Abstract

The invention discloses a distance-weighting-based routing algorithm and a node-routing functional module thereof. The node-routing functional module comprises a Radacat CPU (Central Processing Unit),a GPS (Global Positioning System) / Beidou module, a map module, a weighting distance calculation module, a routing list module and an RF (Radio Frequency) receiving and transmitting module, wherein the GPS / Beidou module, the map module, the weighting distance calculation module,, the routing list module and the RF receiving and transmitting module, are connected to the Radacat CPU. The distance-weighting-based routing algorithm disclosed by the invention calculates a reasonable wireless communication distance through weighing calculation so as to display a relative distance between two nodes more accurately; in a GPS position aid-based distance forwarding protocol, the technology is used more reasonably; and a more accurate distance can enable a Mesh network to forward a more accurate correctness forwarding message.

Description

technical field

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

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

[0003] There are many wireless network routing algorithms, including those based on the least number of hops, those based on the fastest speed, and those based on location. Among them, the distance routing protocol based on location is relatively simple, especially in wireless networks with limited bandwidth. It does not need to broadcast the responsible heartbeat on t...
