Congestion in wireless sensor networks usually occurs when the traffic is heavy, so performance of the networks depends to a great extent on how well internet works. The WSNs consists of unbelievable network load and it leads to energy wastage and packet loss. This paper presents a survey of various congestion control proposals that preserve the original Node -to-Node idea of TCP by neither sen...

Several Congestion Management Mechanisms (CMMs) have been proposed for Multistage Interconnection Networks (MINs) in order to avoid the degradation of network performance when congestion appears. Most of them are based on Explicit Congestion Notification (ECN). For this purpose, switches detect congestion and, depending on the applied mechanism, some flags are marked to warn the source hosts. I...

This Informational RFC describes Data Center TCP (DCTCP): a TCP congestion control scheme for data-center traffic. DCTCP extends the Explicit Congestion Notification (ECN) processing to estimate the fraction of bytes that encounter congestion rather than simply detecting that some congestion has occurred. DCTCP then scales the TCP congestion window based on this estimate. This method achieves h...

Network congestion in wireless sensor networks (WSNs) leads to packet drops, throughput reduction and degradation of channel quality which in turn decrease network performance. A novel cross-layer congestion control strategy for WSNs is presented. The strategy performs the bandwidth and delay estimation in MAC layer for the current link, and feedbacks them to the transport layer through the cro...

It is a well known problem that errors and losses caused by unfavorable wireless link conditions cause problems for congestion controlled transport protocols such as TCP. TCP assumes that all losses occur due to network congestion. To remedy the perceived congestion, congestion avoidance is employed, typically by the TCP sender halving the sending rate. When congestion avoidance is incorrectly ...

The Internet includes various ranges of applications such as multimedia, voice and data but it endures rigorous network congestion. Further, congestion detection is an essential preventive measure must be taken to provide congestion-free Internet. To stipulate proficient technique for congestion detection, in this paper, we propose a load aware congestion detection technique in the Internet. To...

We present an improved Explicit Congestion Notification (ECN) mechanism that enables a router to signal congestion to the sender without trusting the receiver or other network devices along the signaling path. Without our mechanism, ECN-based transports can be manipulated to undermine congestion control. Web clients seeking faster downloads, for example, can trivially conceal congestion signals...
