Embodiment Construction

[0057] In order to explain the preferred embodiment of the present invention below, it is assumed that the communication network is a VANET formed between a plurality of mobile nodes, such as vehicles, and stationary nodes, such as roadside units. It is assumed that so-called vehicle-to-vehicle communication (V2V; mobile node to mobile node) and vehicle-to-infrastructure communication (V2I; mobile to fixed) is possible. Furthermore, it is assumed that a mobile node such as a vehicle is equipped with a device for specifying the current position, for example, a positioning system (for example, GPS or GALILEO) configured to specify the position of each vehicle in real time. However, the invention is not limited to this network structure, and can be applied to a network, in particular a wireless network of multiple network nodes, for communicating via multi-hop in a communication network, especially a mobile ad-hoc network or a vehicle mobile ad-hoc network Data packets are transm...

Abstract

The present invention relates to a method and an apparatus for disseminating a data packet in a communication network, in particular a mobile ad-hoc network, comprising a plurality of network nodes. At a first receiving node (F1), a data packet sent from a sending node (S) is received and the position of the receiving node (F1) is determined. According to the invention, a forwarding area (BS1) is determined based on the position of the destination (D); and the data packet is forwarded to one or more neighbor nodes of the first receiving node (F1), if the first receiving node (F1) is located inside the determined forwarding area (BS1).

Description

technical field [0001] The invention relates to a method for communicating via multi-hop communication in a communication network, in particular in a mobile ad-hoc network (ad hoc network) MANET or a vehicle mobile ad-hoc network VANET comprising a plurality of network nodes, especially mobile nodes Method and apparatus for destination transmission of data packets. At a first receiving node, a data packet sent from a source node is received, wherein the data packet includes source location data indicating the location of the source node, and first recipient location data is determined, wherein the first recipient location data indicates a first The location of the receiving node. [0002] In particular, the present invention relates to a method for use in a mobile ad-hoc network MANET or a vehicle mobile ad-hoc network VANET by flooding data packets between nodes of a communication network for information transmission via so-called multi-hop communication Method and apparatu...
