Method for processing inertness of frequency-hopping FHSS wireless network facing to multi-interference circumstance application

Abstract

The invention relates to the computer communication technical filed, and particularly to an inertia processing method for a frequency hopping FHSS wireless network applied to the multi-interference environment. The inertia processing method comprises a user data interface, a data interface, a hardware drive, an Ad Hoc functional module and a radio frequency module; an ARM9 chip in a core circuit of the Ad Hoc functional module is connected with a radio frequency circuit through an SPI interface, so as to achieve the transmission and the control of data; a linkage road state is determined by adopting a network protocol algorithm on the basis of a DSDV route protocol, so as to increase the inertia avoiding time cycle; when interference exists, a route trial is carried out by firstly adopting a frequency hopping FHSS, and an avoiding time interval Tinert is arranged as a configuration parameter; when frequency-hopping communication can not be achieved due to a certain route failure, and a plurality of inertia cycles are kept, a new route update strategy is started. Compared with the prior art, the inertia processing method has the advantages that the frequency of updating a route is reduced, and the inertia processing method has stronger capacity of interference resistance.

[0005] When the Ad Hoc self-organizing wireless network is used in an environment with a lot of electromagnetic interference, due to the existence of electromagnetic interference, the link is more likely to be affected. In the case of external interference, the general Ad Hoc routing protocol generally adopts Start the routing algorithm to find a new routing method, which will cause the entire self-organizing network system to enter a low efficiency period, and, under normal circumstances, such as in coal mines, construction sites, enterprises and other environments with more electromagnetic interference, many The occurrence of electromagnetic interference has certain characteristics, especially the intermittent and temporary nature of the interference. In such an environment, the efficiency of using a general-purpose routing algorithm will be relatively low, and sometimes it will not be effective. For example, when restarting a new After the routing protocol has established a new route, the interference may have disappeared, so frequent startup of the routing algorithm will undoubtedly greatly reduce the transmission efficiency of the system
