Описание:Using dummy node concept the scalability of network can be increase. We evaluated the resiliency of our proposed system and found to have a better resiliency. To overcome this we propose a cluster based key predistribution using Steiner Triple System. For secure communication, the secret keys must be built into the nodes before deployment. Sensor nodes are tiny devices, with less computational power and memory capacity. Thus, a faster communication is achieved. Hence nodes can communicate using the built in secret keys. In this paper we use Steiner Triple system (STS) which is a combinatorial design to distribute the keys among the sensor nodes. As the keys are built into the nodes, no path key establishment phase is required for secure communication. However, STS is not an appropriate candidate for large networks, where sensors are not within the communication range of each other. Number of sensor nodes are usually much higher than the number of keys available. Distribution of keys among the sensor nodes is a challenging task.

Fedora™ Unleashed, 2008 edition

Fedora is no different, and its primary window manager is called GNOME (the Gnu Network Object Model Environment). Based on the ethos of simplicity by design, GNOME offers a rich and full interface that you can use easily to be productive. The principle design objectives include an intuitive system, meaning that it should be easy to pick up and use, as well as good localization/internationalization support and accessibility. GNOME is founded upon the X Window System, the graphical networking interface found on many Linux distributions, which provides the basis for a wide range of graphical tools and window managers. More commonly known as just X, it can also be referred to as X11R7 and X11 (such as that found on Mac OS X). Coming from the world-renowned Massachusetts Institute of Technology, X has gone through several versions, each of which has extended and enhanced the technology. The open source implementation is managed by the X.Org foundation, the board of which is made up of several key figures from the open source world ...»
