This paper describes a new classification system for real-time monitoring of physical activity, which is able to detect body postures (lying, sitting, and standing) and walking speed with data acquired from three wearable biaxial accelerometer sensors deployed in a wireless body sensor network. One sensor is waist-mounted while the remaining two are(More)
The increase number of mobile users in wireless environment affects query access time substantially. To minimise the query access time, one possible way is to employ data broadcasting strategy. In this paper, we propose cost models for both query access time over broadcast channel and on-demand channel. We examine the cost models to find optimum number of(More)
This article introduces MobiSense, a novel mobile health monitoring system for ambulatory patients. MobiSense resides in a mobile device, communicates with a set of body sensor devices attached to the wearer, and processes data from these sensors. MobiSense is able to detect body postures such as lying, sitting, and standing, and walking speed, by utilizing(More)
A scalable information delivery services like data broadcasting scheme is definitely of great interest especially to deal with the exponential increase of mobile users. In this paper, we present Global Indexing with data placement scheme for multi broadcast channels environment, which aims to minimize query access time, tuning time and power consumption.(More)
The emerging of wireless computing motivates radical changes of how information is derived. Our paper concerns with developing push and pull based application in wireless environment. We use a simplified e-health (hospital) context to demonstrate some effective uses of pull-based and push-based mechanisms. The pull mechanism involves information retrieval(More)
