Abstract

Mobile Adhoc Network the most important and essential technologies that support future persistent computing scenario where can be exploited in a wide area of applications, from military, emergency rescue, law enforcement, commercial, to local and personal contexts. In the near future, a pervasive computing environment can be expected to be based on the recent progresses and advances in computing and communication technologies. The Next generation of mobile communications will include both prestigious infrastructure wireless networks and novel infra structure-less Mobile Adhoc Networks. With this insight, an empirical study on mobile adhoc network is being conducted. Some of the technical challenges mobile adhoc network poses are also presented. The paper points out some of the key research issues to promote the development and accelerate the commercial applications of the mobile adhoc network technology. The special characters of mobile adhoc network bring the technology with great opportunities and challenges. Therefore recently mobile adhoc network is becoming more interesting research topic and there are few research projects employed by academic and companies all over the world. Meanwhile, some of the routing protocols designed for mobile adhoc network have been proposed as Internet Draft and RFC by IETF. Observing the advantages in the integration of mobile adhoc network with significant features, we surveyed on the areas in addressing and secured routing in mobile adhoc network.

Abstract

Objectives: To find which cryptographic algorithm would produce fine result. Methods: This survey mainly focuses to an analysis of symmetric cryptographic algorithms DES, 3DES, AES, RC4 in the basis of encryption/decryption time, memory and throughput. Here .net platform has been used to simulate the results to find the best algorithm for text file transmission. Findings: Simulation tests are conducted for text files in different file sizes. These text files are given as input to each specified algorithms and calculated the results. The tests have taken seven different sizes of text files. How the above algorithms affect system resources while encryption and decryption process are explained in this project. The key focus of the project is to find the performance of the algorithms. Applications/Improvements: If the algorithm shows lowest performance in throughput/ memory/encryption time, new algorithm has to be developed to give better performance with all of these metrics.

Abstract

In India the incidence of Road Traffic accidents is reported to be 4,64,910 in 2017 among which 1,47,913 lives were dead and 4,70,975 persons were injured.Road traffic accidents result in various complications which will affect the person’s quality of life. One such complication is cognitive linguistic deficit. This case study is about a young man who has cognitive linguistic deficit which is a result of road traffic accident. The patient exhibited several complex cognitive- linguistic issues during the assessment. This includes reduced semantic memory, spared generative memory, reduced speech intelligibility, extensive surgical management and other behavioural problems. And he has speech and language difficulties such as reduced speech intelligibility, paraphasia, circumlocutions were present.
