant use of the street in which it is installed, will also feed our system, with the objective of providing tangible solutions to reduce energy consumption according to the contextual needs, an exact calculation of energy consumption and reliable mechanisms for preventive maintenance of facilities. ; This work has been partially funded by the Basque Government under GAITEK funding program (Grants IG-2011/00264 and IG-2012/00261)

With an advancement of wireless communication technology, wireless sensor network (WSN) has emerged as one of the most powerful technologies which can be used in various applications, such as military surveillance, environment monitoring, industrial control, and medical monitoring. Wireless Sensor Network includes many devices such as smart grids, mobile phones, RFID tags, smart cards and micro-chips etc which need limited resources. In this paper, the summary of Wireless Sensor Network has been given. After that the requirement for the WSN security and various attacks on the WSN are briefly discussed. This paper depicts the various block ciphers which helps to resolve the attacks of Wireless Sensor Network and comparison of various block ciphers had also been done.

2018 Conference on Systems Engineering Research ; Technological advances in software-defined radios (SDRs), high-speed serial buses, and high-performance computing promise a significant power reduction if adopted for deployed, military wireless communications applications. This paper presents a simple mathematical power consumption model to simulate and quantify the power requirements for two communications architectures in an expeditionary command, control, communications, and computers environment. Analysis and comparison suggest that an enterprise architecture of SDRs operating under ordinary loads could result in a system-wide power reduction of 11% when compared to the currently employed architecture under the same conditions. Depending on usage profiles and equipment mix, the lower and upper bounds for system-wide power reduction by adopting an enterprise architecture were 6% and 31%, respectively. ; Naval Postgraduate School
