Design and Performance Analysis of TCP Enhanced Accelerator in IP Network

Abstract

This paper proposes a reliable LEACH protocol based on the packet loss rate measurement design based on the LEACH protocol. First, assume that the wireless link channel is unreliable, and there is a certain probability that data packets will be lost. In order to estimate the packet loss rate of the node, in each round of data transmission, the current statistics of the packet loss rate of the target node will be dynamically updated through an iterative formula. On this basis, a trust model for neighbor nodes is established. Under this condition, the packet loss rate of the selected head node is introduced and the distance factor is combined as the basis for determining the selection of the cluster head. In the end, the overall successful transmission rate of network data can be increased, and the additional energy consumed by nodes due to data packet retransmission can be reduced, so as to achieve the purpose of network energy saving and improving data transmission efficiency.
