“…Data moves from one mobile device to another trying to remain as closest as possible to the target region. Information hovering can be employed in several applications in mobile networks [21,[25][26][27]. In the subsequent text, the terms target area, hovering area, and anchor area are used interchangeably.…”

Information hovering is an information dissemination concept over a mobile set of peers which has not been investigated to the extent that other information dissemination paradigms have. It naturally appears in many vehicular network applications where information must be made available to vehicles within a confined geographical area for during some time period. One elementary strategy is to flood the area with data. Even in this case, some vehicles may never receive the content due to potential partitions created by low traffic density. In order to address this issue, in this work we propose a strategy based on epidemic routing in the hovering area, and probabilistic flooding outside it. Vehicles outside the hovering area serve as bridges towards partitions, leading to high reachability. We highlight the adaptive feature of the protocol, where the rebroadcast probability in partitions is adaptively regulated based on estimates of the density of vehicles in the hovering area. The performance of the proposed scheme is evaluated in VISSIM, using as the reference model in all simulation experiments a section of the road network in cities of Washington. The proposed protocol is shown to achieve the set design goals.

“…Such estimates are obtained using the average number of neighbors of all vehicles in the hovering area, which is in turn calculated online by means of a beaconing mechanism. The proposed scheme has been successfully applied to broadcast applications in [13] and [14].…”

Information hovering is relevant in vehicular ad hoc networks in cases where critical information needs to be made available to all vehicles in a bounded geographical area, called the hovering area, for a specific amount of time. In cases of low traffic density within the hovering area, a number of vehicles may not receive the critical information due to partitioning of the vehicular network. In previous work we proposed an information hovering scheme which increases the achieved reachability, by employing probabilistic flooding outside the hovering area. Informed vehicles outside the hovering area offer alternative paths towards the uninformed vehicles thus increasing reachability. In this work we investigate the robustness of the proposed protocol with respect to changing hovering area, transmission range of the vehicles and the message loss probability. We verify that the protocol continues to work effectively in all scenarios outperforming other approaches which have been proposed in literature. In addition, we investigate enhancements to the proposed protocol which ensure improved performance in cases of high traffic density within the hovering area. We apply probabilistic flooding within the hovering area and we observe that retransmission probabilities less than one suffice to lead to high reachability values.

“…One key limitation of existing Vehicular Applications [4][5] [6] is lack of inter vehicle communications. The majority of applications developed for vehicular environments, such as emergency brake messages, traffic jam warnings, lane change warnings, and finally yet importantly, position based routing, use context information.…”

Abstract. In this paper, we propose using Hovering Information in vehicular applications to enhance their ability to deal with the dynamics of environment. In particular, we have designed and developed architecture for vehicular applications that employs Hovering Information, and described how hovering information can be utilized in decision-making module made using fuzzy logic. The system based on Hovering Information takes advantages of both hovering and local information published by other nodes and collected from local sensors respectively. The use of Hovering Information allows obtaining dynamically updated information from surrounding nodes during travel and allows information sharing within an ad-hoc network without network infrastructure. Finally, a simulation of decision-making module based on fuzzy logic that uses hovering information as an input of fuzzy controller, has been presented to demonstrate importance of hovering information in real time applications.
