Abstract

The invention discloses a method for packet scheduling of a multi-hop network and a node device, wherein the method comprises the following steps of: acquiring residual time delay and follow-up routeconditions of all data packets; according to the residual time delay and following route conditions, determining the priority of the data packets; and according to the priority, allocating wireless resources to the data packets. The method has the advantages of effectively ensuring the packet scheduling of the high-capacity wireless multi-hop network meets the requirements of the data service on time delay, lowering the probability of discarding of the data packet with more residual hop counts, ensuring the fairness of the packet data services undergoing different hop counts, and avoiding waste of network resources.

Description

technical field

[0001] The invention relates to packet scheduling technology in the communication field, in particular to a multi-hop network packet scheduling method and a node device. Background technique

[0002] The wireless Mesh network (wireless mesh network) is different from the cellular network that passes through one hop to the destination node. It is essentially a multi-hop network, that is, a network in which data packets go through multiple hops from the source node to the destination node. The data flow carried by each node (Access Point, AP for short) is mainly divided into two types: the data flow experienced by a local user through one hop, and the data flow from other nodes through multiple hops. figure 1 is a wireless Mesh network topology diagram in the prior art, such as figure 1 As shown, the node AP1 not only needs to carry the data flow to the local terminal, but also carries the data flow from the main AP of the node to the node AP5 (the route of th...
