Exploration time reduction and sustainability enhancement of cooperative clustered multiple robot sensor networks

A robot sensor network (RSN) is defined as a network of sensor-equipped robots and sensor nodes (that are deployed by the robots) that wirelessly communicate for remote-control, mission-cooperation, and to report sensed information to the control and reporting center (CRC). RSNs use real-time video communication support (in addition to various sensor data communication) for mission-cooperation and remote-control of its multi-robots. In this article, the hybrid data-type clustering (HDC) and subnet-divided HDC (SHDC) algorithms are proposed to maximize the RSN lifetime and enable more efficient multi-robot mission-cooperation.
