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.
