figure 2
In the scenario shown in , with a mobile radio FT* of a train T*, another radio FTCC* of a line-side monitoring and control unit TCC* and a chain K* of 20 nodes, according to the computer simulation used, Interference causes up to 5.63% packet loss
Computer simulations for other scenarios with two mobile radios (2-train scenario) yielded up to 20% packet loss

Embodiment Construction
[0043] image 3 Shown is a communication network KN according to the invention without a network backbone, which is suitably configured for a mobile radio device FT of one communication participant TC and a further radio device of another communication participant TCC Between FTCCs, a continuous communication connection is guaranteed.
[0044] The one communication partner TC shown here is installed in a vehicle, here a rail vehicle in the form of a train T. In this case, the one communication partner TC is the vehicle-side monitoring and control unit, which can provide the mobile radio FT with the data packets to be sent via the connection shown, or receive the mobile radio FT. Packets received by the device.
[0045] The other communication participant TCC shown here is a line-side monitoring and control unit. The line-side monitoring and control unit can be connected to one of the further radio devices Fi* in a data-appropriate manner in order to deliver data packets to ...

The invention relates to a communication network (KN), in particular an ad hoc communication network having at least one mobile wireless device (FT) and having a plurality (m) of further wireless devices (F1,..., Fm) installed on a line (S). In order to exclude or to minimize data packet losses in the communication network (KN), according to the invention, a respective wireless device (Fi) of thefurther wireless devices is suitably designed to operate in each of the two directions (R1, R2) of the line (S) for communication with other wireless devices of the further wireless devices of a respective wireless channel pair (A or B or C), the mobile wireless device is suitably designed to operate all wireless channels (K1, K2, K3) of the wireless channel pair (A, B, C) exclusively for receiving data, in particular from the further wireless devices (F1,..., Fm), an additional wireless channel (K4) is provided, the mobile wireless device is suitably designed to operate the additional wireless channel (K4) exclusively for transmitting data, in particular to the further wireless devices (F1,..., Fm), and the further wireless devices (F1,..., Fm) are suitably designed to operate the additional wireless channel (K4) exclusively for receiving data, in particular from the mobile wireless device (FT). The invention further relates to a method for operating a communication network.
Description
technical field [0001] The invention relates to a communication network, in particular an ad-hoc communication network, having at least one mobile radio and having a plurality of further radios installed on the line. Background technique [0002] In the applicant's earlier German patent application, which has been filed under application number 10 2017 203 040.2 (DE), a general communication network is described which is configured as an ad hoc communication network. In two of the embodiments of the ad hoc communication network described there, a respective one of the further radio devices is suitably configured for communicating with the corresponding radio in each of the two directions of the line The other radios of the other radios of the channel pair communicate. [0003] figure 1 Also shown is a communication network KN* in the form of an ad hoc communication network with a mobile radio FT* and with a plurality of further radios Fi* installed on the line, which are a...
