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

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.
