The invention discloses a lightweight routing design method and
system suitable for a chain
broadband wireless ad hoc network. The
system comprises a configuration network node, a definition node
routing architecture, a data packet classifier module configured in the node, a
delay module, a general module, a neighbor
list module, a neighbor information manager module, a
delay estimator module, a data packet
queue module, a
queue processing module, an MAC
receiver module and an MAC
transmitter module. The method comprises the following steps: calculating queues of
delay data packets and general data packets according to data frame structure classification; regularly updating a neighbor
list according to the data packets of the adjacency relationship; estimating the time required by local
queue transmission; and queuing the delay data and the general data according to the priority, and establishing a forwarding link. According to the invention, the nodes automatically complete path planning and queue ordering in real time according to a
routing protocol architecture, unified and centralized scheduling by an upper-layer
route is not needed, and network resources are not occupied. According to the method, node resources are utilized to the greatest extent on the basis of ensuring communication delay.
