Abstract

In the literature, voting protocols are considered secure if they satisfy requirements such as privacy, accuracy, robustness, etc. It can be time consuming to evaluate a voting protocol with respect to all these requirements and it is not clear that the list of known requirements is complete. Perhaps because of this many papers on electronic voting do As a solution to this, we suggest evaluating voting schemes in the universal com- posability framework. We investigate the popular class of voting schemes based on homomorphic thresh ....etc

Abstract”
A major disadvantage of applying sliding mode control to dc/dc converters is that the steady-state switching frequency is affected by line and load variations. This is undesirable as it complicates the design of the input and output filters. To reduce switching frequency deviation in the events of line and load variations, an adaptive feedforward control scheme that varies the hysteresis band according to the change of line input voltage and an adaptive feedback control scheme that varies the control parameter (i.e., sliding c ....etc

Abstract”
In this letter, we analyze a class of Opportunistic Power Allocation (OPA) and sensor selection schemes for parameter estimation in wireless sensor networks. In all cases, only sensors experiencing favorable conditions participate in the estimation process by adjusting their transmit power on the basis of local Channel State Information (CSI) and Residual Energy Information. We address a number of classical problems: the minimization of distortion and transmit power, or the enhancement of network lifetime. Furthermore, we deri ....etc

Abstract

Satellite networks provides wide coverage of geographic area and high bandwidth. As satellite capacity is often limiting resource which must be used efficiently. Internet traffic is highly bursty in nature and Demand Assignment Multiple Access (DAMA) techniques are suitable provide bandwidth to match instantaneous requirements and provide significant improvements in the delay/utilization performance of Geo-stationary Earth Orbit (GEO) satellite channels supporting a finite number of users ....etc

Watermarking schemes evaluation
Abstract—Digital watermarking has been presented as a solution to copy protection of multimedia objects and dozens of schemes and algorithms have been proposed. Two main problems seriously darken the future of this technology though.
Firstly, the large number of attacks and weaknesses which appear as fast as new algorithms are proposed, emphasizes the limits of this technology and in particular the fact that it may not match users expectations.
Secondly, the requirements, to ....etc

The paper presents an original integrated MAC and routing scheme for wireless sensor networks. Our design objective is to elect the next hop for data forwarding by jointly minimizing the amount of signaling to complete a contention and maximizing the probability of electing the best candidate node. Towards this aim, we represent the suitability of a node to be the relay by means of locally calculated and generic cost metrics. Based on these costs, we analytically model the access selection problem through dynamic programming techniques, which w ....etc

Abstract
As the microprocessor speed increases from 500MHz to 1GHz and beyond, the designers must find new ways to make the cache memory for high speed access. Here, the clock to wordline path delay is optimized using a novel circuit
design technique. The delay is optimized by about 2.5 times at worst
case corner. Considering a memory element whose access time is 800ps and read and write operation occurs simultaneously in the same clock cycle, 18% improvement of the overall access time is observed. There is also a pre-decoding and p ....etc
