Figure 13 Handover from cellular network to WLAN under congestion.
From a network perspective, the proposed model reduces the number of handovers between heterogeneous networks under rapid congestion scenarios, allowing the traffic to be well balanced in the ecosystem.
In this paper, a new variable partitioning strategy in Benders decomposition method is applied that enables us to deal with a wide class of mixed-integer nonlinear programming problems including fixed-charge multicommodity network design (FMND) problems under congestion effects.
It is observed that under network congestion, the CST is greater than those of random and reactive jammers.
The impact of CFP is higher in case of broadcasting, leading to longer packet delays under network congestion.
That is, the video traffic gives away a share of its network resources to the other traffic under congestion when adaptation is enabled.
We evaluate our solution with a simulation study under varying network congestion conditions.
The obstacles are removed from the map in order to evaluate the performance of protocols under increased network congestion.
The Panasonic camera in this case output "smoother" video (fewer frame drops between two successive frames) under heavy network congestion (until its on board cache is exhausted) at the cost of delays in upwards of 6 seconds.
Moreover, it cannot detect wireless losses under congestion since it has only two network states as TCP Veno.
