Indoor location based services are increasingly important as majority of the population in highly urbanized city lives in high rise buildings. However, without a purposed-built indoor localization system like indoor Global Positioning System (GPS) or extensive survey required by fingerprinting methodology, indoor localization is not possible and useful. In this paper, we demonstrate an error minimization...
The development of communication devices, especially cellular phones has necessitated the advances of several portable and wearable technologies, such as Bluetooth headsets within wireless body area networks (WBAN). Such wearable devices use the human body as a communication channel; hence, a comprehensive understanding of the transmission mechanism between such devices is vital. This study presents...
In a smart building environment nomadic users can benefit from specialised context-sensitive services. These can increase productivity and offer an improved lifestyle for users. The data management system-context architecture (DMS-CA) has been designed to provide these services. The DMS-CA is novel in providing a completely generic system that is both user-friendly and efficient. The system is generic...
Bluetooth is very popular to be used in mobile handsets for short range data transfers. Evolution of Bluetooth headsets has added to its popularity and made it an essential part of wireless body area networks (WBAN) and wireless personal area networks (WPAN) notably the cellular phones. Human body is the integral part of such applications and affects their performance due to its lossy nature. This...
A cellular phone based online ECG processing system for ambulatory and continuous detection has been developed. It aids cardiovascular disease (CVD) patients to monitor their heart status and detect abnormalities in their normal daily life. This system is a solution to supplement the limitations in conventional clinic examination such as the difficulty in capturing rare events, off-hospital monitoring...
