Kerberos has become a mature, reliable, secure network authentication protocol. Kerberos is based on secret key encryption technology. It is the native network authentication protocol in the Microsoft Windows 2000 operating system and may be a candidate for use as a general-purpose authentication protocol for large user communities on the Internet. Several(More)
In Wireless Sensor Networks, sensor data is sent from sensor node to base station using a relatively fixed path. This produces a certain traffic pattern, which is analyzed by an attacker to know the location of either source sensor or base station. When attacker knows the location of either source sensor or base station he can identify the location of the(More)
Federated Identity Management (FIM) is viewed as a making a guarantee to approach to encourage secure asset imparting between working together accomplices. An organized study has been done to archive the profits of embracing such frameworks from a client and business point of view. This has brought about a set of profit classifications gathering existing(More)
— Wireless sensor network is nothing but collection of wireless sensor nodes these are the battery powered devices. Wireless sensor networks (WSNs) have gained a lot of attention from both the research perspective and actual users. As sensor nodes are generally battery-powered devices, the critical problem was how to reduce the energy consumption of nodes,(More)
Now days the use of Wireless Sensor Networks (WSNs) is increasing tremendously in different real life applications. This is due to numerous advantages of WSNs such as it doesn't require centralized process, not required wired infrastructure etc. However WSNs are having constraint of energy limited resources. As compared other wireless networks, energy is(More)
The design of energy harvesting device is main part of MAC design. Recently the efficient method for energy harvesting (EH) device design for MAC protocols of WSN is studied. Practically this method proven it's efficient in terms of delivery ratio as well as energy consumption. This approach is focused on system-level considerations for networks(More)
Wireless sensor network is collection of large numbers of wireless sensor nodes to collect information from their sensing terrain. Wireless sensor nodes are battery-powered devices energy saving is always important to the lifetime of wireless sensor network. Recently many algorithms are available to track energy saving problems in wireless sensor network to(More)
Cartosat-1 data provides along track stereo data continuously with its fore and aft cameras. 10 bit quantization and near real time imaging between the stereo pairs which improve the image matching accuracies. Stereo data along with Rational Polynomial Coefficients (RPCs), provides an opportunity for photogrammetric processing for DEM and ortho image(More)
