摘 要：A campus grid, a computational grid confined to a campus, requires temperature monitoring by huge number of sensors if it is to run without air-conditioning. To reduce the number of temperature sensors for the monitoring, a sensor location optimization method based on analysis of thermal behavior is proposed. The method eliminates sensors based on correlation between source heat and inlet temperature of PCs, The method enables to eliminate the sensors that are not sensitive to heat source, and results in sensor location optimization. Initial experiments in an actual campus grid show that such sensitivity does exist and clarify advantages of the method against simple optimization method based on just temperature.
