Establishing an ad hoc communication network, and priority-controlled data transmission in a rail vehicle
First Claim
1. A method for establishing communication and for transmitting data between sensors in a rail vehicle, the method comprising the following steps:
- independently forming and configuring an ad-hoc network having the sensors in a network topology;
transmitting data in the rail vehicle by using the ad-hoc network;
changing the network topology over a course of the data transmission;
transmitting data configured for operational safety and data configured solely for operation over the ad-hoc network; and
providing a part-network topology formed by sensors configured solely for operation within the network topology and additionally directing the data configured for operational safety over the part-network topology formed by sensors configured solely for operation.

Abstract
A method for establishing communication and for transmitting data between sensor units in a rail vehicle uses a communication network which has multiple network nodes. An advantageous communication network and/or an advantageous data transmission can be achieved if the sensor units independently form an ad hoc network with a network topology for transmitting data in the rail vehicle, configure the network, and change the network topology over the course of the data transmission and/or if the communication network is an ad hoc network and the network nodes are sensor units. A rail vehicle including a communication network which has multiple network nodes is also provided.
