—This paper investigates the network performance loss of using only single-path routing when multiple paths are available. The performance metric is the aggregate utility achieve...
We study, from the competitive analysis perspective, the trade off between communication cost and delay cost (or simply the sendor-wait dilemma) on a hierarchy (rooted tree). The p...
Abstract. The IEEE 802.11 MAC layer is known for its unfairness behavior in ad hoc networks. Introducing fairness in the 802.11 MAC protocol may lead to a global throughput decreas...
Internet topology information is only made available in aggregate form by standard routing protocols. Connectivity information and latency characteristicsmust therefore be inferre...
We propose a novel low-cost video-on-demand architecture for heterogeneous peer-to-peer networks. The key idea of this architecture is to aggregate peers’ storage and bandwidths...
