This paper focuses on the interaction between the Transport Control Protocol (TCP) layer and the radio interface in the High Speed Downlink Packet Access (HSDPA) wireless system. I...
We are given a directed network G = (V, A, u) with vertex set V , arc set A, a source vertex s V , a destination vertex t V , a finite capacity vector u = {uij}ijA, and a positi...
We provide first-time fixed-parameter tractability results for the NP-complete problems Maximum Full-Degree Spanning Tree and Minimum-Vertex Feedback Edge Set. These problems are...
We consider a probabilistic model for the Steiner Tree problem. Under this model the problem is defined in a 2-stage setting over a first-stage complete weighted graph having it...
—End to end available bandwidth is often constrained by IEEE 802.11 hops in the access network. Available bandwidth measurement is particularly challenging in the wireless enviro...
