Increasing need for people to be "connected"; while at the same time remain as mobile as ever poses several interesting issues in wireless networks. It is conceivable in the near-future that wireless "hotspots" experience flash crowds-like traffic arrival pattern. A common phenomena in the Internet today characterized by sudden and unpredicted increase in(More)
Future vehicular networks are expected to deploy short-range communication technology for inter-vehicle communication. In addition to vehicle-to-vehicle communication, users will be interested in accessing the multimedia-rich Internet from within the vehicular network. This motivates a compelling application of Co-operative Networking in the Vehicular(More)
— P2P networks have emerged as a powerful multimedia content distribution mechanism. However, the widespread deployment of P2P networks are hindered by several issues, especially ones that influence end-user satisfaction, including privacy protection. In this paper, we propose GhostShare, a P2P network built on the Pastry substrate, to distribute video(More)
— AdTorrent is an integrated system for search, ranking and content delivery in car networks. AdTorrent builds on the notion of Digital Billboards, a scalable " push " model architecture for ad content delivery. We present a detailed analysis of the performance impact of key design parameters such as scope of the query flooding on the query hit ratio. Our(More)
Microsoft is producing high-quality documentation for Windows client-server and server-server protocols. Our group in the Windows organization is responsible for verifying the documentation to ensure it is of the highest quality. We are applying various test-driven methods including, when appropriate, a model-based approach. This paper describes certain(More)
Advertisements, are the most important source of revenue for some of the biggest Internet-based companies. With vehicular networks poised to become part of the Internet in the near future, this new " edge " of the Internet represents a new frontier that companies will be striving to reach. In this paper we investigate the feasibility of targeted(More)
splitting the connection. This paper takes this approach one step further by exploring the use of a TCP proxy on board a satellite for the purpose of enhancing end-to-end TCP performance. We will show this approach yields a number of important advantages, especially for small, mobile terminals, multi-segment systems, and multicast applications. As part of(More)
The problem of estimating the capacity of an Internet path is one of fundamental importance. Due to the multitude of potential applications, a large number of solutions have been proposed and evaluated. The proposed solutions so far have been successful in partially addressing the problem, but have suffered from being slow, obtrusive or inaccurate. In this(More)
This paper presents a rate adaptive medium access control (MAC) protocol for wireless networks with MIMO links. It is envisioned that the next generation high-throughput wireless LAN standard (IEEE 802.11n), which is currently under development, would use MIMO technology to achieve high data rates. An important design consideration is maintaining backward(More)
