Abstract
This article presents a novel multicast retransmission scheme for wireless communication network in the ubiquitous electric internet of things. Firstly, the advantages and disadvantages of two retransmission schema, the centralized and distributed, are analyzed. Then, a new method is consequently proposed based on retransmission mode preselection. Instead of the approach of the UEs in the centralized scheme, the proposed method's signaling cost is significantly reduced through reporting ACK/NACK and link quality by the cluster head UE. The proposed method can avoid resource waste of the base station to reserve wireless resource for retransmission. In addition, the cluster head can exploit the multicast gain and multichannel diversity gain jointly. Finally, the computer simulations verify the effectiveness of both the cost and the efficiency of the proposed method.
