Radio Link Admission Algorithms for Wireless Networks with Power Control and Active Link Quality Protection

In this paper we present a distributed power control scheme, which maintains the SIRs of operational (active) links above their required thresholds at all time (link quality protection), while new users are being admitted; furthermore, when new users cannot be successfully admitted, existing ones do not su er uctuations of their SIRs below their required thresholds values. We also present two admission/rejection control algorithms, which exercise voluntary drop-out of links inadmissible to the network, so as to reduce interference and possibly facilitate the admission of other links.
