Performance enhancing proxies have drawn considerable interests from the network community a s a n eeective approach to improve user experience in cellular networks. However, previous research has been focusing on the design of proxy servers as well as the functions that these servers provide. In this paper, we study the placement of proxy servers,(More)
— Despite the extraordinary success of the cellular mobile telecommunications industry, many of the underlying design strategies and service assumptions that have served us arguably well over the past four decades may benefit from a fresh new look. Even today's LTE (Long-Term Evolution), which is designed to meet the demands of modern broadband Internet(More)
In this paper, we propose a network service that collects and processes PHY/MAC layer parameters for wireless channel conditions and provides them to adaptive mobile applications in clearly defined abstracted forms to aid them in their adaptation decision-making. This is to overcome one of the major hurdles in deploying powerful adaptive applications for(More)
As the number of wireless users and per-user bandwidth demands continue to increase, both the vendor and carrier communities agree that wireless networks must evolve toward more dense deployments. So-called " heterogeneous networks " are a commonly proposed evolution, whereby existing macro-cellular networks are supplemented with an underlay of small cells.(More)
—Wireless systems are getting deployed in many new environments with different antenna heights, frequency bands and multipath conditions. This has led to an increasing demand for more channel measurements to understand wireless propagation in specific environments and assist deployment engineering. We design and implement a rapid wireless channel sounding(More)
