A New Dynamic Optimal Relay Selection and RF interfaces Setting Algorithm (DORSA) in M2M for IoT Applications
share
Machine-to-Machine (M2M) communication is one of the main communications in the Internet of Things (IoT). How to send data in these high-density communications using relay selection can help better performance of this type of communications in various applications. In addition, the possibility of simultaneous use of different Radio Frequency (RF) interfaces helps to make better use of the network radio frequencies. Therefore, in this work, we try to further use of machine communication equipment and improve the average data rate of networks in different applications such as the Internet of Things, which have different bandwidth requirements, by providing an optimization algorithm for relay selection as well as the simultaneous and dynamic multiple M2M RF interfaces setting that called Dynamic Optimal Relay Selection and RF interfaces Setting Algorithm (DORSA). The simulation results show that the average DORSA_W-B-Z data rate is improved by 0.8 to 10 transmission as well as relay selection algorithms with static RF interface setting.
