Abstract—
Medical image is usually comprised of region ofinterest (ROI) and region of non interest (RONI). ROI is theregion that contains the important information from diagnosispoint of view so it must be stored without any distortion. Wehave proposed a digital watermarking technique which avoidsthe distortion of image in ROI by embedding the watermarkinformation in RONI. The watermark is comprised of patientinformation, hospital logo and message authentication code,computed using hash function. Earlier BCH encryption ofwatermark is ....etc

Almost all internet applications like the streaming media and internet telephone favour reliability than time. This factor makes the TCP factor a less preferred choice. Even the UDP network cannot make up to this level as it is in short of the congestion control. These congested controlled networks are usually causes great risk factors for the use of high bandwidth UDP applications. So naturally there was need for designing a congestion-controlled unreliable transport protocol. The result, Data gram Congestion Control Protocol or DCCP gets adde ....etc

Network border patrol: preventing congestion collapse and promoting fairness in the Internet
Abstract: The Internets excellent scalability and robustness result in part from the end-to-end nature of Internet congestion control. End-to-end congestion control algorithms alone, however, are unable to prevent the congestion collapse and unfairness created by applications that are unresponsive to network congestion. To address these maladies, we propose and investigate a novel congestion-avoidance mechanism called network border patrol (NBP). NBP e ....etc

ABSTRACT
Network congestion occurs when oï¬ered traffic load exceeds available capacity at any point in a network. In wireless sensor networks, congestion causes overall channel quality to degrade and loss rates to rise, leads to buï¬er drops and increased delays (as in wired networks), and tends to be grossly unfair toward node ....etc

Datagram Congestion Control Protocol (DCCP)
Abstract
Fast-growing Internet applications like streaming media and telephony prefer timeliness to reliability, making TCP a poor fit. Unfortunately, UDP, the natural alternative, lacks con- gestion control. High-bandwidth UDP applications must im- plement congestion control themselvesa difficult taskor risk rendering congested networks unusable. We set out to ease the safe deploymentofthese applicationsbydesigninga congestion-controlledunreliable transport protocol. The out- come, the Data ....etc

Congestion Control Algorithm for Tree-based Reliable Multicast Protocols

Abstract:
This project contains a detailed description of the congestion control algorithm of tree-based reliable multicast protocol. This algorithm takes advantage of regular acknowledgements from the receivers that propagate back to the sender via the repair tree. This scalable feedback mechanism is used to collect receiver credits. Complementing the windowing mechanism, packet transmission is smoothed by using a data rate commensurate with the window size. A ....etc

Capturing Router Congestion and Delay

Abstract:
Using a unique monitoring experiment, we capture all packets crossing a (lightly utilized) operational access router from a node provider, and use them to provide a detailed examination of router congestion and packet delays. The complete capture enables not just statistics as seen from outside the router, but also an accurate physical router model to be identified. This enables a comprehensive examination of congestion and delay from three points of view: the understanding of origins, ....etc

Network Border Patrol: Preventing Congestion Collapse
ABSTRACT:-
The fundamental philosophy behind the Internet is expressed by the scalability argument: no protocol, mechanism, or service should be introduced into the Internet if it does not scale well. A key corollary to the scalability argument is the end-to-end argument: to maintain scalability, algorithmic complexity should be pushed to the edges of the network whenever possible.
Perhaps the best example of the Internet philosophy is TCP congestion control, which is implemented prima ....etc
