• The hierarchical localization method classifies nodes into frame nodes and ordinary nodes. The frame nodes are localized by centralized algorithm first, and then the ordinary nodes are localized. This paper presents a distributed hierarchical localization method, in which the frame nodes' locations are computed by distributed algorithm. This method does not require a central node in the network, and its computational complexity is lower than the non-hierarchical distributed algorithm and the centralized hierarchical algorithm. Simulation results show that the proposed method could reach almost the same location accuracy as the previous methods.
