    摘要: The present invention relates to a local retransmission scheme, which uses Transport Control Protocol (TCP) in an unreliable network. It provides reliable transmission for out-of-order TCP data packet in an unreliable link. It recovers non-congestion loss packets. It avoids incorrect adjustment of window size in TCP source end. It applies TCP local retransmission scheme, which checks together a link layer transfer sequence and a TCP source delivery sequence. With inserting timestamp of local sequence number, which is in TCP data packet and TCP acknowledgement packet, together with acknowledgement number AN, it is defined whether a data packet is lost and retransmitted. Then, with explicit retransmission ERN feedback, a TCP source false action is avoided. Therefore TCP performance of a wireless network is greatly improved.

In the example methods and system, data packets may be routed to and/or between any node within a Mobile Ad-Hoc Network (MANET), such as a network running Ad-hoc On-demand Distance Vector (AODV) protocol, and an external connection or device (e.g., an Internet entity) if at least one node within the MANET includes a connection to the external connection or device. Accordingly, a single “connected” MANET node may share its external connections with non-connected nodes.

    摘要: A subchannel scheduling method in a multi-user MIMO-OFDM environment modifies proportional fairness scheduling specifications and maximizes a system throughput under conditions that a minimum data transmission rate required by a multimedia user be ensured. In a method for allocating subchannels in a wireless network, plural users are subscribed in the wireless network, a base station has NT transmission antennas, a user i has NR reception antennas, a network capacity determined by the NT transmission antennas and K subcarrier groups is divided into K transmission subchannel groups, and a network bandwidth determined by the NT transmission antennas is divided into the K subchannel groups. The base station sequentially allocates channels to the users on the basis of a proportional value of a data transmission rate supported to each user and an average throughput of each user in a predetermined time and a service quality required by each user.
