Deployment of large population of sensors for sophisticated sensing and control in the industrial and commercial infrastructures is a challenging research area. The use of wireless sensor network (WSN) for industrial applications has attracted a great deal of interests today. Unlike the office networks, the industrial environment for wireless sensor(More)
Wireless body area network (WBAN) is an interesting application of sensor networks which can revolutionize our interaction with the outside world. WBAN like any other sensor network suffers limited energy resources and hence preserving the energy of the nodes is of great importance. Unlike typical sensor networks WBANs have few and dissimilar sensors. In(More)
This paper investigates the classification and identification of objects of different material behind a wall. The different materials are defined based on their permittivity, permeability and conductivity and include concrete, wood, glass and metal. A simulation program based on the finite difference time domain (FDTD) [1] method was first used to model(More)
—Techniques that could precisely monitor human motion are useful in applications such as rehabilitation, virtual reality, sports science, and surveillance. Most of the existing systems require wiring that restrains the natural movement. To overcome this limitation, a wearable wireless sensor network using accelerometers has been developed in this paper to(More)
Reliable on-body wireless network design needs to incorporate the natural body movements. However, existing models are static or pseudo-dynamic models. In this work, the lack of a comprehensive channel model for a moving body is addressed. A dynamic radio channel around the human body is statistically analyzed and modeled. Important parameters of the(More)
In this paper, a new method for measuring and monitoring human body joint angles, which uses wearable ultrawideband (UWB) transceivers mounted on body segments, is proposed and investigated. The model is based on providing a high ranging accuracy (intersensor distance) between a pair of transceivers placed on the adjacent segments of the joint center of(More)
A wearable wireless sensor network for human limbs monitoring. Abstract –In many applications, it is desired to monitor the human body motion to provide useful information for applications such as rehabilitation, virtual reality, sports science etc. Most existing inertial/magnetic systems used for body motion tracking today come with wiring which restrains(More)
