Wireless sensor networks(WSN) have unique properties that distinguished them from other wireless networks and have special challenges. Not-chargeable, not-changeable and limited power supplies of sensor nodes is the most important challenge of this networks, and if the power supply of node expired, a part of data maybe lost. Because of the importance of covers in wireless sensors, in this work ...

This paper addresses the design challenges in wireless body area networks and gives an overview of recent technological achievements to tackle these challenges. It covers the areas of wireless communication, digital signal processing, sensing and read-out, and energy harvesting. In addition, this paper presents research platforms developed at IMEC/Holst Centre to illustrates how technological b...

Wireless Sensor Networks (WSNs) have been identified for their utility in a variety of different fields such as military sensing and tracking, environmental monitoring, patient monitoring and tracking smart environments. Wireless Body Area Network (WBAN) technology is the consequence of the existing WSN technology. These networks are a composition of tiny, inexpensive and low-power biomedical n...

The increasing use of wireless networks and the constant miniaturization of electrical devices has empowered the development of Wireless Body Area Networks (WBANs). In these networks various sensors are attached on clothing or on the body or even implanted under the skin. The wireless nature of the network and the wide variety of sensors offer numerous new, practical and innovative applications...

Wireless Body Area Networks (WBANs) provide efficient communication solutions to the ubiquitous healthcare systems. Health monitoring, telemedicine, military, interactive entertainment, and portable audio/video systems are some of the applications where WBANs can be used. The miniaturized sensors together with advance micro-electro-mechanical systems (MEMS) technology create a WBAN that continu...
