Congestion Control Algorithm Based on Cross-Layer Load-Aware in Wireless Mesh Network

LI Tao-shen,WEI Yan-xia,GE Zhi-hui(School of Computer,Electronics and Information,Guangxi University,Nanning 530004,China)  
To solve the gateway congestion control problem of wireless Mesh network(WMN),a new congestion control algorithm based on cross-layer load-aware in WMN(CCACL) is proposed based on the existing congestion control strategies.CCACL adaptively adjusts the sending rate of source nodes according to the local congestion information,and it simultaneously,appropriately adjusts the congestion threshold limit of the next hop nodes as well for emptying the buffer faster and to ease the network congestion.In order to ensure the reliability of data transmission,CCACL integrates an end-to-end selective acknowledgement mechanism based on the hop-by-hop reliability assurance mechanism.Simulation shows that CCACL can increase the network throughput,reduce end-to-end delay,and effectively solve the congestion problem in WMN.
