摘　　要：提出以先验效率(AE)为标准,对Grow算法中基本圈生成的中间p圈组,选择前N个先验效率最高的p圈继续扩张。仿真结果表明,在COST239网络中,p圈整体性能随参数N取值不同而不同,N=2时性能最佳,p圈数减少一半以上,整体先验效率增加,资源利用率提高。This paper chose a prior efficiency as the standard, for the group of intermediate p-cycles generated by each primary cycle in the Grow algorithm, the top N intermediate p-cycles which had the highest prior effi- ciencies were chosen to continue to expand.the simulatign results show that, in the COST239 network, the different parameter N will lead to different whole performance of p-cycles, when N=2, the algorithm gets the best performance, the number of p-cycles reduces more than half, the whole prior efficiency of p-cycles in- creases, the resource utilization improves.
