Social media is a mean to connect people through information sharing. It has been helping to use in various domains like education, business and human resource management. Healthcare domain however can be considered as one of the most potential domain to benefit from the social media participation in its different sub-domains like clinical observation, medications, professional training, patient education,...
In this work, we propose the architecture of hybrid intrusion detection system (eHIDS) for wireless sensor networks. In order to get hybrid scheme, we use combined version of anomaly and misuse detection techniques. In addition, we use cluster-based wireless sensor networks to reduce communication and computation costs. We evaluate the performance of our scheme by simulating the network and comparing...
Ubiquitous Life Care (u-Life care) nowadays becomes more attractive to computer science researchers due to a demand on a high quality and low cost of care services at anytime and anywhere. Many works exploit sensor networks to monitor patient's health status, movements, and real-time daily life activities to provide care services to them. Context information with real-time daily life activities can...
Ubiquitous Life Care (u-Life care) is one of the most focus area of research. To provide robust healthcare services, recognition of patient daily life activities is required. Context information with real-time daily life activities can help in better services, service suggestions, and change in system behaviour for better healthcare. Human health, profile, as well as activities are monitored and processed...
Sensor network ubiquitous environments may generate a lot of data including heterogeneous `raw' sensor data, low-level feature and/or trend data and higher-level context and inferenced information. This paper considers the visualization of such large, heterogeneous and complex integrated information, especially for real-time deployments facilitating rapid understanding leading to decision making....
Recent technological advances in wireless sensor networking have opened up new opportunities in healthcare systems. Future medical systems are expected to benefit the most in such areas as in-home assistance, smart nursing homes, and clinical trial. However the network system including body sensor networks and environmental sensor networks are normally comprised of energy constrained nodes. Furthermore,...
The patients benefit from the ubiquitous healthcare system by accessing healthcare services ubiquitously in unfamiliar environments. However, the patients confront the problem that they usually do not have enough knowledge about the healthcare providers in these unfamiliar environments. By collecting, distributing and aggregating feedbacks of the healthcare providers' past behaviors, reputation system...
Context-based access control is an emerging approach for modeling adaptive solution, making access control management more flexible and powerful. But in the ubiquitous environment, this approach is not enough for many emerging security vulnerabilities. Thus, improving current access control mechanisms is still necessary. Risk is an effective tool used for decision-making in economics. In this paper,...
This paper presents a novel role-based architecture for the trust model in ubiquitous environments. The role is dynamically assigned to the service requester according to the context. If the service requester requests a service that is not permitted for his role, Naive Bayes classifier is used to make decision based on the service: provider's own prior knowledge as well as the recommendations for...
