Reliable and efficient data transfer on the Internet is an important issue. Since late 70's the protocol responsible for that has been the de facto standard TCP, which has proven to be successful through out the years, its self-managed congestion control algorithms have retained…

Active Queue Management (AQM) schemes are used for ensuring the Quality of Service (QoS) in telecommunication networks. However, they are sensitive to parameter settings and have weaknesses in detecting and controlling congestion under dynamically changing network situations. An…
Along with playing an ever-increasing role in the integration of other communication networks and expanding in application diversities, the current Internet suffers from serious overuse and congestion bottlenecks. Efficient congestion control is fundamental to ensure the Interne…
In computer networks, congestion is a condition in which one or more egressinterfaces are offered more packets than are forwarded at any given instant [1]. In wireless sensor networks, congestion can cause a number of problems including packet loss, lower throughput and poor ene…
Active Queue Management (AQM) aims to achieve high link utilization, low queuing delay and low loss rate in routers. However, it is difficult to adapt AQM parameters to constantly provide desirable transient and steady-state performance under highly dynamic network scenarios. Th…
The concept of Active Queue Management (AQM), broadly used in Internet Congestion Control, has been recently introduced to ad hoc wireless networks as a means to mitigate the severe TCP unfairness across flows. In particular, Neighborhood RED (NRED) has been proposed as an exten…
Multi-hop wireless mesh networks have emerged as an accepted communication paradigm over the last decade, although their performance is yet to reach to its full potential. Different applications of these networks, such as large-scale metropolitan wireless communication, institut…
Transmission Control Protocol (TCP) is considered one of the most important protocols in the Internet. An important mechanism in TCP is the congestion control mechanism which controls TCP sending rate and makes TCP react to congestion signals. Nowadays in heterogeneous networks,…
The cloud is part of the daily life of billions of people and is carrying most of the computation happening on the planet. To deliver the hyper computing power, the network plays a core role in connecting hundreds of thousands of machines inside datacenters. However, as many new…
