Abstract

The invention discloses a wireless network routing method based on a directive antenna. The wireless network routing method based on the directive antenna comprises the following steps of: eliminating a path-diffused loop by introducing a node level configuration, and ensuring that a path request message is quickly diffused to a target node; planning an optimal path decision by the target node in a process of reverse feedback replied by the path so as to prevent directional delay caused by path request feedback of each link under the condition that a source node makes a decision; and timely and effectively establishing communication link through a communication azimuth angle with a next jumping node recorded by a middle node when the path requests a replay and backward feedback so as to reduce sweep delay introduced by the directional communication of the node. According to the invention, requirements of an on-demand communication service of the source node on QoS (Quality of Service) of the link are fully considered, and a level concept into the node in a process of establishing a route is introduced; and in addition, by a distributive processing method, a self-adaptive distributive QoS route is finally established by quick conditional forwarding of the middle node and an optimal decision of the target node.

Description

technical field [0001] The invention relates to a wireless network routing method, in particular to a directional antenna-based wireless network routing method, and belongs to the technical field of wireless communication. Background technique [0002] The application of directional antennas in wireless networks will greatly improve the confidentiality of wireless communication, especially in military communication networks, increase communication distance, improve network space utilization, and increase network capacity. , especially one of the hotspots in the field of military communication applications. However, it should be noted that the above-mentioned advantages brought by the introduction of directional antennas are at the cost of reduced overall network mobility, which will greatly reduce the diffusion efficiency of network information, such as routing link information, routing establishment and maintenance information As well as the diffusion of business-oriented ...
