The exceptional development of electronic device technology, the miniaturization of mobile devices, and the development of telecommunication technology has made it possible to monitor human biometric data anywhere and anytime by using different types of wearable or embedded sensors. In daily life, mobile devices can collect wireless body area network (WBAN) data, and the co-collected location d...

The error rate link performance has been evaluated and compared for efficient Rake receiver structures in low data rate WBAN (Wireless Body Area Network) channel. Rayleigh and Weibull distributions have been used for generating fading power profiles. This model is based on extensive measurements inside or on the surface of human body. The power profiles for WBAN channel have been generated. The...

Recent technological advances in sensors, low-power microelectronics and miniaturization, and wireless networking enabled the design and proliferation of wireless sensor networks capable of autonomously monitoring and controlling environments. One of the most promising applications of sensor networks is for human health monitoring. A number of tiny wireless sensors, strategically placed on the ...

Coexistence, and hence interference mitigation, across multiple wireless body area networks (WBANs) is an important problem as WBANs become more pervasive. Here, two-hop relay-assisted cooperative communications using opportunistic relaying (OR) is proposed for enhancement of coexistence for WBANs. Suitable time division multiple access (TDMA) schemes are employed for both intra-WBAN and inter-...

Wireless body area networks (WBAN) emerge as one of the main research streams for future wireless communications. One of the candidates for the WBAN physical layer is multiband orthogonal frequency division multiplexing ultra-wideband (MB-OFDM UWB) technology. However, despite its high data rate feature, it performs poorly in the very dispersive WBAN channel. To improve its performance, this pa...

A Wireless body area network (WBAN) is a communication network that provides both medical and consumer electronics services by using sensors in/on/around a human body. In general, a WBAN environment suffers from frequent link loss due to interferences among sensors scattered over a body. In addition, the channel condition can frequently change by postural body movement, which increases packet d...

The most common protocols for Wireless Body Area Network (WBAN) like TMAC, SMAC, ZigBee MAC, Baseline MAC protocols are analyzed in this work to evaluate the effect of various transmitted output power of nodes. When WBAN is used in patient monitoring, the analysis is required up to a great extent. In critical cases very high traffic load and accuracy of received packets is required while in nor...

Recent advances in Micro-Electro-Mechanical Systems (MEMS) technology, integrated circuits, and wireless communication have allowed the realization of Wireless Body Area Networks (WBANs). WBANs promise unobtrusive ambulatory health monitoring for a long period of time and provide real-time updates of the patient’s status to the physician. They are widely used for ubiquitous healthcare, entertai...

This paper deals with coexistence issues that may arise for Wireless Body Area Networks (WBANs) operating at the 2.45 GHz ISM band. Two different sources of interference are considered: IEEE 802.11 (Wi-Fi) and IEEE 802.15.4 (Zigbee). Firstly, these interfering networks are characterized both in the frequency and in the time domains. Then, the coexistence of a WBAN with these interfering systems...

In this paper, we integrate the IEEE 802.15.6 wireless body area networks (WBAN) with the wireless USB (WUSB) system to develop wireless communication technologies for wireless wearable computer systems. Due to portable and wearable nature of the wearable computer systems, the WUSB over IEEE 802.15.6 hierarchical medium access control (MAC) protocol has to support the power saving operation and...
