A common assumption in intermittently-connected (or opportunistic) mobile networks is that any contact has enough capacity to transfer the required amount of data. Although such an assumption is reasonable for analytical purposes and when contents are small, it does not hold anymore when nodes produce contents that are larger than the capacity of a contact.(More)
1. CONTEXT AND MOTIVATION Enabling content sharing among mobile users is a promising application for opportunistic networks. Clearly, collo-cated people are likely to share mutual interests. In this context, disseminating contents through opportunistic communications could be more efficient than passing through central servers. We implemented PACS(More)
—Lithium-ion batteries, widely used in electric vehicles (EVs), have a specific charging profile where the power consumed varies over time and defines the amount of power the charging station needs to deliver. Achieving a proper tradeoff between charging levels, number of vehicles, and electric capacity of the plant is challenging. In order to give a solid(More)
Passengers enjoy browsing the Internet and using social networking applications while commuting throughout the city. Nevertheless, it is not always possible to access the Internet at will. First, cellular coverage can be poor or nonexistent in some areas. Second, cellular communications may be expensive for a significant share of the population. Finding(More)
In vehicular networking, contacts have short duration and may seldom occur. Hence, maximizing the amount of data transferred per contact opportunity is of utmost importance. In this work, we propose TraC which combines network nodes caching, typically used in Content-Centric Networks (CCNs), and users' trajectory knowledge. The idea is to improve data(More)
Urban mobility became a major challenge around the world, with frequent congestion and ever growing travel time. Albeit recent advances in the area of Intelligent Transportation Systems (ITS), it is still difficult to predict and manage the road infrastructure due to dynamics and instability of the traffic. One key issue is how, given some traffic(More)
Most cities in the Amazon have no data communication infrastructure, and rivers are most of the time the only access mode to connect small cities to urban centers. In this paper, we investigate the deployment of vehicular ad hoc networks (VANETs) formed by boats along the rivers of the Amazon as an alternative to interconnect the small cities to the capital(More)
