WSN Node Localization Algorithm Design Based on RSSI Technology

Constrained by extraneous factors and power consumption of nodes, the traditional localization algorithms have some disadvantages in localization process, such as low localization accuracy, large amount of computation, etc. For this reason, the WSN node localization system based on RSSI technology is proposed. This algorithm improves node localization accuracy by conducting iteration refinement to the solutions, through quantification of the measurement of target parameters and geometric approach computation. This method can effectively reduce the communication overhead among network nodes, save network power and extend the life cycle of the network. The experimental results show that this method can complete complex computation process with fewer parametric variables, thus strengthening the robustness and stability of the entire network.
