Routing method and routing apparatus

Abstract

The embodiment of the invention discloses a routing method and a routing apparatus. In the embodiment of the invention, a first Mesh node going to perform routing acquires energy consumption information of at least two second Mesh nodes, wherein the second Mesh nodes are capable of providing route for the first Mesh node; and the first Mesh node performs routing according to the energy consumption information of the at least two second Mesh nodes. Thus, available time of a Mesh network can be prolonged.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a routing selection method and device. Background technique [0002] Mesh networks have the advantages of wide coverage, low deployment costs, and convenient access, so they have extremely broad application prospects. For example, Mesh network technology is commonly used in the Internet of Things. [0003] Each Mesh node to be routed in the Mesh network performs routing based on the signal strength of the Mesh node that can provide routing. For example, a client (Client) generally accesses a wireless access point with a stronger signal ( Access Point, AP). However, each Mesh node in the Mesh network performs routing selection based on the size of the signal strength, which may cause unbalanced energy usage of the Mesh network and reduce the available time of the Mesh network. For example, there are currently four Clients and two APs. The four Clients are c1, c2, c3, a...

Problems solved by technology

However, each Mesh node in the Mesh network performs routing selection based on the size of the signal strength, which may lead to unbalanced energy usage of the Mesh network and reduce the available time of the Mesh network.

For example, there are currently four Clients and two APs. The four Clients are c1, c2, c3, and c4, and the two APs are AP1 and AP2. For c1 and c2, the signal strength of AP1 is stronger than that of AP2. For c3 and c4, the signal strengths of AP1 and AP2 are equivalent, but the signal strength of AP1 is slightly stronger than that of AP2, so the routing decision based on the signal strength is adopted, c1, c2, c3 and c4 will be connected to AP1, The load of AP1 is significantly higher than that of AP2, and the energy consumption of AP1 is accelerated, while AP2 has no energy consumption, resulting in unbalanced energy consumption

When AP1 runs out of energy, c1 and c2 need to connect to AP2, which is farther away, which consumes more energy than connecting to AP1, resulting in an increase in the overall power consumption of the Mesh network and reducing the available time of the Mesh network
