Description

technical field

[0001] The invention relates to the technical field of wireless network optimization method design, in particular to a wireless network optimization method for an intelligent meter reading system that is fast, accurate, efficient and scalable. Background technique

[0002] In recent years, WLAN has developed rapidly in the field of access. According to its huge data transmission rate, WLAN is considered to be a major competitor in the mobile data communication part. However, WLAN itself also has its shortcomings, the most important of which is that the coverage of the access point (AP) is relatively limited. If you want to provide wireless coverage in a relatively large area, you need to configure multiple APs in the area. Access points, thus increasing the cost of building a WLAN-based public broadband network. Although people have proposed some solutions, such as improving unlimited coverage and location adaptability through the coexistence of multiple wir...

Embodiment Construction

[0055] Below with the accompanying drawings Figure 1-7 The present invention is described in further detail.

[0056] DSR is a peer-to-peer, topology-based reactive ad hoc routing protocol. It is characterized by an aggressive caching strategy and extraction of topology information from source routing. The DSR protocol includes two processes: route discovery and route maintenance. The route discovery process uses flooded routes. In order to reduce the cost of the route discovery process, each node includes a buffer to store the most recently used routing information. The route maintenance process is the mechanism used by the source node to detect whether the network topology has changed. If the topology changes and the source routing is interrupted, the source node will receive routing error information. It will try to use the routing information in the cache, and restart the routing discovery process if it is different.
