HOP-BY-HOP FRAME AGGREGATION FOR VOIP ON MULTI-HOP WIRELESS NETWORKS

摘要

A hop-by-hop frame aggregation method of a VoIP(Voice over Internet Protocol) in a multi-hop wireless network environment is provided to aggregate all frames transmitted to multiple hops without an additional burden through frame aggregation and pseudo-broadcast technologies in the network environment, thereby increasing a frame aggregation ratio as remarkably expanding the number of VoIP calls. If frames transmitted to multiple hops enter a queue for preparing transmission, the frames are aggregated so that the aggregated frames are transmitted, regardless of destination hops of each frame. Each receiver receives the aggregated frames through a promiscuous mode even though the receivers are not the destination hops, and processes the frames essential for the receivers, then sends ACK(Acknowledgement) signals to terminals which send the aggregated frames.
