摘　　要：针对WMSN中的空洞问题,使用两步前向区域进行空洞的预测,并使用投影距离代替贪婪算法进行选路,提出了TFAP(Two steps Forward Area Prediction)算法。仿真结果表明,TFAP算法改善了Qo S延迟和网络性能(两步前向区域空洞预测有效进行空洞优化,投影距离也能优化网络性能)。The problem of holes in the WMSNs have appeared in the perimeters,two steps forward area has been used to predict holes,and projector distance has been used instead of greedy algorithm. Two steps Forward Area Prediction（ TFAP） has been present. The simulation results show that TFAP algorithm has improved quality of service and network performance. Two steps forward area prediction has optimized holes effectively and projector distance can also optimize network performance.
