摘      要：In large-scale networks such as the Internet of Things(IoT),devices seek multihop communication for longdistance communications,which considerably impacts their power ***,this study proposes an energy harvesting-enabled,relay-based communication in multihop clustered IoT networks in a bid to conserve the battery power in multihop IoT ***,this study proposes an efficient,hierarchical clustering mechanism in which entire IoT devices are clustered into two types:the closest cluster(CC)and remote clusters(RCs).Additionally,Euclidean distance is employed for the CC and fuzzy c-means for the ***,for cluster head(CH)selection,this study models a fitness function based on two metrics,namely residual energy and distance(device-to-device distance and device-to-sink distance).After CH selection,the entire clustered network is partitioned into several layers,after which a relay selection mechanism is *** every CH of the upper layer,we assign a few lower-layer CHs to function as *** relay selection mechanism is applied only for the devices in the RCs,while for devices in the CC,the CH functions as a ***,several simulation experiments are conducted to validate the proposed method’s *** results show the method’s superiority in terms of energy efficiency and optimal number of relays in comparison with the state-of-the-art methods.
