초록정보

The packet data service is one of services supported in the third generation wireless network. This service is tolerable to a range of delays but fragile to packet losses. Buffer management scheme can provide quality-of-service (QoS) of packet data service by decreasing packet losses. Moreover shared buffer is more appropriate for packet data service because of the 'bursty' nature of packet traffic. In this paper, we propose a new buffer management scheme that has low packet dropping rate and guarantees fairness among connections. It is similar to the Drop-On-Demand (DoD) scheme, but uses more information of connections provided by the system. While the packet dropping criteria of the DoD scheme are the queue length of connections, the proposed scheme uses both the queue length and the channel bandwidth of connections. Through simulation, we compare the proposed scheme with the DoD scheme. The simulation result shows that packet dropping rate (PDR) is reduced by 20% with the proposed scheme. This means that the proposed scheme is highly efficient. Moreover the proposed scheme remarkably de-creases PDR of faster connections without high PDR increases of slower connections.
