Abstract：In the large-scale high-speed mobile ad-hoc networks,the rapid movements of nodes make the network topology change frequently,so it needs to speed up the routing update,which leads to the continuous increase of the routing overhead and degrades the performance of networks.To solve this problem,this paper proposes the fast hazy optimized link state routing (FH-OLSR) protocol,which is based on OLSR,the introduction of hazy sighted technology and the fast routing technology.By monitoring the changes of node link state,the transmit frequency and range of handshake messages and topology control messages can be automatically adjusted.Meanwhile the link state routing computation can be integrated to effectively speed up the network topological convergence and reduce the routing overhead and improve the network performance.The experimental results in OPNET show that in large-scale network topological high-speed changes,compared with the OLSR protocal,FH-OLSR can reduce the routing overhead,end-to-end delay and the packet loss rate by 25％,50％,15％,respectiely.
