The invention provides a sensor network coverage hole detection method combining with energy efficiency. The sensor network coverage hole detection method combining with the energy efficiency includes: calculating residual energy of sensor nodes in a sensor network after the sensor network works for one period; judging whether sensor nodes become invalid because of energy depletion according to the residual energy: on yes judgment, calculating detection probability of the sensor network, and executing a step four; on no judgment, returning to the step two; judging whether coverage holes occur according to the detection probability: on yes judgment, calculating positions of the coverage holes, and executing a step five; on no judgment, returning to the step two; screening current effective sensor nodes combining with the energy efficiency, and deleting sensor nodes which cannot meet energy efficiency requirements; and calculating the positions of the sensor network coverage holes for the residual nodes which can meet the energy efficiency requirements. The sensor network coverage hole detection method combining with the energy efficiency guarantees that energy waste of the sensor network is small, prolongs service life of repaired network, reduces network repair cost, and improves guiding significance of hole detection results to actual repair.
