Abstract:

This paper uses simulations to explore the benefits of different TCP variants. This model is an attempt at cross-comparing the different flavors of TCP under different network conditions. In this simulation we try to characterize different modes of the network by forcing different number of packets drops at an intermediate router, and under such conditions we attempt to study the performance of the TCP variants, namely Tahoe, Reno, Veno, Sack. The noteworthy aspects of the simulation would be how these variants would perform relative to each other under no congestion or low congestion conditions as well as how these performances would be increasing congestion. Simulation also takes into consideration the loss of packets due to quality of the wireless links.

Keywords: TCP Variant, Congestion Control, Modeling and Simulation etc.

Abstract:

Tiger is the National Animal Of India. It is on the border of extinction since the era of later 19th century.It is considered as on of the most Endangered Species found in the world. Its zoological name is Panthera tigris.

Project Tiger is a tiger conservation programme launched in 1973 by the Government of India during Prime Minister Indira Gandhi’s tenure. The project aims at ensuring a viable population of Bengal tigersin their natural habitats and also to protect them from extinction, and preserving areas of biological importance as a natural heritage forever represented as close as possible the diversity of ecosystems across the tiger’s distribution in the country. The project’s task force visualized these tiger reserves as breeding nuclei, from which surplus animals would migrate to adjacent forests. The Funds and commitment were mastered to support the intensive program of habitat protection and rehabilitation under the project. There are total 39 wildlife reserviours for tigers in India.

Abstract:

Wireless Sensor Network (WSN) is deployed to monitor region’s (observant field’s) parameter.  To insure the location/position of sensor node in the observant area is called Localization. Earlier many localization mechanisms had been proposed; localization with Grid Scan algorithm does not exhibit much accuracy and takes more time to localized nodes. In our paper we proposed a mechanism to cover whole region by Zig – Zag path from diagonal and from the centre of the observant field. Our proposed mechanism also covers the observant field in less time and hence energy utilization increases. The algorithm also shows better node localization and reduces Average RMS error. Further it is being observed that on varying the different value of sensor and beacons, the proposed mechanism increases performance.

Keywords – Wireless Sensor Network (WSN), Localization, Beacon, Observant field, path, Grid Scan.

Abstract:

The influence of damping co-efficient and rotatory inertia correction factor on the dynamic response to constant magnitude moving load of non-uniform Rayleigh beam is investigated in this paper. The solution technique is based on the Galerkin method, Laplace transformation and convolution theorem. The deflection profile of the non-uniform beam is calculated for several values of the damping co-efficient and rotatory inertia correcting factor and shown graphically. It is found that, as the damping co-efficient increases with fixed value of the rotatory inertia correction factor, the displacement response amplitudes of the beam model decreases. Also, increase in the values of the rotatory inertia correction factor decreases the response amplitude of the beam subjected to constant magnitude moving load. Increases in the values of the other structural parameters such as foundation modulus, shear modulus and axial force lead to decrease in the deflection profile of the beam.

Keywords: Non-uniform beam, damping co-efficient, shear modulus, foundation modulus, axial force, rotatory inertia correction factor.
