	abstract = {This paper proposes a retrial queueing model with the finite n
		umber of sources to evaluate the performance of spectrum renting in mobile cellular networks. The model incorporates
		necessary ingredients such as the finite number of subscribe
		rs, their impatience and a queue for the outbound service. To consider the specific feat ure of spectrum renting and
		the current mobile cellular technology, a variable number of servers that are switched on and off in groups is introduced.
		We present a novel way to take into account the renting fee, which can be used to fine-tune the operation of the spectrum renting procedure. Numerical results show that it is still profitable to initiate a spectrum renting request at high loads, even if no discount is offered by the frequency bands’ owners.},
