Embodiment Construction

[0067] FIG. 1 shows a communication device 100 for communication between mobile nodes, ie communication between vehicles 10, 12, 14, 16 (see FIGS. 2A, 2B and 2C).

[0068] The communication device 100 includes

[0069] - a transmitting unit 20 for communicating, ie broadcasting and rebroadcasting, a message 22; and

[0070] - A receiving unit 30 for sensing arrival messages 32 , 34 , 36 communicated by neighboring vehicles 12 , 14 , 16 .

[0071] Connect the transmitting unit 20 and receiving unit 30 to:

[0072] - receiving / transmitting antenna 23; and

[0073] - a controller unit 40, i.e. a message diffusion control box, for controlling the sending behavior of the respective vehicle 10, 12, 14, 16, namely by processing the incoming messages 32, 34, 36, in particular by processing the incoming messages 32, The confirmation array of 34,36 judges whether corresponding vehicle 10,12,14,16 rebroadcasts message 32,34,36,

[0074] Additionally, connect the controller unit 40 to...

Abstract

In order to provide a communication device (100) for communication between and among mobile nodes (10, 12, 14, 16) comprising at least one transmission unit (20) for communicating at least one message (22), - at least one receiver unit (30) for sensing at least one arriving message (32, 34, 36) being communicated by at least one neighbouring node (12, 14, 16), and at least one localisation unit (60) for determining and / or for monitoring the moving direction and / or the current position of the respective node (10, 12, 14, 16), wherein the amount of broadcast messages in inter-node communication, in particular in inter-vehicle communication, is reduced, it is proposed that each message (22; 32, 34, 36) being communicated between and among the nodes (10, 12, 14, 16) is assigned to at least one message type and / or message subject and - to at least one direction area relating to the moving direction of the node (10, 12, 14, 16) by which the respective message (22; 32, 34, 36) is transmitted, the moving direction being determined and / or monitored by the localisation unit (60) of the respective node (10, 12, 14, 16).

Description

technical field [0001] The present invention relates to a communication device and method for communication between two or more mobile nodes, in particular, for communication between two or more vehicles, wherein each node is designed for: [0002] - determine and / or monitor the direction of movement and / or current position of the corresponding node [0003] - sensing an arrival message communicated by at least one neighboring node, in particular broadcast or rebroadcast, and [0004] - Communicating at least one message by broadcasting and / or rebroadcasting. Background technique [0005] Abdelmalik Bachir and Abderrahim Benslimane, "A Multicast Protocol in Ad hoc Networks Inter-Vehicle Geocast" [Proceedings of 58th IEEE Vehicular Technology Conference, Fall 2003, Vol. 57, No. 4, pp. 2456 to 2460] ] relates directly to the above technical fields and summarizes the current state of the art, which combines the current algorithms and thus becomes the so-called I[nter-]V[ehicl...
