Robot routing using clustering-based parallel genetic algorithm with migration

Ko-Ming Chiu, Jing-Sin Liu
2011 2011 IEEE Workshop On Merging Fields Of Computational Intelligence And Sensor Technology  
This study focuses on data gathering by a mobile robot in a WSN, also referred to as a robot routing problem. It is formulated as a Traveling Salesman Problem with Neighborhoods (TSPN).  ...  The first phase of the method consists of a Euclidean-distance based clustering algorithm that assigns the nodes to clusters, and the second phase routes these clusters by planning the data collection  ...  Performance of approximation algorithm [16] is close to clustering for medium-size network.  ...
