Abstract

The invention discloses a routing method based on distance weighting and its node routing function module. The node routing function module includes: Radacat CPU, GPS / Beidou module, map module, weighted distance calculation module, routing table module and RF transceiver module , the GPS / Beidou module, the map module, the weighted distance calculation module, the routing table module and the RF transceiver module are connected to the Radacat CPU. The present invention calculates a reasonable wireless communication distance through weighted calculation, and can more accurately display the relative distance between two nodes. In the distance forwarding protocol based on GPS position assistance, using this technology is more reasonable and more accurate. It can make the Mesh network forward more accurate correct forwarding messages.

Description

Technical field

[0001] The invention relates to the technical field of a wireless network multi-node dynamic routing method, in particular to a distance-weighted routing method and a node routing function module. Background technique

[0002] There are multiple nodes in a wireless network, and the nodes are dynamically moving, so how to implement a dynamic routing method for multiple nodes is a key technical point of the wireless network. The earliest wireless network developed from the Ad-Hoc network, and evolved into a complex wireless Mesh network that can communicate with other networks.

[0003] There are many wireless network routing methods. Some are based on the least hops, the fastest, and some are based on location. The location-based distance routing protocol is relatively simple, especially in wireless networks with limited bandwidth. It is not necessary to broadcast the heartbeat responsible for the whole network, and only need to exchange the GPS location, so it has ...
