Title:
METHOD FOR SELECTING OPTIMAL MULTI-HOP PATH FOR WIRELESS SENSOR
Document Type and Number:
WIPO Patent Application WO/2021/164791
Kind Code:
A1
Abstract:
The present invention relates to the technical field of wireless sensor networks, and specifically relates to a method for selecting an optimal multi-hop path for a wireless sensor network. The method comprises: according to the energy of an initial node and the consumption of a transmission node, establishing an energy efficiency calculation model to calculate the remaining energy; according to the neighbor node information and the position information of the next-hop node, establishing a data aggregation model and calculating the distances between cluster heads and member nodes; according to the node density, determining m initial cluster centers; on the basis of the m initial cluster centers, using a membership function of an improved fuzzy if-then rule to correspondingly output m optimal cluster heads; sending the information to the corresponding optimal cluster heads, and transmitting the data to a destination by means of multiple forwarding between optimal cluster heads; according to the number of iterations and the transmission success rate between clusters, discarding or merging invalid paths to complete path search; by means of evaluating the path quality, finding the optimal path from the found paths by competing, comparing, and solving for the optimal path. The present invention can effectively reduce and balance network energy consumption and extend network service life.
