Users increasingly use mobile devices as their primary means to access the Internet. While it is well known that cellular network operators employ middleboxes, the details of their behavior and their impact on performance for representative Web workloads are poorly understood. This paper presents an analysis of proxy behavior and how transparent Web proxies(More)
Motivated by an availability gap for visual media, where images and videos are uploaded from mobile devices well after they are generated, we explore the selective, timely retrieval of media content from a collection of mobile devices. We envision this capability being driven by similarity-based queries posed to a cloud search front-end, which in turn(More)
In this paper we propose a framework for providing quality of information (QoI) aware networking. QoI quantifies how useful information is for an application. Its value is comprised of both intrinsic and contextual attributes related to the information. Intrinsic attributes include freshness and accuracy of the information. Contextual metrics include(More)
In this paper, we consider the design of a system in which Internet-connected mobile users contribute sensor data as training samples, and collaborate on building a model for classification tasks such as activity or context recognition. Constructing the model can naturally be performed by a service running in the cloud, but users may be more inclined to(More)
Automotive apps can improve efficiency, safety, comfort, and longevity of vehicular use. These apps achieve their goals by continuously monitoring sensors in a vehicle, and combining them with information from cloud databases in order to detect events that are used to trigger actions (e.g., alerting a driver, turning on fog lights, screening calls).(More)
Proxy Mobile IPv6 (PMIPv6), a network-based IP mobility solution, is a promising approach for mobility management in all-IP wireless networks. How to enhance its handoffrelated performance, such as handoff delay and signaling cost, is an important issue. Current solutions rely on approaches such as fast handoff, routing optimization and paging extension.(More)
In Delay Tolerant Networks, energy efficient forwarding algorithms are significant to enhance the performance of messages' transmission probability. In this paper, we focus on the problem of optimal opportunistic epidemic forwarding with energy constraint. By introducing a continuous time model, we obtain the optimal static and dynamic policies for(More)
