Web services for Personal Health Records (PHRs) have been deployed increasingly. However, the benefit of using PHR is still limited due to difficulty of understanding health information as well as its flexibility. Even semantic web approaches have been implemented in this domain; it is still hard to find a good practice one. To overcome this problem, we(More)
Web-based session mobility system is capability of moving HTTP session from one device to another device without interrupted and seamless web access, User may be continue using web applications at the same point on a new device without re-login or re-type any information. Web application working on HTTP is stateless protocol. A number of approaches to track(More)
Mobile IPv6 protocol allows a single Mobile Node (MN) to keep the same IPv6 address independently of its network of attachment. One of these extensions, Network Mobility (NEMO) Basic Support protocol is an extension Mobile IPv6. NEMO signaling is performed with extended Mobile IPv6 messages. NEMO Basic Support protocol is concerned with managing the(More)
In this day, the necessity of security and protection of computer information on network has become more and more important. In cryptography, asymmetric-key is the framework with high flexibility which can be applied to most of cryptographic systems using today. To reduce the encryption and decryption time which is the main drawback of asymmetric-key(More)
In this project, we have developed the computer assisting tool for persons who have hand moving problems. This software tool will help them to use a computer for those who cannot use mouse and keyboard properly. The tool detects human eyes and face actions to control mouse and keyboard as a pointer and input devices. Our project uses inexpensive equipment,(More)
SIP-based Internet Telephony is an increasingly popular communication system that is used by various users and organizations. Most of deployments are based on client/server model in traditional SIP system. Especially, conferencing function is used for voice/video conference include file transfer and share remote applications through internet network. The(More)
Enhanced route optimization for mobile IPv6 applies cryptographically generated addresses (CGAs) to improve security and reduce handover delays. However the use of CGAs requires computationally expensive algorithms. This may be an issue for small mobile devices with low processing power. It is a problem for correspondent nodes that simultaneously(More)
In this paper, we present a simple design framework of IDL (Interactive Distance Learning) based on SIP (Session Initiation Protocol). In this work, we bring some benefits to end-user over a regular video conference system which is widely used. These benefits come from features that support remote learning purpose to make teachers and students feel better(More)
To handle several online examination settings, a web-based application test management software, namely interactive examination management system (iEMS), is proposed in this paper. The outstanding points of the proposed system are its good architecture designs, ease of uses, rich features, flexibilities and extensibilities. Seven standard types of questions(More)
In this paper we discuss several issues with the present usage model for Mobile-IP that tend to limit its deployability and suggest solutions to most of these practical deficiencies. In particular, we conclude that the Mobile IP protocols and implementations should operate with any number of Home Agents. That is, from none to many.
