Method and device for optimizing OLSR protocol through multiple parameters

Abstract

The present invention discloses a method for optimizing an OLSR protocol through multiple parameters, comprising: sampling a link signal-to-noise ratio and a link transmission rate according to a predetermined cycle; according to a range corresponding to the link signal-to-noise ratio obtained by sampling, correcting the link transmission rate to obtain a final link transmission rate; according to the final link transmission rate, acquiring a link overhead; according to the link overhead and a packet loss rate, calculating to obtain a total link overhead; and calculating to obtain routes of the entire network using the Dijkstra's Algorithm according to the total link overhead. The method can meet the requirements of timeliness, accuracy and effectiveness of link overheads in multi-point networking, and can accurately reflect the current most-true link condition. The present invention furthermore discloses a device for optimizing an OLSR protocol through multiple parameters.

Description

technical field [0001] The invention relates to the field of route calculation, in particular to a method and device for multi-parameter optimization OLSR protocol. Background technique [0002] The traditional OLSR protocol uses small HELLO packets to count the packet loss rate and measure the link overhead. Therefore, there are mainly two problems in the application of actual data service forwarding: on the one hand, the routing calculation lags, and on the other hand, frequent switching near the critical point. These two aspects lead to intermittent gray screens or freezes in the video in the wireless video transmission application field, which affects the stability of video transmission. Especially in the application scenarios of mobile video data collection and transmission. At the same time, using a single signal-to-noise ratio or transmission rate to measure link overhead cannot fully, real-time, and accurately reflect the current most real link situation in ad hoc ...
