英文摘要：

The status of monitored environment can be observed with wireless sensor network effectively. A building energy perform- ance monitoring process is implemented with sweep coverage model of wireless sensor network in this paper. To reduce costs on con- struction and maintenance for data acquisition system implemented with technologies of sweep coverage of wireless sensor network and to reduce the complexity of that data acquisition system, the minimal number problem of mobile node in sweep coverage is represen- ted as multiple traveling salesmen problem and a fast algorithm for the solution of that problem is presented. The fast algorithm is im- plemented with genetic algorithm in experiment for the performance of the new algorithm and experimental result show that the new fast algorithm for the solution of minimal number of mobile node in sweep coverage of wireless sensor network can search the minimal number of mobile node in sweep coverage effectively and the new algorithm implemented with genetic algorithm can find the upper boundary of the desired minimal number quickly.
