Abstract:The recent release of standards for vehicular communications will hasten the development of smart cities in the following years. 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, these networks present special features and difficulties that may require special measures. The dissemination of information may cause broadcast storms. Urban scenarios are especially sensitive to broadcast storms because of the high density of vehicles in downtown areas. They also present numerous crossroads and signal blocking due to buildings, which make dissemination more difficult than in open, almost straight interurban roadways. In this article, we discuss several options to avoid the broadcast storm problem while trying to achieve the maximum coverage of the region of interest. Specifically, we evaluate through simulations different ways to detect and take advantage of intersections and a strategy based on store-carry-forward to overcome short disconnections between groups of vehicles. Our conclusions are varied, and we propose two different solutions, depending on the requirements of the application.

“…Supporting efficient alert dissemination has been investigated in the context of multiple applications, namely distribution of alerts, warnings, or general information in VANET [3,4,6,7,8,11], in networked mobile devices [5,10,13,16,21], and in first responders ad-hoc networks [9,14,15,17,18,19]. Unlike published schemes, our ADS protocol is not tied to a certain application; it can be used in vehicular networks to improve road safety or in first responder application to enable efficient handling of disasters, etc.…”

In certain situations, there may be an urgent need to disseminate alerts without the support of communication infrastructure. For example, when a disaster like an earthquake strikes, it may cause the loss of cellular coverage, Wi-Fi hotspots, etc. In this and similar application scenarios, last mile connectivity will be needed for prompt delivery of alerts. Nearly everyone nowadays carry a smart device that is equipped with at least three communication options that do not need any infrastructure, namely, Bluetooth, Wi-Fi Ad-hoc, and Wi-Fi Direct. Despite their ability to work without infrastructure, all these options need a connection setup phase before starting data dissemination. The setup phase incurs unneeded overhead and delay, which diminish their utility in delivering time-critical data. In this paper, we propose a protocol that uses the service discovery mechanism in Wi-Fi Direct to addresses these shortcomings. The protocol embeds the alert data to be disseminated in a Wi-Fi Direct service discovery frame and stores it locally. Other devices interested in receiving alerts send service discovery requests to get updates. The protocol also takes care of forwarding the received alerts to other devices as well. The evaluations showed that the proposed protocol is capable of transmitting timely alerts.

“…We implement two mechanisms to achieve this goal. The first one is making use of an efficient multi-hop broadcast, described in [5]. The other one is making an important reduction in the number of replies, while keeping the quality of the requester's estimations.…”
