Predicting users' next location allows to anticipate their future context, thus providing additional time to be ready for that context and react consequently. This work is focused on a set of LZ-based algorithms (LZ, LeZi Update and Active LeZi) capable of learning mobility patterns and estimating the next location with low resource needs, which makes it(More)
Thanks to the research on Vehicular Ad Hoc Networks (VANETs), we will be able to deploy applications on roadways that will contribute to energy efficiency through a better planning of long trips. With this goal in mind, we have designed a gas/charging station advertising system, which takes advantage of the broadcast nature of the network. We have found(More)
Road safety has become a main issue for governments and car manufacturers in the last twenty years. The concept of Intelligent Transportation Systems (ITS) is used when talking about communication technologies between vehicles and infrastructure to improve, among others, road safety. In this paper, we propose a warning service to prevent accidents by(More)
Wireless communications amongst vehicles bring the opportunity for a wide range of applications, from safety aid to passenger entertainment. The necessity to broadcast information to several-hop neighbors is common to most of the potential application protocols. Broadcast protocols for VANETs based on diverse techniques have already been proposed. In this(More)
Many applications for vehicular networks, such as blocked road warnings or advertising, will require multi-hop dissemination of information to all vehicles in a region of interest. However, this type of communication can cause broadcast storms. Urban scenarios are especially sensitive to broadcast storms because of the high density of vehicles in downtown(More)
Many modern devices come with several, heterogeneous, network interface cards (NICs). However, simple operations like transferring data flows to the cheapest NIC or to one with enough Quality of Service (QoS) are awkward tasks on most Operating Systems. In this paper, we discuss the criteria to select the proper NIC for a given data flow. We also present a(More)
The authors recently reported that CD2 ligation rescues B cells from antigen-induced apoptosis by upregulation of intracellular Bcl-2 levels. However, the characterization of the early signals involved in apoptosis rescue by CD2 ligation has not been well established. In this context, CD2 does not promote either phosphatidylinositol turnover or CA2+(More)
