| Abstract: | This paper analyzes the range-free localization Algorithm APIT and API2T,points out the drawback of low accuracy and poor coverage.Wireless Sensor Network(WSN) localization algorithm based on grid scanning,called API3T,is proposed.In-To-Out error and Out-To-In error are reduced by redefining the neighbor nodes and it improves the strategy of the grid-scanning.Simulation experimental results show that the algorithm increases the localization accuracy and coverage. |
| Keywords: | Wireless Sensor Network(WSN) localization algorithm wireless propagation model grid scanning localization error |
