Cloud computing is combination of various computing entities, globally separated, but electronically connected. As the geography of computation is moving towards corporate server rooms, it bring more issues including security, such as virtualization security, distributed computing, application security, identity management, access control and(More)
In recent years, wireless sensor networks (WSNs) have been considered as a potential solution for real-time monitoring applications and these WSNs have potential practical impact on next generation technology too. However, WSNs could become a threat if suitable security is not considered before the deployment and if there are any loopholes in their(More)
With the advent development in Ubiquitous Healthcare system it's becoming one of the emerging areas of research. Due to mobile, dynamic, unpredictable and heterogeneous environment of ubiquitous computing systems it's really hard to develop system software for ubiquitous computing. Primarily this middleware provide solutions to common tasks in ubiquitous(More)
Today is the world of mobile and wireless communication. With the increase of its use there are some problems still under research regarding WIMAX. One of such major problem is the security. Security is always the main issue for any network and with the wireless network it requires more concern. This work is also presented in the same area. We are(More)
In this modern era, cloud computing has evolved as a new technology for enterprise and personal computing. Many cloud services are available for customers in the market today. Each service has different terminologies, security, cost and goals. Evaluations of these cloud services are becoming more and more significant. Among the different types of cloud(More)
With advancements in hardware and software capabilities, cloud computing has evolved into a widely utilized paradigm for pay per use and robust computation. An unparalleled repository of user sensitive data that resides on the cloud poses severe threat to the privacy of individuals. Users authenticate, store and perform computations on their data using(More)
we build MUHIS (Middleware for Ubiquitous Healthcare Information System) architecture with LiveGraph, J2EE and Oracle to process different ubiquitous healthcare application's data and process that data into useful information, which can play a important role in decision making in ubiquitous Healthcare System. Application developers mostly rely on third(More)
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(More)
