The ability to detect which wearables and smartphones are on the same body has the potential to support a wealth of applications, including user authentication, automatic data synchronization, and personalized profile loading. This paper brings this feature to commercial off-the-shelf (COTS) wearables and smartphones, by creating a virtual “on-body detection sensor” based on devices' inherent wireless...
With more and more applications of Internet of things (IoT) technologies, the quality of life of residents is one of the most important aspects in smart cities. Specially, home healthcare monitoring for the disabled and / or the elderly has become a focus of recent researches and developments. Existing home healthcare systems have drawbacks such as simple and few functionalities, weak interaction...
With booming of the technology of wireless sensor network and the technology of GSM/GPRS, this paper proposed an engineering solution of remote water quality monitor solution. The solution has been implemented and applied in monitoring the water quality of Poyang lake. Based on the mass of monitoring data, this paper proposed a model, which can be used in pridication of the quality variation of Poyang...
Many application scenarios have been revealed with Sensornets. An Error Correcting Code (ECC) will be advantageous to communications in these applications. With the different expecting on efficiency, security, usability, etc, different codes have been constructed for various purposes. The methods based on algebra theory can work well for constructing simple and usability codes. The theory of algebraic...
This paper presents a robust distributed localization approach which employs weighted least squares scaling with soft constrains. It incorporates the a priori deployment constraints, i.e., minimum and maximum node separation among 2-hop nodes, into localization as soft constraints and penalizes pairs of 2-hop nodes whose assigned coordinates violate the minimum and maximum constraints. Combined with...
An adaptive handover algorithm for wireless communication systems is addressed in this paper. Moving from the Generalized Extended Least Square handover algorithm proposed in, we model the handover mechanism as a hybrid system, and we include it in a dynamic optimization problem which is solved through the use of a trellis diagram. It's the key segment in moving Least-Square Approximation that computing...
Although medical technologies developed in the twenty-first century have successfully increased man's life span, the pressure of modern life has consequently brought many modern civilization diseases and chronic illness. When all these problems are tackled by hospitals, they will consume considerable amount of medical resources. Alternatively, providing health care services at home is an important...
This paper studies the feasibility of spatio-temporal gait analysis based upon digital textile sensors. Digitized legs and feet patterns of healthy subjects and their relations with spatio-temporal gait parameters were analyzed. In the first experiment, spatio-temporal gait parameters were determined during over ground walking. In the second experiment, predicted running, backward walking, walking...
With the adoption of sensing technology, vehicles are able to gather information about driver's environment, like speed, temperature, moisture and road condition, etc. The state-of-the-art wireless technologies also provide vehicles with the ability of communicating to their neighboring vehicles on the road, as well as the static frameworks on the road side. Vehicular Sensor Network (VSN) is an emerging...
The timing acquisition constitutes a major challenge in ultra-wideband impulse radio (UWB-IR). The challenge is not only in detecting pulses with very short duration, but also in considering RMS delay spread caused by multipath channel. This paper presents a novel data-aided synchronization acquisition algorithm. With judiciously designed algorithm and training sequence, the proposed algorithm overcomes...
