Transmission Control Method Using Hierarchical Clustering in Information-Centric Sensor Networks

Abstract

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.
