Recent advancement in ubiquitous healthcare evolves to new challenges in ubiquitous communications. Secure communication in wireless sensor networks (WSNs) is one of the important issues, especially, when WSN comes to ubiquitous healthcare, where security is main requirement in sensor devices, communication and continuous real-time monitoring of patient in hospital or home network. WSN requires efficient...
A query processor to control and manage the reliability and efficiency of sensor nodes in a wireless sensor network was designed and implemented. Sensor node with the proposed query process combines environmental and medical sensors in order to monitor both pollution states of the surrounding indoor room of the patient and the patient's health status continuously. This feature allows a comprehensive...
This paper describes the designation of a real-time, wearable reflectance pulse oximetry based on a wireless sensor network. In order to monitor human physiological signals continuously, wearable reflectance pulse oximetry is built in wrist form that could used to obtain oxygen saturation of a patient unobtrusively. The wearable reflectance pulse oximetry consists of reflectance probe, SpO2 module...
Design constraints that emerged from the application's requirements have posed new challenges for design of healthcare system using wireless sensor networks. Wireless healthcare monitoring using sensor networks have some different requirements and priorities than those needed for environment, agriculture and industrial monitoring network. This paper discusses healthcare issues and describes a query...
A distributed healthcare monitoring system prototype for clinical and trauma patients, is to be developed, using wireless sensor network node. The proposed system aims to measure various vital physiological health parameters like ECG and body temperature, of patients and elderly persons and transfer his/her health status wirelessly in Ad-hoc network, to remote base station which is connected to a...
