Abstract

The invention discloses a route addressing method and device for selective transmission, belongs to the technical field of wireless communication and mainly solves the problem that in a wireless distributed network, the times of repeatedly forwarding route request messages is excessive. The method comprises the steps of determining channel information; determining neighbor nodes and the optimum hop distance of each node according to the obtained channel information; determining coverage range parameters Rs and Rb according to the optimum hop distance; adjusting the Rs and Rb according to demands and determining a connection relationship among the nodes according to the determined Rs and Rb, wherein the connection relationship comprises short distance direct connection, relay direct connection and indirect connection; and when the nodes send or forward the route request messages, detecting the connection relationship between current nodes and destination nodes, and determining that the route request messages are sent or forwarded to which nodes.

Description

Technical field: [0001] The invention relates to the technical field of wireless communication, in particular to a routing addressing method, which can be used in large-scale wireless distributed networks. Background technique: [0002] With the popularization of wireless communication devices, various wireless communication applications are favored by people, but the explosive growth of wireless communication devices also brings challenges to traditional communication systems. For example, with the increase of wireless devices, blind spots in base stations lead to strong signals in some places, weak signals in some places, and even no signal at all. When natural disasters such as earthquakes occur, large-scale base station equipment or power systems are easily damaged, resulting in communication failures between wireless communication devices. On the battlefield, the lack of infrastructure such as its own base station or the high cost of building infrastructure also hinder...
