A Survey of Queuing and Scheduling Mechanism of Input-queued Switches
Abstract: ABSTRACTHigh-speed routers play an important role in the Internet. A main hindrance to high-speed router design is its switch architecture. It concerns with how packets are moved from switch input ports to output ports. The switch architecture can be classified as Output-Queued and Input-Queued switches. It is well known that Output-Queued switches can achieve optimal delay-throughput performance. Output-queued switches are generally impractical for high-speed implementation because of high speed needed …

Comparative Analysis of Session Hijacking on Different Operating Systems
Abstract: ABSTRACTSession hijacking is the act of taking control of a user session after successfully obtaining or generating an authentication session id. This paper presents the comparative analysis of session hijacking on different operating systems. The experiment has been conducted on a LAN system. First, session id is captured, then hijacking is performed. The two methods for capturing the session id are used that consist of passive sniffing and active sniffing. …

Image Preprocessing Techniques
Abstract: ABSTRACTPreprocessing method is an important step, specifically for low-quality picture images. This method is robust to lighting variations and produces images with very little noise and consistent stroke width. The process computes a “surface” of background intensities at every point in the image that performs adaptive thresholding based on this result. The surface is estimated by identifying regions of low resolution text and interpolating neighboring background intensities into these regions. …

Web Services Approach to Address the Challenges in Tribal Development
Abstract: ABSTRACTIn the world of ever-maturing distributed computing, service oriented architecture (SOA) and representational state transfer (REST) are the popular distributed architectures whereas web services, Windows communication foundation (WCF), .net remoting, etc., are the core components of inter-service communications. In a multi-application environment, applications multiply very fast and consequently inter-communication complexity grows at an alarmingrate. Simplifying the inter-application communication is a long desired goal for several reasons. Specifically, in e-Governance type …
