 Bandwidth: data rate available on a network link (bit / d) (bits/second)  Available Bandwidth: unused or spare capacity of a link during a given period of time  Another way to think about it: rate at which a new flow can send data without affecting the rate of existing flows  Challenges: interference, hidden nodes (packet l) t d t ti (li k it h b t 2(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)
— Multi-hop Wireless Mesh Networks (WMNs) are becoming a popular alternative to extending the typical Wireless Local Area Networks (WLANs) we use today. Mesh networks have the advantage of low-cost incremental deployment, where wireless routers can be added at any time, in proportion to the number of users. In addition, the lack of a wired infrastructure(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 perva-siveness 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)
—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 multi-hop wireless networks. A lot of work has also been done on developing measurement-based schemes for resource management and fault management in(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)
—The increased deployment of wireless mesh networks (WMNs) should be complemented by a robust resource management scheme that can provide performance guarantees to mission-critical applications. Several admission control schemes have been presented for wireless LANs and wireless ad-hoc networks. However, wireless mesh networks, with static wireless backbone(More)
