Summary We consider and analyze a single‐server multiqueue polling model with inner arrivals. Customers arriving at the queue before polling instant could receive service in the current polling round; furthermore, each one could be retried (turns into an inner arrival) a given number of times with a specified probability. Such polling model can be used to study the performance of certain scheduling data transmission in the Internet of Things (IoT) and the relationship between data retransmission and delay. We obtain the closed‐form expression for the generating function of the amount of customers, which are presented at polling instants. Then, it is used to derive the precise closed‐form formula of mean queue length and mean waiting time in symmetric system.
