The communication network includes fixed nodes connected to a router connected to at least one foreign network and mobile nodes connected to the fixed nodes. A second mobile node is selected from among mobile nodes connected to a fixed node whose available throughput is estimated in a first mobile node.

    摘要： A buffering apparatus and method for packet aggregation are provided. A buffer buffers packet data to be transmitted on a frame basis. An aggregator represents the positions of the buffered packet data in an Access Category (AC) bitmap and a Traffic Identifier (TID) bitmap according to an AC and a TID of the buffered packet data, and provides a bitmap indicating the positions of packet data to be aggregated according to an aggregation condition to an aggregation controller. The aggregation controller aggregates the packet data based on the bitmap received from the aggregator, constructs an aggregation Physical Service Data Unit (PSDU) with the aggregated packet data, and transmits the aggregation PSDU to a destination.

    摘要： Disclosed is a method for configuring a bitmap in a mobile communication system employing a block ACK scheme, which faithfully performs its intrinsic function of acknowledging a reception result, and yet can reduce transmission delay and the overall system load due to retransmission in the case where packet loss is relatively less important than transmission delay time, such as in the case of voice communication. To this end, a recipient compares a PER of a received packet signal with a threshold value. If the PER is higher than the threshold value, the recipient operates in the block ACK scheme, and if the PER is lower than the threshold value, the recipient determines a bitmap configuration scheme on the assumption that an erroneous frame has been successfully received. Also, using the determined bitmap configuration scheme, the recipient transmits a reception result for each received packet.
