Abstract: In order to solve the problems of poor information fusion effect and prolong information fusion in current methods，a multi-channel information fusion method for wireless networks based on grid system is proposed． The support degree of wireless network sensor is calculated by using the correlation function in the fuzzy theory． The knowledge element model is used to obtain the fusion set of information，and it is taken as an information unit to provide the basis for the multi-channel information fusion of wireless network． Based on the entropy weight method，the European distance measurement between the multi-channel information of wireless network is introduced． The global and local fusion weights of information are obtained by using the concept of distance entropy，and the global and local fusion results of channel information are calculated by using linear weighting method． Finally， the fusion of multi-channel information in wireless network is realized． The experimental results show that the proposed method is effective and feasible for multi-channel information fusion in wireless networks with short time delay and good real-time performance．
