在本文中，我们主要研究无线传感器网络环境中，移动汇聚节点以特定的时空方式遍历感知场，汇聚分布在传感器节点上的具有不同截止期约束的各种环境数据。针对这种情况，我们提出了一种能量高效的数据聚合方法，在保证预定的截止时间的同时，减少了多跳通信中的中间传输。该方法的基本方法是将观测到的数据临时收集(或缓冲)到移动汇点移动路径周围的几个传感器节点中，以便在下一次访问时满足它们的最后期限。然后，当移动汇聚节点访问缓存节点时，将缓存的数据传输到移动汇聚节点。我们还提出了一种移动汇聚发起的低成本主动路由协议(MIPR-LC)，该协议能够高效地构建到每个传感器节点上的缓冲节点的路由。此外，我们还对所提出的聚合方法和路由协议进行了仿真，以验证其有效性。实验结果表明，与简单的路由协议相比，MIPR-LC方法可以降低高达23%的能耗。此外，移动汇聚节点可以在截止期内收集几乎所有的观测数据。
In this paper, we focus on monitoring environments with wireless sensor networks in which mobile sink nodes traverse sensing fields in a specific spatialtemporal manner and aggregate various types of environmental data with different deadline constraints distributed over sensor nodes. For such environments, we propose an energy-efficient data aggregation method that reduces intermediate transmission in multi-hop communication while guaranteeing predetermined deadlines. The basic approach of the proposed method is to temporarily gather (or buffer) the observed data into several sensor nodes around the moving path of the mobile sink that would meet their deadlines at the next visit. Then, the buffered data is transferred to the mobile sink node when it visits the buffering nodes. We also propose a mobile sink-initiated proactive routing protocol with low cost (MIPR-LC) that efficiently constructs routes to the buffering nodes on each sensor node. Moreover, we simulate the proposed aggregation method and routing protocol to show their effectiveness. Our results confirm that the MIPR-LC method can reduce energy consumption by up to 23% when compared with a simple routing protocol. In addition, the mobile sink nodes can gather almost all of the observed data within the deadline.
