Various applications of machines in Internet of Things require different bandwidths. Each machine may choose its RF interface in machine-to-machines or machine-to-base stations communications according to required bandwidth. We propose an optimal next-hop selection framework with a dynamic RF interface setting for sources with the same requested bandwidth. This framework enables machines to optimally select network devices with different RF equipment. In this way, the efficient use of RF network resources can be improved. The simulations show that the average data rate of sources improved between 11.1% to 117%, and the average unmatched source number improved between 1.9% and 5.3%.
