Embodiment Construction
[0024] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:
[0025] Aiming at the deficiencies of the prior art, the present invention comprehensively considers the position distribution of nodes and the impact of residual energy on the entire network life cycle when selecting cluster head nodes, and uses a fuzzy algorithm to fuse the position information and residual energy information of nodes into Quantified priority parameters, and then achieve more reasonable cluster head node selection and cluster division, and finally achieve the purpose of extending the life cycle of wireless sensor networks.
[0026] Fuzzy rules embody the characteristics of the human brain to recognize and judge things, and change digital and precise judgments into subordinate and fuzzy judgments. It fuzzifies the so-called judgment criteria, which can be used to solve similar fusion problems of many different types of parameters. In t...
