Advances in wireless communication, system on chip and low power sensor nodes allowed realization of Wireless Body Area Network (WBAN). WBAN comprised of tiny sensors, which collect information of patient's vital signs and provide a real time feedback. In addition, WBAN also supports many applications including Ubiquitous HealthCare (UHC), entertainment, gaming, military, etc. UHC is required b...

In this paper, we focus on an integrated system of the wireless USB over the IEEE 802.15.6 wireless body area networks (WBAN) for wireless wearable computer networks based on WiMedia MAC. However, current WBAN devices cannot share wireless channel with the existing WiMedia devices, efficiently. Existing researches are not suitable for WiMedia MAC protocol based on distributed architecture, sinc...

We recently proposed an adaptive Wireless Body Area Network (WBAN) system for mHealth service, which shows better bit error performance compared to the non-adaptive one. However, analysis and maximization of the energy efficiency as one of the key design considerations of these networks remain an open problem. Therefore, this paper investigates the energy efficiency of the proposed adaptive WBA...

Now a days, applications of Wireless Body Area Network (WBAN) have increased considerably. Mobility Management in WBAN for patient monitoring can be used which offers flexibility and mobility to patients. Use of a Mobile WBAN provides flexibility of setting up a remote monitoring system via internet or an intranet. For such a system it is very important that a WBAN can collect and transmit data...

With the increasing demand of wireless body area network (WBAN) for patient monitoring systems, it is necessary to develop efficient energy management systems to either prolong node battery replacement time or to develop batteryless WBAN nodes. In this paper, we introduce an energy harvesting WBAN architecture that combines the energy harvesting system and an adaptable duty cycle adjustment alg...

Wireless body area networks (WBANs) in the industrial, scientific, and medical (ISM) bands have been increasingly adopted for various medical applications. Due to the shared nature of the ISM bands, when a WBAN coexists with a wireless local area network (WLAN), performance of WBAN may significantly degrade because of asymmetric attributes between WBAN and WLAN such as transmit power and respon...

Resumé Dans le cadre de cette thèse, on se proposait de développer de nouveaux mécan-ismes de radiolocalisation, permettant de positionner les noeuds de réseaux cor-porels sans-l (WBAN) mobiles, en exploitant de manière opportuniste des liens radio coopératifs bas débit à l'échelle d'un même corps (i.e. coopération intra-WBAN), entre rèseaux distincts (i.e. coopération inter-WBAN), et/ou vis-à-...

Wireless Body Area Networks (WBANs) applications have emerged as one of the most recent research areas of wireless sensor networks. Lots of research is improving QoS factors in sensor networks. However, QoS requirements vary from application to application, WBAN applications are very sensitive, and QoS issues in WBAN need major concern and focus. This paper outlines the WBANs QoS requirements a...

In this paper, we propose a short ranging middleware built on WUSB (Wireless USB) over WBAN (Wireless Body Area Networks) hierarchical protocol for body sensor networks. The proposed middleware platform is composed of time-synchronization and optimal short ranging solution. The optimal ranging solution is proposed through comparison of experiment results from ToA (Time of Arrival), TDoA (Time D...

In order to improve the control overhead and to achieve the reliable data transmission in the patient monitoring system based on ZigBee, here the concentration is given on the comparative performance evaluation of different routing algorithm in a wireless body area network (WBAN) using the OPNET simulation tools. WBAN contains the number of wireless mobile nodes forming an unpredictable topolog...
