In Wireless Sensor Networks (WSN’s), congestion plays an important role in degrading the performance of the network. Under idle condition, the network load is very low whereas when an event is detected the network load becomes high which leads to congestion. Due to congestion the overall performance of the network degrades. Hence it is necessary to detect and control congestion. In this paper a...

TCP is robust and flexible when operated on wired terrestrial networks. There are problems, however, when TCP is used on long delay satellite links. In this paper, we first study the effects that these long delays have on TCP, and then we present a transport layer solution that is implemented in OPNET 7.0. This solution enables TCP to share congestion control information among connections betwe...

This is an extension of the work done by Ghosh et al [1] whereby it was indicated that a fixed congestion window performs better than a TCP Reno implementation. This paper investigates the impact of this model on the fairness of connections and comes up with suggestion to improve this.
