example

[0088] refer to figure 2 , each node in the network maintains a routing table of one-hop nodes with itself as the center, including a multiplexing area and a diversity area, and the areas overlap each other. The source node A uses the multiplexing method to exchange MULTIPLEXING_SOP control frames in each multiplexing cycle, and maintains the nodes C, D, and F in its multiplexing area, and uses the diversity method to exchange DIVERSITY_SOP control frames in the diversity cycle to maintain its diversity area. Nodes B, E, H, J, N of . Nodes B, E, H, J, and N are all reachable nodes from source node A, and the update of routing entries depends on the policy described in step 2.

[0089] If the service generated by the source node A belongs to the dual area, query the routing table to send the data service. If there are two routing information to the destination node of the data service in the routing table, the optimal routing information is selected as the actual sending rou...

Abstract

The invention discloses a MIMO link-based routing addressing method, belonging to the technical field of wireless communication. The method comprises the following steps: initializing a routing table and transmitting routing information according to the Metric formula of a modified MIR router and the Metric formula of a load balancing router; establishing a diversity and multiplex dual district according to the received routing information; for the data generated by any node, inquiring the routing table, transmitting if the routing table comprises the routing information of the target node ofthe data, otherwise margin broadcasting the routing request; receiving the node of the routing request and judging comprising the routing information achieving the target node according to the routingtable, if yes, replying by the router, otherwise continuing margin broadcasting the routing request into the network; receiving the node replied by the router and judging whether itself is the original node, if yes, carrying out dual district external data transmitting, otherwise transmitting the router reply to the original node. The invention has the advantages of high signal path utilization rate and low collision rate, and can be used in large-scale wireless distributed network.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a routing addressing method based on MIMO technology, which can be used in large-scale wireless distributed networks. Background technique [0002] In a wireless distributed network, an effective routing addressing method is crucial to the performance of the entire network. To solve the routing problem, there are usually several algorithms such as proactive routing, reactive routing, and auxiliary routing based on geographic location information. However, when the network scale increases or the network topology changes frequently, the addressing methods proposed based on these basic routing algorithms are not ideal. In the document "A new routing protocol for the reconfigurable wireless networks", a zone routing protocol suitable for large-scale wireless distributed networks is proposed, namely the ZRP protocol. The ZRP protocol is a hybrid routing protocol that ...
