| Abstract: | Aiming at the network characteristics of wireless Mesh networks（WMNs）,an LLECC congestion control strategy based on link load estimation is proposed,which estimates the tuning factor of RED algorithm by calculating the available link bandwidth and link loads. The parameters in RED algorithm are adjusted by tuning factor to realize dynamic wireless network congestion control. The realization process of LLECC algorithm and computing method of parameters are discussed in detail. Through the analysis and simulation,it is proved that the LLECC algorithm can increase the performance of the wireless Mesh networks. |
