We propose a technique in which elderly people can be monitored non-intrusively. The information is kept in an 'active' health record which becomes alive when attention or action is necessary concerning the condition of the elderly person. The proposed system consists of three main components: a sensor/actor loop, sensor records and associated active(More)
The significance of Generalized MultiProtocol Label Switching (GMPLS) has been demonstrated by its significant adoption in optical networks. In recent years GMPLS has become the most globalized solution, which operates, and is implemented in core networks. This new technology was developed to support the Internet by providing many additional services for(More)
Cloud computing has transformed a large portion of the IT industry through its ability to provision infrastructure resources – computing, networking, storage, and software as services. Software-Defined Networking (SDN) has transformed the physical underlying network infrastructure into programmable and virtualized networks. Network Functions Virtualization(More)
TCP suffers from poor throughput performance in wireless networks. Furthermore, when multiple TCP connections compete at the base station, link errors and congestion lead to serious unfairness among the connections. Although the issue of TCP performance in wireless networks has attracted significant attention, most reports focus only on TCP throughput and(More)
The paper presents the design and implementation of a distributed application called OpenBoard Tutorial System (OTS) that supports cooperative work among users of window-based workstations. The application is based on the X window system and the SUN RPC protocol. The paper describes OTS as a system designed for conducting real-time tutorial in a distributed(More)
