Definitions

  • the invention relates to dynamic networks that result from the fact that, for example, vehicles use radio technology to establish connections.
  • Vehicles are primarily intended for road-bound vehicles, for example PK s, but they can also be ships or even
  • Airplanes act.
  • Such so-called ad-hoc networks for mobile participants are subject to very strong changes in their networks, due to the high fluctuation of the participants due to the normally moving vehicles with different destinations and directions.
  • the object on which the invention is based is now to specify a method and a device for an ad hoc network with mobile subscribers, in which a better transmission quality or a lower transmission bandwidth is required with a fixed predetermined bandwidth or with the same transmission quality.
  • the invention essentially consists in the fact that the active inclusion of driving condition data of vehicles in the area as well as static traffic flow data, dynamic traffic flow data, topographical information and topological information builds up connection paths in such a way that the network structure is possible, despite the high fluctuation of the participants stable and, because of the lower number of connection changes, the transmission quality or the use of the specified bandwidth is improved.
  • the drawing shows an example of a section of an ad hoc network for mobile subscribers, in which a connection from a mobile node A to a further mobile node B can be connected either via a mobile neighboring node H1 or a further mobile neighboring node H2 (hop), where these nodes represent so-called switching nodes (hops) and in the switching node H2 a further switching takes place either via a switching node H21 or via a switching node H22 to the destination node B.
  • the mobile neighboring node H1 sends its driving status data, for example its position, general acceleration data, its direction, its destination, its driver profile etc. to the mobile node A.
  • this also takes place from the mobile switching node H2, which sends its driving status data D2 to the node A.
  • the data D1 or D2 can be transmitted from the neighboring node to the output node A, for example, by simply streaming this data with a certain range only on certain frequencies, which means that Information is available to all receivers in the area for evaluation.
  • the driving state data it is also conceivable for the driving state data to be forwarded simply via broadcastmg or multicastmg in the network via a certain number of switching nodes or else intelligently depending on the distance.
  • the mobile node A When setting up these ad hoc networks, it is always up to the decision with which neighbor a link is established or via which link data is forwarded / routed.
  • the mobile node A receives additional information about its surroundings and / or about the surroundings of its mobile neighboring nodes from a local memory located in the node A, or it receives current additional information, for example from one
  • Traffic control center VL which is streamed via a geographically fixed transmission station, for example, or is offered as a service on the network.
  • the additional information in node A is used to determine a likely future development of the transmission quality to the respective neighboring node, as explained in more detail below, and a connection is established for forwarding information about the neighboring node via which the likely future node Development of broadcast quality is best.
  • Static traffic flow data which were determined from statistical averages from measured traffic flows in the past. Such a flow of traffic either has only an amount or it also has a direction. For example, the fact that a continuous movement of the mobile nodes on developed roads, such as highways, is higher than on secondary roads and so that a routing structure can be kept more stable than on secondary roads. 2. Dynamic traffic flow data:
  • dynamic traffic flow data for example, which originates, for example, from a traffic control system and is streamed in a specific range, can optionally be used as current additional information.
  • topological information such as city maps or street maps can also serve as additional information.
  • This information and the driving state information D, D1 and D2 can be used, for example, to determine whether the mobile neighboring nodes or vehicles will probably move in the future on the same lane, on a cross street or on an opposite lane.
  • the routing structure is more stable than in a situation in which the neighboring node is moving in the direction of a cross street or, in an even worse case, on the opposite lane.
  • Topographical information can also optionally be used as additional information for evaluation. This includes, for example, probable terrain changes in the vicinity of the moving node or obstacles, for example in the form of buildings and tunnels. It is assumed here that the routing structure cannot be kept stable to the extent that these terrain changes or shadows through buildings or tunnel entrances are possible than when switching via switching nodes that move on open terrain.
  • a probable future development of the transmission quality to the respective neighboring node is determined from the driving state data of the mobile neighboring nodes H1 and H2 and the additional information, and a connection is established via the neighboring node via which the probable future development of the transmission quality can best take place.
  • Such selection mechanisms are conceivable not only in the output node A, but also in downstream switching nodes, for example the node H2 with its neighboring nodes H21 and H22.
  • node A is not only informed of the driving status data of the mobile neighboring nodes, but also of the driving status data of several or all switching nodes located in the respective transmission paths, for example H21 or H22, and that these are also formed from node A when the transmission paths are formed be taken into account.

Abstract

L'invention consiste sensiblement en ce que la prise en compte active de données d'état de marche de l'environnement, ainsi que des données de flux de trafic statiques permettent de produire des données de flux de trafic dynamiques, des informations topographiques et des chemins de liaison prévoyant des informations topographiques, de manière que la structure du réseau, en dépit de fluctuation élevées des abonnés, soit la plus stable possible et que par conséquent, en dépit du nombre plus petit d'échanges de liaison, la qualité de transmission et la largeur de bande soient améliorées.
