Abstract

The invention discloses a routing method of a mobile Ad Hoc network based on navigation and positioning information, and relates to the technical field of routing of the mobile Ad Hoc network. The method comprises the following steps that: a global positioning system (GPS) radio frequency (RF) module and a GPS base band module receive the navigation and positioning information for positioning; a mobile node dynamically adjusts the transmitting / receiving direction and power of an intelligent antenna according to the positioning information and surrounding terrain information characteristics, and probably transmits and receives in all direction, or in half direction or in partial direction; and an Ad Hoc network routing module performs route discovery, route establishment and route maintenance by an Ad Hoc network positioning auxiliary dynamic routing algorithm. The method has the characteristics of short route establishment time and precise routing; when the method is applied to mountainous areas, the directional radio wave transmission is performed according to terrain characteristics and mountainous area map information, so that the electric quantity of the mobile node is saved, and the availability of the mobile Ad Hoc network is improved.

Description

technical field [0001] The invention relates to a routing method for a mobile ad hoc network with location assistance, in particular to a routing method for a mobile ad hoc network based on navigation and positioning information, and belongs to the technical field of wireless ad hoc network routing. Background technique [0002] Traditional mobile ad hoc network routing protocols mainly include DSR (Dynamic Source Routing Protocol), AODV (Ad Hoc Network On-Demand Distance Vector Routing Protocol), DSDV (Destination Sequential Distance Vector Routing Protocol) and so on. Due to the broadcast nature of route discovery and when the path is long, the route is easily invalidated, resulting in a large amount of routing overhead, so one of their main disadvantages is that they are not suitable for medium-to-large-scale, medium-to-high-speed movement occasions. Therefore, many location-based routing protocols are proposed to solve the shortcomings of traditional routing protocols. ...
