摘要： In a method for secure data transmission in a wireless mesh network, a sending node sends at least one packet to at least one forwarding node which receives the packet from the sending node and forwards the packet to one or more receiving nodes. A destination node receives the packet. A challenge is transmitted from the sending node to the forwarding node causing the forwarding node to reply both to the sending and the receiving node with a response which has transformed information about one or more of the packet/packets. The response is processed to find out whether the forwarding node is misbehaving or not by verifying whether the transformed information is equal to an information which can be or has been derived from the requested packet/packets, wherein the processing is carried out both by the sending node and the receiving node.

摘要： A method for transmitting data in a wireless radio network having a multiplicity of base stations for wirelessly sending and receiving data, wherein the base stations are wirelessly networked such that each base station can communicate wirelessly with one or more adjacent base stations. Broadcast messages are transmitted between a mobile station for wirelessly sending and/or receiving data and the base stations and broadcast messages are also forwarded between the base stations. These broadcast messages do not have an associated explicit connection between two units in the radio network. Moreover, the mobile station which receives a broadcast message can process this message regardless of the base station from which it originates. This avoids so-called “hand offs,” which are used in the prior art to associate a mobile station with a new base station when the mobile station moves out of range of the earlier base station. These hand offs result in time delays which are unacceptable in safety-critical applications. The novel method is particularly suitable for use in traffic systems, particularly in rail traffic systems, in which, by way of example, a train is controlled via a central unit using the radio network. In such applications, it is particularly important for no relatively long delays to arise in the data transmission, since otherwise the safety of the traffic system is no longer assured.
摘要翻译： 一种用于在具有用于无线发送和接收数据的多个基站的无线电网络中发送数据的方法，其中所述基站被无线地联网，使得每个基站可以与一个或多个相邻基站进行无线通信。 广播消息在用于无线发送和/或接收数据的移动台之间传送，并且基站和广播消息也在基站之间转发。 这些广播消息在无线电网络中的两个单元之间没有关联的显式连接。 此外，接收广播消息的移动台可以处理该消息，而不管发起来自哪个基站。 这避免了当现有技术中使用的所谓的“切换”，当移动站移出超出较早的基站的范围时，将移动台与新的基站相关联。 这些切断导致时间延迟，这在安全关键应用中是不可接受的。 该新颖方法特别适用于交通系统，特别是在轨道交通系统中，其中例如通过使用无线电网络的中央单元来控制列车。 在这种应用中，特别重要的是在数据传输中不会出现相对长的延迟，否则不再保证交通系统的安全性。

摘要： A method for data transmission from a first node to a second node in a communication network includes: analysing data arriving in a buffer of the first node to generate an arrival history curve describing the amounts of data arriving in the buffer over a past time period; processing the arrival history curve to generate a plurality of signals corresponding to filtered components of the wavelet transform; processing each signal in a separate neural network trained with training patterns based on previously received and buffered data to generate forecast signals for future data arrivals; recombining the forecast signals to generate an arrival forecast curve describing the amounts of data arriving in the buffer in a future period; the first node generating bandwidth reservation requests based on the arrival forecast curve and transmitting the bandwidth requests to the second node; the second node allocating bandwidth based on the bandwidth requests; and transmitting data from the first node to the second node within the allocated bandwidth.
