R2S: Radio Resource Sharing for Wireless Network Reliability in Internet of Things

摘要

Internet of Things is a system where people and things with unique identifiers are connected andable 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 servicecan be provided to nodes even in the event of a sudden network failure. To serve consistent qualityof service for nodes in any case, we propose a radio resource sharing (R2S) method which consistsof scheduling and power allocation using an optimization method. By evaluating performances withrespect to average cell capacity and outage probability in simulations, we show that the R2S algorithmcan solve a coverage hole problem efficiently in Internet of Things.
