ABSTRACT:
Applicants' Contention-Resolution System for a Command-Response Data Network uses a base unit (base) that detects the occurrence of collisions for the entire network and controls the maximum length of time allowed for the multiple remote units (remotes) in the network before re-trying to send responses to the base. The base either expands or contracts this maximum time delay as needed to accommodate the number of the possible network remotes, depending on the detected collision rate and the overall utilization of the network until the base determines that there are no remotes to be registered or all of the available network slots are filled, whichever occurs first.
