On Transport Layer Retransmission Timeout in Ad Hoc/Manet Networks

Автори

This article describes a key aspect of providing the reliability of the network transport layer TCP/IP based networks, such as a retransmission timeout. We are improving the efficiency of the transport mechanisms by adapting the retransmission timeouts of the transport protocol to the conditions of operation of self-organizing radio networks. The basis for the proposed new method for determining the retransmission timeout of packets is to calculate the timeout for each route individually, rather than the cumulative timeout packet-receipts. This allows for a self-organizing networks to calculate such a number of timeouts, how many routes found up to the final destination. It is proved that such an approach can significantly reduce the waiting time in the case of packet loss and retransmit, and thus increase the overall throughput of the transport connection.
