| 摘 要： | 针对附加QoS需求的无线传感器网络，给出一种满足生命期和干扰服务要求的无线传感器网络无标度容错拓扑控制算法（scale-free fault-tolerance topology supporting quality of service，简称QoS-SFT）.通过分析无标度拓扑的度分布属性与其生命期和干扰性能的关联关系，量化出生命期和干扰联合优化的无标度拓扑度分布表达式，进而以无标度拓扑的度分布表达式为设计目标，采用偏好依附规则实现QoS-SFT算法设计，形成能够满足生命期和干扰联合优化要求的容错拓扑.理论分析和仿真结果表明，QoS-SFT算法不仅能够保证无标度拓扑的强容错性，还有效提升了无标度拓扑的生命期和干扰性能.

| Abstract: | To address the additional service quality requirements of wireless sensor networks, a scale-free fault-tolerance topology control algorithm is proposed. The algorithm constructs the scale-free topology that satisfies the additional optimum required for the lifecycle and interference services. First, the coupling relationship between the topological degree distribution and its performance on both lifecycle and interference is analyzed. Then, the degree distribution with the optimal requirement of lifecycle and interference services is determined. Furthermore, the scale-free topology control algorithm based on the preference attachment rule is proposed to construct the scale-free topology with optimal degree distribution. Finally, the scale-free topology fulfilling the optimum of both lifecycle and interference is also obtained. The theoretical analysis and simulation results show that the presented scale-free topology control algorithm can assure the strong fault-tolerance, and improve the lifecycle and interference services simultaneously. |
