Abstract

The less visible contents on web are difficult to search, so web users choose other alternatives for desired information. Thus a successful website should be accessible and visible on search engines. This research aims to evaluate sample Quranic website’s web accessibility level and visibility features like: traffic rank, inlinks, and Page load time, search percentage and country visitors. The websites can play an effective role in disseminating the Message of Quran. A more visible website on search engines can be accessed by big number of users and can be beneficial for the people at large scale, which helps to increase its linkage to other websites also a sample data set of 10 Quranic websites/portals were investigated for Web Visibility and Content Accessibility. It was found that the Quranexplorer.com has attained a best traffic ranking among sample dataset. Any website following the Web Content Accessibility Guidelines can disseminate its information to many users despite users having aging or any disability problem like difficulty in hearing or vision. The research revealed several accessibility issues in terms of number of problems in sample dataset and concludes with few recommendations for good quality websites/web portals.

Abstract

DDoS is a serious issue and a ruthless attack in the networks that need to be detected and defended before reaching its target and causing the damage for user, data and the services. So, it is extremely important to prevent DDoS attack rather than letting it occur and then defending it. In this article we have used Reply Request (RREQ) with a thresh hold time mechanism to deal with this threat. We have used calculations and their analysis to detect the threat and the malicious node and with the help of reply request with thresh hold time we have proposed a detection technique and we can detect the malicious data source node as well. In this research we have evaluated the robustness of existing routing protocols against the malicious attacks and assess the quality and impact of security improvements and have proposed a reliable solution to handle DDoS attacks in MANETS.
