为ICN（信息中心网络）实现多种M2M服务的传感器网络的应用正引起关注。到目前为止，已经提出了一种使用聚类来提高数据收集效率的方法。在该方法中，通过只使用簇头构建路由和缓存数据来减少簇成员的负载。然而，假设簇头中的缓存容量没有限制。在本文中，我们考虑有限的缓存容量的情况下，提出了一种传输控制方法与层次聚类。在所提出的方法中，上层簇由多个下层簇的簇头组成。此外，在低层簇中，根据簇头和簇成员之间的距离来控制发送功率。从性能评估的结果，所提出的方法被发现是优于传统的方法在功耗方面的上级。
The application of sensor networks that realize multiple M2M services for ICN (information-centric networking) is drawing attention. Thus far, a method of improving the efficiency of data collection using clusters has been proposed. In this method, the load of the cluster members is reduced by constructing routes and caching data only with cluster heads. However, it is assumed that there is no limit of caching capacity in the cluster head. In this paper, we consider the case of limited caching capacity and propose a transmission control method with hierarchical clustering. In the proposed method, an upper layer cluster is formed with multiple cluster heads of lower layer clusters. Also, in the lower layer cluster, transmission power is controlled according to the distance between the cluster head and cluster members. From the results of performance evaluation, the proposed method is found to be superior to the conventional method in terms of power consumption.
