Router buffer sizing revisited: the role of the output/input capacity ratio
The issue of router buffer sizing is still open and significant. Previous work either considers open-loop traffic or only analyzes persistent TCP flows. This paper differs in two ...

Using connection expansion to reduce control traffic in MANETs
We consider the problem of control traffic overhead in MANETs with long-lived connections, operating under a reactive routing protocol (e.g. AODV). In such settings, control traff...
