Analysis of AODV for Mobile Ad Hoc Network

An Ad hoc network is a self - configuring infrastructure less network of mobile devices connected by wireless . Routing of information differentiate these networks from other ad - hoc networks. The study of wireless sensor network is done by performing simulation done in MATLAB that can help in better understanding of behavior of various routing protocols. The motive of the mobile Ad - hoc network working group is to standardize IP routing protocol functionality suitable for wireless routing application within both static and dynamic topologies with increased dynamics due to node motion and other factors. AODV provide Quick adaptation under dynamic link conditions, Consume less network bandwidth (less broadcast) AODV is routing protocols which provide a route to destination node on demand

Kernel Learning is widely used in pattern recognition and classification problems. We look at the behaviour of Support Vector Machines which use kernels while learning a classification problem from training data. Contrary to theory, in practice, the number of support vectors needed to learn a noisy classification problem does not keep growing linearly. We have implemented a number of kernel based learning algorithms and compared their performance to study how generalization performance varies with number of support vectors.

Checkpointing and Recovery in Distributed Systems: A survey of Models, Issues and Recent Techniques A term paper submitted in partial requirement of CS553- Distributed Computing Systems

Large computing systems carry out computations for large periods of time. But the hardware they run on are not sufficiently reliable. As such it is necessary to save states of large executions on a periodic basis in order to provide reliable results from these massive executions. Checkpointing and recovery help systems save their execution states and recover from failures to provide stable results. This paper discusses the concept of Checkpointing and Recovery, issues and different implementation models with examples of a few recent implementations. The paper also suggest improvements in existing implementations.

A Survey on proxy re-encryption method using cloud computing

In many of the fields for the storage purpose we use the cloud computing. In cloud computing many technics are used for the storage and security. Cloud computing is mainly used for the security purpose to make efficient. Many of the clients can store and activate through offline mode so these papers explained about the newly technologies that used and experimented by the authors. By using the different types of technologies the quality and quantity of performances increases. By the execution of corresponding security techniques many cloud providers are safeguarded data’s, images etc. Security is the most important performance that plays a vital role in cloud computing

Two days National Conference -VISHWATECH 2014 Design of Sub Threshold Flip Flop For Ultra Low Power Applications

Abstract: Power consumption is considered as one of the important challenge in modern VLSI design along with area and speed consideration. Flip flop plays very important role in digital systems. In this paper comparative study of four different flip flops which includes pulse triggered as well as conditional technique flip flop such as IP-DCO, MHLFF, CPSFF, and CPFF topologies in sub threshold operation are examined. In recent years the ultra low power application can be possible using sub threshold technology. Using the advantage of this technology the power consumption of these flip flops is minimized. Sub threshold circuit consume less power than strong inversion circuit at the same frequency. Design is done using HSPICE in TSMC 180nm technology. The flip flops are analysed in all corners and parameters such as delay, power delay product, Energy delay product, and average power is measured at power supply voltage 300mV, and applied clock frequency is 1 MHz at temperature of 27 0
