OVERLAPPING PRIORITY CONTENTION WINDOWS FOR G3 POWER LINE COMMUNICATIONS NETWORKS

摘要

Embodiments of methods and systems for overlapping priority contention windows (707, 801) in G3-PLC networks are presented. In one embodiment, a Normal Priority Contention Window (NPCW) (801) is allowed to overlap with a High Priority Contention Window (HPCW) (707). The minimum contention window (801) for the normal priority frames (i.e., NPCW) is equal to or longer than the contention window (707) for high priority frames (i.e., HPCW). By making the NPCW (801) longer than the HPCW (707), the high priority frames will have a better chance than normal priority frames to get access to the channel on transmission reattempts.
