Successful cervical cancer prevention depends on reaching, screening and treating women with pre-invasive disease. We aimed to evaluate the effectiveness of two media interventions-a photo-comic and a radio-drama-in increasing cervical screening uptake. A randomized controlled trial compared a photo-comic on cervical cancer screening with a placebo comic. One month after the comics were distrib...

Congestion is one of the major problems in today’s internet. So for managing traffic and to keep the network stable, Congestion Control algorithms are used. Queuing is one of the important method in traffic management system. This paper gives a comparative analysis of three queuing mechanisms Droptail, Random Early Detection and Non Linear Random Early Detection on the basis of various performa...

Abstract: A novel active queue management(AQM) scheme is proposed to deal with the performance degradation of TCP in wireless scenario. One of the key sources causing performance degradation is the high bit error rate(BER), which is an intrinsic link characteristic of wireless network. A high-gain observer is constructed to estimate the effect of bit error of source data. With the estimated BER...

In active queue management (AQM), core routers signal transmission control protocol (TCP) sources with the objective of managing queue utilization and delay. It is essentially a feedback control problem. Based on a recently developed dynamic model of TCPs congestion-avoidance mode, this paper does three things. First, it relates key network parameters such as the number of TCP sessions, link ca...

A new layered multicast scheme known as loss differentiated multicast congestion control architecture is proposed to provide effective congestion control in heterogeneous multicast networks. It is comprised of two components, the random early detection assisted layered multicast (RALM) and the layer marking discovery protocol (LMDP). The RALM protocol utilises the packet marking and priority dr...

In today’s world, nothing seems to be impossible, due to the astonishing advancements in science and technology. Now days, many humans are dependent on internet for their daily chores. But, congestion is one of the major issues, which affects the performance of such data networks. Thus, in order to control congestion, various schemes have been developed. In this research paper, the active queue...

Since random early detection (RED) was proposed in 1993, many active queue management (AQM) algorithms have been proposed to support better end-to-end Transmission Control Protocol (TCP) congestion control. In this article, the authors introduce and analyze a feedback control model of the TCP/AQM dynamics. Then they suggest the concept of an AQM algorithm that can detect and avoid congestion pr...
