Abstract:: After a sludy of the classieal clustering algorithms such as ETBG, a clustering topology algorithmBased on Uneven Gradient in WSN was proposed. This algorithm not only uses analytical hierarchy Proeess todetermine the coeflieient of each faetor, but also improves cluster members choiee slrategy based on the idea oluneven gradient, thus the cluster heads closer to the base station can preserve some energy for the inter-clusterdata forwarding. Simulation experiments demonstrate that this algorithm provides an efficient solution to copewith the energy hole problem and prolongs entire network lifetime.
