Established in 1986, the Chinese journal of Control and Decision is sponsored by Northeastern University and under the administration of the Ministry of Education of China. The journal is published monthly with a total of 256 pages in A4 size, and is distributed at home and abroad. For more than 30 years, "Control and Decision" has adhered to its mission and purpose, and has committed to gathering and disseminating outstanding academic achievements, inspiring scientific and technological innovations, and advancing the development of China's academic disciplines. The journal has published a great number of high-standard, original, and outstanding research achievements, both in theory and in practical applications, in the field of control and decision-making. With a good academic reputation in both academia and industry, high academic influence, and excellent level of publications, "Control and Decision" has attained top rankings in both core impact factors and comprehensive evaluation indicators. The journal has received many prestigious awards including "Top 100 Outstanding Academic Journals of China", "China's Most Influential Academic Journals”, and so on, and has been included in key national and international databases. In November 2019, the journal was selected for the “China Science and Technology Journal Excellence Action Plan”, a national project jointly implemented by the China Association for Science and Technology, the Ministry of Finance, the Ministry of Education, the Ministry of Science and Technology, the General Administration of Press and Publication, the Chinese Academy of Sciences and the Chinese Academy of Engineering. This will be yet another great motivation for “Control and Decision” to contribute relentlessly to the construction of the Chinese science and technology journals system of open innovation, cooperation, and world-class.

A distributed algorithm based on supernodes is proposed to iteratively locate the large number of sensor nodes in wireless sensor networks. In terms of the overlapped decomposition of the entire network, two steps are involved at each iteration of the algorithm: one is the node localization method within each subgraph and the other is the local consensus among neighbor subgraphs. To be specific, the conjugate gradient method is employed to determine the position of nodes in subgraphs. Then, the position of each node will be adjusted by a neighboring consensus strategy. These two steps are repeated until the iterative termination condition is satisfied. Simulation results show that the proposed algorithm is an order of magnitude lower positioning error than the existing distributed algorithms and can efficiently locate nodes in large-size wireless sensor networks.
