Static mesh network, aircraft and method for data communication

摘要

The present invention discloses a static mesh network in or for a cabin of a vehicle, in particular an aircraft, the cabin having a predetermined, known cabin layout, comprising at least three different network levels which are arranged hierarchically in relation to one another, respectively adjacent network levels in the hierarchy being in wireless communicative connection with one another, and comprising a plurality of network nodes which operate mutually independently and of which the position in the cabin layout is fixedly predetermined by the configuration of a respective network node, the network nodes within a respective network level having an equal logic. The present invention furthermore discloses an aircraft and a method for data communication using such a network in an aircraft.

1. A method for data communication between network nodes of a static, hierarchical mesh network, constructed with a dynamic configuration, in a vehicle, comprising steps of:
(a) providing data which are coupled into a highest network level via an external interface and which are intended to be transmitted to network nodes of a lowest network level (b) transmitting the data to a first network node of a central network level, which first network node is adjacent to the highest network level, until said first network node has received all of the data; (c) transmitting the data from the first network node of the central network level to at least one second network node of the same central network level, which second network node is adjacent to the first network node until said second network node has received all of the data; (d) repeating step (c) until all of the network nodes of the central network level have received the data; and (e) simultaneously with steps (a) to (c) transmitting the data from the network nodes of the central network level to the network nodes which are respectively associated with said nodes in the lowest network level.
