Channel access algorithms with active link protection for wireless communication networks with power control

A distributed power-control algorithm with active link protection (DPC/ALP) is studied in this paper. It maintains the quality of service of operation al (active) Links above given thresholds at all times (link quality protect ion), As network congestion builds up, established links sustain their qual ity, while incoming ones may be blocked and rejected. A suite of admission control algorithms, based on the DPC/ALP one, is also studied. They are dis tributed/autonomous and operate using local interference measurements, A primarily networking approach to power control is taken here, based on th e concept of active link protection, which naturally supports the implement ation of admission control. Extensive simulation experiments are used to ex plore the network dynamics and investigate basic operational effects/tradeo ffs related to system performance.
