基于RED的无线传感器网络的拥塞控制

拥塞控制问题是影响无线传感器网络性能的一个重要因素。针对无线传感器网络中的拥塞控制问题,提出了一种基于RED的拥塞避免策略。RED算法目前比较常用于路由器队列管理中,以实现对缓存空间队列长度的管理。将其引入到无线传感器网络中,采用拥塞度门限值作为拥塞调节的依据,以matlab软件作为仿真工具,通过建立简单网络拓扑结构进行模拟实验,综合比对各个实验参数下的不同实验结果,从而得到适当参数值下,较好的无线传感器网络传输性能。

Congestion Control Strategy Based on RED Algorithm in Wireless Sensor Network

Congestion control problem is an important factor which impacts the wireless sensor network performance.Aiming at the congestion control problem in wireless sensor network,this paper put forward a congestion avoidance strategy based on RED algorithm.The RED algorithm now is usually used in routers to realize the management of the cache queue.This paper introduced it into the wireless sensor network,and adjusted the congestion on the basis of congestion degree threshold.Then the simulated experiments were carried out through establishing simple simulated network topology structure with Matlab.Different results in different experimental parameters were comprehensively compared and good transmission performance can be obtained in the proper parameter values,under the simple wireless sensor network.
