Abstract

The invention discloses a method for optimizing the real-time performance and reliability of a wireless sensor network of an intelligent power distribution network. The method includes constructing a fuzzy cognitive map model according to the major factors affecting the data transmission performance index of the wireless sensor network of the intelligent power distribution network, reasoning with the fuzzy cognitive map method according to the change of the network environment, improving the data transmission reliability of the wireless sensor network of the intelligent power distribution network by changing the dynamic decisive route path and adjusting the control variables of network parameters, and reducing the time delay of the network. A wireless sensor network data communication method of the intelligent power distribution network based on fuzzy cognitive map theory is disclosed. The data communication reliability and real-time performance of the wireless sensor network of the intelligent power distribution network are improved by dynamically adjusting transmission power, transmission rate and back-off strategy and changing route strategy, and data loss due to data transmission fault is effectively prevented. The technical foundation is provided to prevent power grid accidents due to incapability of reliably transmitting data on a real-time basis.
