摘要： In order to create a non-wired network, a first communication appliance is provided with a list of identifiers of other communication appliances with which connections can be established. The first communication appliance determines information on the local topology of the non-wired communication network from the identifiers of the other communication appliances. The first communication appliance establishes a connection with the isolated, thus collected, partial networks and individual communication appliances, and integrates the same into the network.

摘要： According to the known IEEE 802.11s Draft Standard for WLAN Mesh Networking, version D5.0, the size of an information element is restricted to a length of 255 octets. Due to the definition of an MCCAOP advertisements element as a general information element this restriction is a major drawback leading to a maximum of 62 MCCA reservations to be advertised by an MCCAOP advertisements element. Although this number of reservations might be sufficient in the majority of situations, it is easily imaginable that there are situations which could require an advertisement exceeding this limit of 62 MCCA reservations. According to the disclosure, an MCCAOP advertisement—which is a set of MCCAOP reservations that needs to be advertised—is split over multiple MCCAOP advertisements elements. This may advantageously allow advertising more than 62 MCCAOP reservations to neighboring mesh nodes in a wireless mesh network which is configured to use MCCA.

摘要翻译： 根据已知的IEEE 802.11s WLAN Mesh网络草案，版本D5.0，信息元素的大小被限制为255个八位字节的长度。 由于MCCAOP广告元素作为一般信息元素的定义，该限制是导致由MCCAOP广告元素发布的最多62个MCCA预留的主要缺点。 尽管在大多数情况下，这种保留可能已经足够了，但是很容易想到有可能需要超过62个MCCA保留限制的广告的情况。 根据本公开，MCCAOP广告（其是需要被通告的一组MCCAOP预约）被分解在多个MCCAOP广告元素上。 这可以有利地允许在配置为使用MCCA的无线网状网络中广告超过62个MCCAOP预留到相邻网格节点。

摘要： In a method for exchanging routing messages in a wireless meshed communication network with network nodes and a root node, a routing tree is set up with data transmission paths. The root node sends routing requests at regular time intervals to set up the paths, wherein a request contains a specification for a first bidirectional path mode or a second unidirectional path mode. At a respective node, a first field is used to indicate a first or a second node state. If, upon receipt of a request, the first field is in the first state, a routing response is always sent and otherwise not. Next, the node checks the mode specified in the request, ensuring that the respective mode is set. In case of a node to root data transmission, a node also ensures that the first field of the respective network node is in the first state.

摘要： Route discovery of a route from a source node of an IEEE 802 connection to a destination node of an IEEE 802 connection, including a mesh network path with a source node of the mesh path and a destination node of the mesh path, is initiated by an extended route request message generated by the destination node. The extended route request message includes a flag that indicates whether the source node of the IEEE 802 connection is located inside or outside the mesh network, and either one source address of the source node, if the node is inside the mesh network, or two source addresses covering (a) the source address of the source node of the mesh path and (b) the source address of the source node of the IEEE 802 connection, if the node is outside the mesh network.

摘要： A method for data transmission in a local are network, wherein data is transmitted on the Media Access Control (MAC) layer within successive time frames between a plurality of first nodes comprising client nodes to a second node comprising a coordinator node for the plurality of first nodes. A synchronizing slot for sending a synchronizing message from the second node to the first nodes includes acknowledgements for time slots used for data transmissions in previous time frames from the first nodes to the second node. The acknowledgements indicate whether a data transmission in the previous time frame was successful. Based on these acknowledgements, retransmission time slots included in the current time frame are used for retransmitting data that have not been transmitted successfully in a time slot of the previous time frame.
