Mobile data usage over cellular networks has been dramatically increasing over the past years. Wi-Fi based wireless networks offer a high-bandwidth alternative for offloading such data traffic. However, intermittent connectivity, and battery power drain in mobile devices, inhibits always-on connectivity even in areas with good Wi-Fi coverage. This paper(More)
With over half a billion users, Online Social Networks (OSNs) are the major new applications on the Internet. Little information is available on the network impact of OSNs, although there is every expectation that the volume and diversity of traffic due to OSNs is set to explode. In this paper, we examine the specific role played by a key component of OSNs:(More)
Measurement of available bandwidth in a network has always been a topic of great interest. This knowledge can be applied to a wide variety of applications and can be instrumental in providing Quality of Service to end users. Several probe-based tools have been proposed to measure available bandwidth in wired networks. However, the performance of these tools(More)
Research in wireless mesh networks have been growing in recent years. Many testbeds have been created to study networking protocols in wireless mesh networks. In this work, we describe QuRiNet, an outdoor wide-area wireless mesh network deployed in a natural reserve. We describe various research efforts that have been leveraging the QuRiNet testbed. Several(More)
Wireless mesh networks are becoming a popular alternative to extending the wireless LANs we use today. Low-cost incremental deployment and the lack of a wired infrastructure lends mesh networks to "last-mile" solutions for ISPs or simply to aid in increased coverage area. In addition, we find that mesh networks are appropriate for our work in establishing a(More)
Proliferation of data-enabled mobile devices has fueled the popularity of smartphone applications (apps) at a rapid pace, and the trend is likely to continue for the foreseeable future. Along with the increase in popularity, the characteristics and concept of paid apps and free apps is also changing. In general, paid smartphone apps generate their revenue(More)
802.11-based multi-hop wireless mesh networks have become increasingly prevalent over the last few years. Recently, a lot of focus has been on deploying monitoring frameworks for enterprise and municipal multihop wireless networks. A lot of work has also been done on developing measurement-based schemes for resource management and fault management in these(More)
An increasing number of people today depend on the ability to connect to wireless network access points in a variety of situations. While one-hop access points were a suitable solution in the beginning, they suffered from problems such as low coverage area and over-load. One promising solution is the use of wireless mesh networks (WMNs). This allows(More)
This extended abstract describes our experiences in the deployment of QuRiNet, a wireless mesh network at the Quail Ridge Natural Reserve. Quail Ridge boasts 2,000 acres of untouched wilderness on a peninsula of Lake Berryessa, California. In deploying a mesh network at Quail Ridge, we seek to assist ecological research in the area by providing a(More)
The rapid deployment of wireless mesh networks across universities and enterprises, and the pervasiveness of mobile devices equipped with Wi-Fi connectivity, has resulted in a scenario wherein end users have the option to choose from a multitude of access points at any given location. Moreover, with the increasing availability of rich online content, there(More)
