Abstract

Cellular Internet of Things (cIoT), which will create a huge network of billions or trillions of Things communicating with one another, are facing many technical and application challenges. In particular, in this paper, we have proposed a mechanism based on D2D multicast group communication. The goal of us is to enhance the coverage ability of the cellular network system which is used in IoT. Firstly, we propose a D2D clustering algorithm with the consideration of energy consumption and the outage of the system. Secondly, we want to improve the throughput of the whole system. We decomposed this optimization problem into two sub problems: power control and channel assignment. Referring to the Genetic Algorithm, we get the optimal transmit power of the whole devices. Then, we use the Greedy Algorithm to obtain the perfect channel allocation. Finally, the simulation results demonstrated the efficiency of the communication mechanism proposed by us.
