We analyze a multi-server queueing system with limited resources and signals. A customer requires a random value (RV) of the shared resources. Each customer generates a flow of signals triggering the resource reallocation process that make a customer release the occupied amount of resources and request a new RV of resources instead. Considering users are constantly moving within the signal coverage area we describe a model of a wireless network where resources have to be reallocated due to changes in the requirements. We assume that user session cannot be interrupted because of lack of the resources in the instant of the resource reallocation. © Springer International Publishing AG 2017.
