Methods and apparatus are provided for automatically and autonomously
forming a wireless personal area network (WPAN) from an array of
intercommunicating personal area network (PAN) devices. The devices
comprise first communicators associated with primary functions of the
devices and second communicators coupled to the first communicators for
determining a subset of the devices meeting predetermined association
criteria, from which subset the first communicators form the WPAN. In a
preferred embodiment, the second communicators include range measuring
transceivers and processors coupled to the transceivers that cooperate to
determine range and relative motion of elements within communication
range of the first communicators for comparison to range and relative
motion association criteria stored in one or more of the devices. Memory
is desirably included for storing the association criteria. The subset of
devices automatically elects a master device that communicates with the
other devices of the subset to form the WPAN.
