Rate adaptation is a mechanism unspecified by the IEEE 802.11 standards, yet critical to the system performance by exploiting the multirate capability at the physical layer. In this paper, we conduct a systematic experimental study on rate adaptation

Network management facilitates a healthy and sustainable network. However, its practice is not well understood outside the network engineering community. In this paper, we present Robotron, a system for managing a massive production network in a top-

The poor performance of TCP in wireless networks is a well-known problem, and a large amount of research effort has been devoted to it. However, our own experiments show that existing solutions including split TCP and recently developed congestion co

Although IP multicast has been proposed and investigated for years, there are major problems inherent in the IP multicasting technique, e.g. difficulty to scale up the system, difficulty in allocating a globally unique multicast address, complexity i

Rate adaptation is a MAC-layer mechanism in IEEE 802.11 networks that ensures efficient utilization of constantly varying wireless channel. For broadcast communication, however, the current practice is to send data at base rates (i.e., 1 or 2 Mbps in

We consider a coalition network where multiple groups are interconnected via wireless links. Gateway nodes are designated by each domain to achieve a network-wide interoperability. Due to the inter-domain communication cost, the optimal gateway selec

Overlay networks have been studied extensively in recent years as a flexible means to improving the reliability, resiliency, and performance of many networking applications. In this paper we present a novel use of overlay networks and distributed mec

Interoperation in MANETs is an important issue in many operational situations, because of the growing number of heterogeneous MANETs with different standards, technologies and adminstrative management. To enable interoperation, gateways are often dep

The advancements of diverse radio technologies and emerging applications have spawned increasing heterogeneity in mobile ad hoc networks (MANETs). But the collaborative nature of communications and operations often requires that these heterogeneous M

This paper studies MIMO based rate adaptation (RA) in 802.11n wireless networks. Our case study shows that existing RA algorithms offer much lower throughput than even a fixed-rate scheme. The fundamental problem is that, all such algorithms are MIMO
