In this paper, the authors propose a data gathering scheme for large scaled wireless sensor networks using multiple Mobile Data Collectors (MDCs) and the Spatial Division Multiple Access (SDMA) technique. They focus on minimizing the data gathering time by employing the SDMA technique, and minimizing the length of touring paths of MDCs by employing Voronoi diagrams. The proposed scheme facilitates all deployed sensors to experience uniform energy depletion by avoiding long-distance transmissions to the base station. This, in turns, helps to prolong the lifetime of the network, and the network remains connected for longer period of time and increases the robustness.
