摘要: 遵循控制转发分离思想,软件定义无线传感器网络(Wireless Sensor Network,WSN)数据转发采用基于流的实现方式.因此,软件定义WSN规则更新过程中节点行为可能违背网络属性一致性.针对此,提出每包前向一致性概念,并证明其可保持所有网络属性的更新一致性.在此基础上,通过引入缓存节点与缓存规则简化规则依赖关系,提出一种规则前向一致更新算法,在满足每包前向一致性的同时,支持规则快速并行更新.实验结果表明,算法在规则开销、更新时间和通信开销等关键性能指标上具有较为明显的优势.

Abstract: Following the idea of separation of control and forwarding,the data forwarding of software-defined WSN (Wireless Sensor Network) is implemented in a flow-based manner.Therefore,nodes behavior during rule updating in software-defined WSN may violate network attribute consistency.Therefore,this paper proposes the concept of per-package forwarding consistency and proves that it can maintain the update consistency of all attributes.On this basis,a rule forwarding consistent update algorithm is proposed by introducing cache nodes and rules to simplify dependencies.The algorithm supports fast parallel updates while satisfying the per-package forwarding consistency.The experimental results show that the algorithm has obvious advantages in the rule cost,update time and communication overhead.

Key words: wireless sensor network, software-defined networking, Internet of Things (IoT), software-defined wireless sensor network, network security, rule update, per-package forwarding consistency
