Healthcare applications based on WSN are gaining high popularity all over the world due to their features like flexibility, mobility and ease of constant monitoring of the patient. The main focus of such system is remote monitoring of patient, inside and outside the hospital room and in ICU.
Obesity and overweight has been a great cause of death in 21st Century. In era of innovation in technology, people are becoming less active to complete their daily work and more use of Automation techniques are used in different scenarios. With the help of technology we try to cope up with obesity problem and make people healthier. We use WBAN and cloud computing to address this problem. It uses small...
Wireless Sensor Network is an emerging technology that is nowadays adopted in a wide range of applications. In this context, with the recent advancement in the microelectronics, communication and computation, smart and wearable wireless sensors are increasingly getting popular due to the low-cost and easy deployment. In this paper, a review of the main applications of the smart and wearable sensors...
Wireless Sensor Networks (WSN) is a significant technology that has a considerable attraction in many areas, particularly in health sector. On the other hand Wireless Mesh Networks (WMN), which are an extension of LAN, have far better range and also reduce the amount of cabling needed to connect to the backbone network. In this paper a scheme that is Wireless Sensor based Mesh Networks, which is an...
An overview of the development of a wireless sensor network (WSN) used to monitor swimmers performance is presented in this paper. The WSN is based on the functional and non-functional requirements of the user. It has been designed to monitor multiple swimmers performance simultaneously, providing feedback to the coaches and swimmers in real-time. The effect the embedded real-time processing has on...
The paper presents design and implementation of a wireless sensor node suitable for medical applications. As physiological signals are highly redundant, the data compression algorithms (Huffman's coding) are used to save energy and improve the node performance. Design is based on the ARM Cortex M1 processor and implemented in FPGA.
Wireless Sensor Networks (WSN) is neoteric progressing technology which addresses solutions to critical application environments. It allows the assimilation of medical sensors to form a group scenario which makes it feasible to remotely collect and communicate the physiological signals of a patient, thus preventing the patient from being tied to a particular set of monitoring medical instruments and...
In this investigation we have prototype a low-power, wireless, reflectance photoplethysmography (PPG) system. The PPG system consisted of a PPG sensor and a workstation. An amplifier circuit is stacked on the bottom of a commercial wireless sensor node to achieve the PPG sensor of wearable size. The PPG sensor detects the local bio-signals and radios the signals to the workstation for display and...
Remote healthcare has the potential to greatly impact many aspect of medical care. By outfitting patients with wireless, wearable vital sign sensors, collecting detailed real-time data on physiological status can be greatly simplified. Medical care has its special needs. It needs node mobility, a wide range of data rates and high degrees of reliability, and security. This paper describes our experience...
The paper reviews various recent developments in medical field and healthcare systems the network enabled sensors and emerging sensor networks that are being used to provide continuous non-obtrusive patient monitoring from nursing stations and emergency mobile units. We propose, design, and analyze a model system for developing countries based on various ICT and sensor networks projects and the work...
Wireless body area networks (WBAN) applications have emerged as one of the hottest research areas of wireless sensor networks (WSN). With the advent of miniature, cost effective and wearable sensor devices, WBAN has attracted large amount of research time. Lots of works are going on in this direction. Besides open issues in WSN like standardization, energy efficiency, security and privacy factors,...
