Fast Local Semi Definite Programming-based Localization for Large Wireless Sensor Networks

Recently, Wireless Sensor Networks (WSNs) are deployed inevitably in various technologies. By increasing the demand of deploying WSNs, some ambiguous parts of them should be cleared enough. One the bottlenecks of WSNs, is the localization of each node in WSN. In special applications, the location of sensors is mandatory. In this paper, the speed of localization is taken into account and a fast algorithm is developed to localize the sensors, accurately in a large WSN. Local semi definite programming (LSDP) is used to localize each sensor. The simulation results, has shown tremendous efficiency, from speed point of view.
