摘要

针对具有传输控制协议（TCP）传输机制的无线传感器网络（WSNs）节点拥塞问题

在传输层的基础上结合物理层的信噪比（SNR）参数来估计信道状况

不断调整传输模型

实现跨层控制。此跨层方法改变了以往的单层拥塞控制方法

充分利用了WSNs层与层的协作关系

并用基于自适应趋近律的离散滑模控制结构模型作为控制器

过程简单且易于实现。仿真结果表明:该跨层拥塞控制方法具有响应速度快、延迟小、鲁棒性好等特点。

Abstract

Aiming at wireless sensor networks（ WSNs） node congestion problem of TCP transmission mechanism

on the basis of transmission layer

combine with SNR parameter of physical layer to estimate channel condition

and constantly adjust transmission model

implement cross-layer control. This cross-layer method makes full use collaboration relationship between layers of WSNs which changes the previous single layer congestion control method

use discrete sliding mode control structure model control based on self adaptive reaching-law as controller

which is simple and easy to implement. Simulation results show that the cross-layer congestion control method has characteristics of fast response speed

small delay

good robustness.
