摘　　要：传统无线传感器网络(wireless sensor network,WSN)基于IP网络,难以发挥出智能配电网中多种接入网络的性能;同时,在气象灾害或巡检无人机等动态场景下难以获取节点IP地址,无法及时有效完成数据收集任务。命名数据网络(named data networking,NDN)的出现,为解决上述问题提供了可能。NDN以数据需求为驱动,符合WSN只关注数据收集任务本身的初衷。结合NDN新型网络架构对于底层网络协议透明的优势,提出了一种智能配电网中感知数据收集协议——T-ND-WSN。仿真实验表明,该协议结合网内缓存机制,在满足智能配电网数据通信时延上确界前提下,在数据传输服务质量上具有明显优势。The traditional wireless sensor network(WSN)is based on IP protocol,and it is difficult to exert the performance of vari⁃ous access networks in s SDGs.Meanwhile,it is also difficult to obtain node IP addresses in dynamic scenarios such as meteorologi⁃cal disasters or inspection drones,and data collection tasks cannot be completed in a timely and effective manner.The emergence of named data networking(NDN)provides a possibility to solve the above problems.The NDN is driven by data requirements,which is in line with the original intention of WSN data collection tasks.The NDN's network architecture is transparent to the underlying network protocol,in this paper,combined with this advantage of NDN,a sensing data collection protocol for SDGs called T-NDWSN is proposed.Combined with the caching mechanism within network,T-ND-WSN can satisfy the time delay supremum of data communication in SDGs and has obvious advantages in QoS of data communication.
