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
