Mobile ad-hoc network is a network without infrastructure where every node has its own protocols and services for powerful cooperation in the network. Every node also has the ability to handle the congestion in its queues during traffic overflow. Traditionally, this was done through Drop-Tail policy where the node drops the incoming packets to its queues during overflow condition. Many studies ...

Congestion is a wasteful stage of the production process where outputs are reduced due to excessive amount of inputs. There are several approaches in data envelopment analysis (DEA) literatures to treat congestion. The concept of strong and weak congestion first developed by Tone and Sahoo [Tone, K., Sahoo, B.K., 2004. Degree of scale economies and congestion: A unified DEA approach. European J...

Transport protocols are traditionally designed and implemented as a monolithic entity. As a result, it is extremely di cult for researchers to modify a small portion of it and evaluate it independently. This barrier encourages the re-use of existing transport protocols out of convenience even when performance is sub-optimal. In this paper, we explore the challenges of separating di erent transp...

Current TCP flow control depends on packet losses to find the workload that a network can support. Packet drops not only reduce TCP performance, but also add large transfer delay to the packets. Instead of dropping the overflowed packets, Explicit Congestion Notification (ECN) detects incipient congestion and notifies the sources to reduce their windows when the queue length exceeds a threshold...

The strong drive toward ubiquitous networks through end system mobility has made it necessary to include wireless networks, such as wireless local area networks (LANs) and satellite networks. Networks with wireless links suffer from significant packet-losses due to bit errors. The congestion detection mechanism of congestion control based on dynamic window flow control, which is widely used for...

In this paper, feature tracking based and histogram based traffic congestion detection systems are developed. Developed all system are designed to run as real time application. In this work, ORB (Oriented FAST and Rotated BRIEF) feature extraction method have been used to develop feature tracking based traffic congestion solution. ORB is a rotation invariant, fast and resistant to noise method ...

The increased diversity of Internet application requirements has spurred recent interests in exible congestion control mechanisms. Window-based congestion control schemes use increase rules to probe available bandwidth, and decrease rules to back o when congestion is detected. The parameterization of these control rules is done so as to ensure that the resulting protocol is TCP-friendly in term...

Intelligent Transportation System in case of cities is controlling traffic congestion and regulating the traffic flow. This paper presents three modules that will help in managing city traffic issues and ultimately gives advanced development in transportation system. First moduleCongestion Detection and Management will provide user real time information about congestion on the road towards his ...

Congestion is an important issue which researchers focus on in the Transmission Control Protocol (TCP) network environment. To keep the stability of the whole network, congestion control algorithms have been extensively studied. Queue management method employed by the routers is one of the important issues in the congestion control study. Active queue management (AQM) has been proposed as a rou...

Traffic congestion detection based on vehicle and tracking algorithms is one of the key technologies for intelligent transportation systems. However, in expressway surveillance scenarios, small size occlusion present severe challenges this method, including low accuracy traffic accuracy. To address these challenges, paper proposes an improved version CrowdDet algorithm by introducing Involution...
