In this paper we apply the Named Data Networking [1], a newly proposed Internet architecture, to networking vehicles on the run. Our initial design, dubbed V-NDN, illustrates NDN's promising potential in providing a unifying architecture that enables networking among all computing devices independent from whether they are connected through wired infrastructure, ad hoc, or intermittent DTN. This paper...
The last hop of the Internet towards the end-user is mostly supported by wireless technologies and thus interconnects multiple users, that should, ideally, be served simultaneously. The shared media capability of such last hop is, however, underused, asthe principle behind wireless technologies implies that only one user can be served at an instant in time. Aiming at allowing multiuser transmission...
The careful deployment of hotspots in metropolitan areas allow to maximize WiFi offloading, a viable solution to the recent boost up of mobile data consumption. Our proposed strategy considers routine characteristics present on people's daily trajectories, the space-time interaction between them urban locations, and their transportation modes. Using a reallife metropolitan trace, we show our routine-based...
We tackle the network selection problem in operator-initiated mobile data offloading by considering both the predictive and non-predictive cases. For the non-predictive case, we use the Lyapunov optimization technique to design the Delay-aware Network Selection Algorithm (DNSA), which yields an operation cost within O (1/V) bound of the minimum value, for any V > 0. For the predictive case, we...
Active Queue Management (AQM) design has again come into the spotlight of network operators, vendors and OS developers. This reflects the growing concern and sensitivity about the end-to-end latency perceived by today's Internet users. CoDel and PIE are two AQM mechanisms that have recently been presented and discussed in the IRTF and the IETF as solutions for keeping latency low. To the best of our...
In this paper, we propose G-Loc which leverages the gradient-based fingerprint map in localization. G-Loc firstly builds a gradient-based map (Gmap) by comparing RSSI values at nearby positions and runs an online extended particle filter to localize the user/device. With the robust Gmap, G-Loc can be more adaptive to the time-variant RSSI and effectively reduces the overhead in fingerprint map calibration...
This demo presents a novel multirate multicast scheme for video delivery to wireless users. We demonstrate an adaptive scheme that combines differential backlog scheduling and intelligent packet dropping, both based on local information. An important feature of this scheme is that it does not require centralized calculations. We focus on 802.11 mesh networks and we show that our solution copes efficiently...
