Wireless Sensor Networks can help to mitigate the problem of congestion in cities. Congestion occurs, when the road infrastructure cannot cope with the increased demand for the particular road segment. This paper presents a congestion control system, which uses sensors installed on the road side units to monitor the data and the cars also having the capacity to collect data from the road infras...

Delay and Disruption Tolerant Networks (DTNs) are networks that experience frequent and long-lived connectivity disruptions. Unlike traditional networks, such as TCP/IP Internet, DTNs are often subject to high latency caused by very long propagation delays (e.g. interplanetary communication) and/or intermittent connectivity. Another feature that sets DTNs apart from conventional networks is tha...

Content centric networking (CCN) is a paradigm shift from the way how networks of today work. The focus of networking in CCN is on the content and not on the hosts that are involved in a communication. One of the key cornerstones of today’s communication model is the use of flow and congestion control to pipeline data and take appropriate action when perceived congestion occurs in a network. TC...

rate allocation has become a demanding task in data networks as diversity in users and traffics proliferate. most commonly used algorithm in end hosts is tcp. this is a loss based scheme therefore it exhibits oscillatory behavior which reduces network performance. moreover, since the price for all sessions is based on the aggregate throughput, losses that are caused by tcp affect other sessions...

Congestion control in Signaling System #7 faces new challenges as mobile communication systems and Intelligent Networks grow rapidly. New services change traffic patterns, add to signalling network load, and raise demands on shorter service completion times. To handle new demands, the congestion control mechanisms must foresee an overload situation, and respond to it so that the network can mai...
