Proposed various positioning algorithms and application of the results of representative

Category summarizes the various localization algorithms proposed in recent years and representative application of the results, and focus on analyzing the advantages and disadvantages of each method. With the development of wireless sensor networks, and it is in people's lives and production application, the previous location  circuit breakers  is no longer able to meet the needs of production and life, people need higher  electri cenergy meter  accuracy; and previous localization algorithms are mostly static , the node's mobile positioning is more and more demand.  of low node positioning accuracy in distance-based localization algorithm based on RSSI, BP neural network algorithm to improve the positioning accuracy of the RSSI.
