目前，大多数无线传感器网络（WSNs）利用睡眠机制来节省能量，这引入了数据可用性的问题。为了解决这个问题，我们设计了DSSN，一个数据集同步协议的无线传感器网络与睡眠传感器通过命名数据网络（NDN）。DSSN将传感器分成多个组，每个组都有一个共享的数据集;通过每个组内的数据集同步，DSSN确保该组的最新数据集始终可以从其活动传感器访问。DSSN利用状态向量实现可靠的数据集同步，并利用NDN的兴趣聚合和数据缓存来优化能耗。我们评估DSSN通过广泛的模拟实验，我们的结果表明，DSSN确保数据可用性接近100%，在各种网络条件下，可以忽略不计的开销。
Currently, most Wireless Sensor Networks (WSNs) utilize sleeping mechanisms to conserve energy, which introduces the problem of data availability. To address this problem, we designed DSSN, a Dataset Synchronization protocol for WSN with Sleeping sensors over Named Data Networking (NDN). DSSN divides sensors into groups, each has a shared dataset; through dataset synchronization within each group, DSSN ensures that the group's latest dataset is always accessible from its active sensors. DSSN utilizes State Vector to enable reliable dataset synchronization, and utilizes NDN's Interest aggregation and Data caching to optimize energy consumption. We evaluated DSSN through extensive simulation experimentation, and our results show that DSSN ensures data availability close to 100% under various network conditions with negligible overhead.
