Hovering Information - Self-Organising Information that Finds its Own Storage1

A piece of Hovering Information is a geo-localized information residing in a highly dynamic environment such as a mobile ad hoc network. This information is attached to a geographical point, called the anchor location, and to its vicinity area, called anchor area. A piece of hovering information is responsible for keeping itself alive, available and accessible to other devices within its anchor area. Hovering information uses mechanisms such as active hopping, replication and dissemination among mobile nodes to satisfy the above requirements. It does not rely on any central server. This paper presents the hovering information concept and discusses results of simulations performed for two algorithms aiming to ensure the availability of a piece of hovering information at its anchor area.
