A Hierarchical Possibilistic Clustering

Abstract :-
In this paper we propose to combine two clustering approaches, namely fuzzy and possibilistic c-means. While fuzzy c-means algorithm finds suitable clusters for groups of data points, obtained memberships of data, however, encounters a major deficiency caused by misinterpretation of membership values of data points. Therefore, membership values cannot correctly interpret compatibility or degree to which data points belong to clusters. Continue reading A Hierarchical Possibilistic Clustering

Study and Analysis of Performance of IEEE 802.11 Power Saving Mode

Abstract :-
The nodes need to be turned into low-power states when they are not in use to conserve energy and power for battery- powered wireless devices. One of the most important techniques in wireless LAN and multi-hop wireless networks is the IEEE 802.11 power saving mode which is used to coordinate the power states of communication devices. Energy performance and bandwidth resource limitations are the backbone of any ad hoc network design. Continue reading Study and Analysis of Performance of IEEE 802.11 Power Saving Mode

Report on Hospital Management System

The purpose of the project entitled as “HOSPITAL MANAGEMENT SYSTEM” is to computerize the Front Office Management of Hospital to develop software which is user friendly, simple, fast, and cost – effective. It deals with the collection of patient’s information, diagnosis details, etc. Traditionally, it was done manually. Can also be used for Doctor management project.

The Routing Arbiter in the Post-NSFnet Service World

Abstract :-
In the wake of a fundamental change in the US-based Internet architecture, the Routing Arbiter (RA) is providing a stabilizing influence by maintaining coherent routing on a global scale. This is provided through the development and promotion of a globally coordinated Internet Routing Registry (IRR), the use of Route Servers (RS) at the National Science Foundation (NSF) Network Access Points (NAPs) and other exchange points, and the development and promotion of new protocols, tools, and operational practices that will facilitate the continued growth of the Internet.

A Novel Method of Fingerprint Classification Using Image Parameters on ANFIS

Abstract :-
Numerous algorithms have been developed to improve the speed of fingerprint recognition and this assumes prime importance when dealing with a large database of fingerprint images. In this paper, we propose a novel technique of using the image parameters like mean, median, variance, standard deviation and root mean square value to train an adaptive network based fuzzy inference system (ANFIS) to classify the test image into one of the six popular categories of fingerprints namely arch, tented arch, left loop, right loop, whorl and twin loop. Continue reading A Novel Method of Fingerprint Classification Using Image Parameters on ANFIS

Energy Efficiency of Encryption Schemes for Wireless Devices

Abstract :-
Encryption algorithms are known to be computationally intensive.They play a main role in information security systems. On the other side, those algorithms consume a significant amount of computing resources such as CPU time, memory, and battery power. This paper tries to present a fair comparison between the most common and used algorithms in data encryption field according to power consumption. It provides evaluation of six of the most common encryption algorithms namely: AES (Rijndael), DES, 3DES, RC2, Blowfish, and RC6. A comparison has been conducted for those encryption algorithms at different settings for each algorithm such as different sizes of data blocks, different data types, and finally encryption/decryption speed. Experimental results are given to demonstrate the effectiveness of each algorithm. Continue reading Energy Efficiency of Encryption Schemes for Wireless Devices
