Central devices may be present in the surrounding area of a peripheral device. Priorities of the central devices for supporting the peripheral device may be determined based on one or more factors associated with the central devices. The manner in which the central devices are used to support the peripheral device may be determined based on the priorities. The prioritized usage of central devices for the peripheral device may be dynamically updated. ## Claims ### Claim 1 A method comprising: comparing, by a computing device, a quantity of a plurality of central devices to a threshold quantity of central devices required to support a service usable to determine a location of a peripheral device;
