Internet of Things is a system where people and things with unique identifiers are connected and able to interact with each other over a network without external intervention. To connect things anytime, network reliability is one of the main requirements for the Internet of Things, in which continuous service can be provided to nodes even in the event of a sudden network failure. To serve consistent quality of service for nodes in any case, we propose a radio resource sharing (R2S) method which consists of scheduling and power allocation using an optimization method. By evaluating performances with respect to average cell capacity and outage probability in simulations, we show that the R2S algorithm can solve a coverage hole problem efficiently in Internet of Things.
