The invention provides a down-hole node energy-saving method based on hotspot areas, and belongs to energy-saving methods for a down-hole wireless sensor network. The down-hole node energy-saving method based on the hotspot areas includes: statistics of the down-hole hotspot areas is conducted, the hotspot areas in a period are determined, the statistics of the conversion between the hotspot areas is conducted, the transition probability of the hotspot areas is calculated by the adoption of a Markov process, and the control of the opening of the hotspot area nodes and the closing of non-hotspot area nodes is realized via the energy-saving method. Non-hotspot areas are areas in which a few miners are distributed at present or even without any personnel, multimedia sensor nodes of the hotspot areas need to be mainly monitored, nodes of the non-hotspot areas can be partly closed on the premise of keeping connectivity, the energy of the nodes is wasted by the monitoring of the down-hole non-hotspot ...
