| 20100180113 | METHOD FOR MISBEHAVIOUR DETECTION IN SECURE WIRELESS MESH NETWORKS - 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. | 07-15-2010 |
| 20100195535 | Methods, Networks and Network Nodes for Selecting a Route - The invention relates to methods, networks and network nodes for setting up a route in a packet-switched network comprising network nodes which are connected to one another for data engineering purposes, where the route connects a starting node to a destination node through intermediate nodes. The route is set up with a distance correlation to a reference route which has already been set up in the network. | 08-05-2010 |
| 20100260153 | METHOD FOR DATA TRANSMISSION IN A MESH MODE OF A WIRELESS COMMUNICATION NETWORK - In a method for data transmission in a mesh mode of a wireless communication network, which enables a decentralized transmission of data packets within data streams via communication links from one node to another node, data streams are classified in several service classes specifying quality requirements for data streams. Bandwidth reservations are performed between nodes of a communication link, each bandwidth reservation being dependent on the service class of the data stream to be transmitted via the communication link and comprising the exchange of control messages for reserving time slots for transmitting the data stream of the service class in subsequent data time frames via the communication link. The transmission of data streams is scheduled dependent on the service classes. The method is particularly used in the mesh mode of the standard IEEE 802.16 and enables a seamless coexistence of the point-to-multipoint mode and the mesh mode of the standard. | 10-14-2010 |
