Fuzzy logic autonomous navigation method for WSN mobile nodes
Ding Ming-li · Systems engineering and electronics · 2009
A distributed fuzzy logic autonomous navigation method for wireless sensor network(WSN) mobile nodes is proposed.A smart mobile robot is designed as the mobile node of WSN,the coordinate space which is quantized by using RSSI value is used for describing robot's state and target position,and it can efficiently avoid the model error while RSSI is transformed into distance values.The navigation system is consists of some beacon nodes,and each of them is a distributed measurement and control unit.Then the fuzzy logic control centre collects the outputs from every beacon node and calculates the final outputs for the mobile robot based on data fusion.The experimental results confirm that the effectiveness of the navigation system.
