Wireless communication network, communication method and node used in wireless communication network

摘要

A wireless communication network, a communication method and a node for the wireless communication network are disclosed. The wireless communication network includes a plurality of peer nodes communicating with each other through a control channel and a plurality of data channels. The communication method may include: transmitting available data channel information via a routing request signal; modifying available data channel information received by the source node or the other intermediate nodes, and transmits the modified available data channel information via a routing request signal; determining an agreed data channel for communication between the destination node and the source node or between the destination node and the intermediate node, according to the available data channel information transmitted from the source node or the intermediate node; and notifying an intermediate node as a previous hop and/or the source node of an identification of the agreed data channel via a routing response signal.

1. A communication method used in a wireless communication network, the wireless communication network comprising a plurality of peer nodes, the plurality of peer nodes communicating with each other through a control channel and a plurality of data channels, the communication method comprising:
transmitting, by a source node among the plurality of peer nodes, available data channel information indicating information on a plurality of available data channels via a routing request signal; modifying, by an intermediate node among the plurality of peer nodes, the available data channel information received by the source node or the other intermediate nodes, and transmitting the modified available data channel information via the routing request signal; selecting, by a destination node among the plurality of peer nodes, an agreed data channel for communication between the destination node and the source node or between the destination node and the intermediate node from the plurality of available data channels, according to the available data channel information transmitted from the source node or the intermediate node; and notifying, by the destination node, the source node of an identification of the agreed data channel via a routing response signal; or notifying, respectively by the destination node and the intermediate node, a node as a previous hop thereof of the identification of the agreed data channel via the routing response signal, wherein the available data channel information comprises the identification of each of the plurality of available data channels and a respective priority index value, modifying the available data channel information comprises modifying the priority index value of available data channels, and selecting the agreed data channel for communication between the destination node and the source node or between the destination node and the intermediate node comprises: computing, by the destination node, a new priority index value according to the priority index value of available data channel received from the source node or the intermediate node, and determining the available channel of the highest priority index value as the agreed data channel.
