Improved three-edge localization algorithm based on coordinate correction |
| |
| Abstract: | Marine Wireless Sensor Networks (WSN) are of high dynamic of nodes, complex motion state of nodes, larger sheltered effect of communication, and serious attenuation of signals. In view of this, the three edge localization algorithm of traditional WSN is applied to marine environment, and an improved three edge localization algorithm based on coordinate correction is put forward. EXata platform is used to simulate the algorithm. Simulation results show that the proposed algorithm is of higher localization accuracy and better adaptability for dynamic marine environment, and can improve the efficiency of search and rescue. |
