Problems solved by technology

However, in this case, in order to coordinate the transmission between network nodes, some new protocols need to be adopted; the second type is multi-channel multi-transceiver MAC protocol, in this network environment, each node contains multiple radio frequency units And baseband processing module, to support multiple channels to run at the same time, there is only one MAC layer on the physical layer to coordinate the function of multiple channels, but how to design an effective MAC protocol for this physical layer platform is still unresolved, this In this case, a new MAC protocol is required, and the existing network card itself needs to be modified; in summary, the solutions of the prior art all need to modify or supplement the MAC layer protocol of the existing network card, that is, the hardware device needs to be changed. Existing investment in current equipment is a loss

Embodiment Construction

[0028] The present invention performs secondary scheduling on services accessed through 802.11e on the basis of the dual-network card scheme. The general idea of ​​the scheme is as follows: First, configure dual transceivers for each node. Network card; then, connect the 802.11a and 802.11b network cards respectively according to the service priority defined by 802.11e, where the service received by the receiving end through the 802.11a network card is the service that needs to be forwarded by the node, and the service received by the receiving end through the 802.11b network card It is a local service within the coverage of the node; then, the two-way service is scheduled for the second time; finally, the service sent by the sending end through the 802.11a network card is the service to be forwarded by other nodes or directly connected to the core network Service, the service sent by the sender through the 802.11b network card is the local service within the coverage of the no...

Abstract

Being applicable to nodes in wireless mesh network, the system includes dual transceivers collocated for node, and despatcher connected to the said dual transceivers. The method includes collocating dual transceivers for each node, and connecting the dual transceivers to service; carrying out second time of deployment for the said service, and sending out the service after the said second time of deployment. The disclosed system and method can distinguish priorities for diversified services so as to realize equitable access, guarantee quality of service, and reach optimal performance of system.

Description

technical field [0001] The present invention relates to a system and method for service dispatching, in particular to a system and method for service dispatching in a wireless mesh network. Background technique [0002] Wireless Mesh Network WMN (Wireless Mesh Network) is a new type of broadband wireless network structure, that is, a high-capacity, high-speed distributed network, which is different from traditional wireless networks. All users of a traditional wireless local area network (WLAN) access the Internet through a traditional wireless access point AP (Access Point), but WLAN only allows users within the single-hop range of the AP to access, while a single-hop network The coverage area is very limited, so the number of users is very limited. In order to greatly expand the coverage of the network, a multi-hop network structure must be adopted, that is, a data sent from the source node may be forwarded by several intermediate nodes before reaching the destination nod...
