摘 要: 传统网络的容错系统未全面分析网络特征,处理多路径缠绕问题时,存在耗能高以及波动大等问题。因此,设计无线传感器网络不相交多路径路由容错缠绕系统,其采用基于HSV色彩空间分离的节点不相交多路径路由算法建立源节点到目标节点的不相交多路径。系统将色彩平面划分成A类型和B类型,并分别进行路径选择分析,实现不相交多路径路由的容错处理。系统通过动态时间间隔的链路RSSI检索方案检索动态节点,调整多路径缠绕,解决节点路径缠绕问题。实验结果说明,所设计系统可显著增强数据传输稳定性以及网络吞吐量,确保网络能耗最小。

Abstract: Since the network characteristics of the traditional fault?tolerant system havent been analyzed fully, which has the problems of high energy consumption and large fluctuation while dealing with the problem of multipath winding, a disjoint multipath routing fault?tolerant winging system for wireless sensor network was designed. The node disjoint multipath routing algorithm based on HSV color space separation is used to establish the disjoint multipath from the source node to the target node. The color plane is divided into A?type and B?type by means of the system, for which the path selection analysis is carried out respectively to realize the fault?tolerant treatment of the disjoint multipath routing. The link RSSI retrieval scheme of dynamic time interval is used to retrieve the dynamic nodes of the system. The multipath winding is adjusted to solve the problem of node path winding. The experimental results show that the designed system can enhance the data transmission stability and network throughput significantly, and ensure the minimal network energy consumption.

无线传感器网络受到恶劣环境、能量约束等因素的干扰,会出现节点损坏以及通信链路断裂的问题,导致数据传输效率大幅度降低[1]。因此,无线传感器网络的容错性能对增强网络性能具有重要作用。网络节点移动过程中会出现缠绕问题,导致网络通信路径断裂,数据传输效率大大降低[2]。而无线传感器网络容错缠绕系统可确保网络出现缠绕问题后,对传输数据进行恢复,增强网络稳定性。
