In order to solve the problem that the scale-free fault-tolerant topology with fixed power-law exponent is not universal, based on the node batch arrival rule in according with Poisson model and node attraction rule, a scale-free fault-tolerant topology algorithm with adjustable power-law and steady links ( named APSL) is proposed. Firstly, the criterion of connecting links is built according to receive signal strength indication, which avoids effectively the instable links. Secondly, a scale-free fault-tolerant topology with the power-law exponent in the range ( 1,+∞) is built through adjusting the topology parameters. The experimental results show that APSL algorithm can fit the variety requirements of fault-tolerance and raise the stability of links.%针对固定幂律WSNs无标度容错拓扑不具普适应的问题,采用节点批量到达的Poisson网络规模以及节点吸引度规则,提出幂律可调的WSNs无标度容错拓扑算法APSL. 该算法利用接收信号强度值建立通信链路,避免了网络中的不稳定链路,并通过调节拓扑参数,构建出了幂律指数在( 1,+∞)的无标度容错拓扑. 实验结果表明,APSL算法能够提升网络链路的稳定性,同时还能够满足网络多样化容错需求.
