Method for balancing loads of ad-hoc network gateways

Abstract

The invention discloses a method for balancing loads of ad-hoc network gateways and is applicable to a tree type ad-hoc network which is established by taking all gateways as the root. The method is characterized by comprising the following steps that: a first node receives the current load information of candidate gateways, wherein the candidate gateways comprise current gateways of the first node and gateways of adjacent trees; the first node selects effective gateways according to the maximum support load information of the candidate gateways, the current load information and load information which is required to be forwarded by the first node; and the first node forwards the load information which is required to be forwarded by the first node to the effective gateways. According to the invention, in a mode of selecting the effective gateways by the first node according to the load information of the candidate gateways, the flexibility and self-adaptability of the ad-hoc network are improved, and the loads of the ad-hoc network gateways can be dynamically balanced.

Description

technical field [0001] The invention relates to the field of network communication, in particular to an ad hoc network gateway load balancing method. Background technique [0002] In existing life, due to environmental constraints, wired network communication cannot be used in many cases. For example, a network installed under a mine. Due to the poor production conditions and backward mining technology, mine accidents such as roof fall accidents occur frequently. If a wired communication network is used under the mine, when an accident occurs, it is easy to cause the network to be paralyzed. Moreover, the roads under the mine are intricate, and the use of wired methods will inevitably lead to intricate connection lines, which are not easy to maintain. Therefore, in the prior art, a wireless-based ad hoc network is used under the mine, and then the gateway in the ad hoc network communicates with the wired network on the ground. Due to the multi-hop aggregation effect of t...

Problems solved by technology

However, this method reduces the flexibility and adaptability of the ad hoc network. For example, sometimes a certain gateway receives a large amount of packets, exceeding its maximum load, while the other gateway is in an idle state. , the message cannot be forwarded to the idle gateway, therefore, the maximum benefit of the gateway cannot be realized

[0003] Moreover, in the prior art, the nodes use the gateway as the destination address to forward the message, which cannot realize the load balancing of each radio frequency in the gateway
