Matching algorithm is a key technology in content-based publish/subscribe system. Aiming at the lack of information sharing ability in dynamic wireless networks, an information distribution system model based on content-based publish/subscribe technology is established. Then, according to the subjectivity and fuzziness of users’ information requirements, using the logical coverage relationship between subscription constraints, an efficient fuzzy matching algorithm for battlefield information distribution and sharing is designed. Finally, the time and space efficiency of the algorithm are analyzed by experiments. Experimental results show that the algorithm is reasonable and efficient.
