Wireless mesh network is considered as one of the most valuable networking technologies in wireless multi-hop networks,which has made great contributions to the Internet of things,emergency communication,military applications and other fields.With the increasing application scenarios of wireless mesh networks,the routing protocol of wireless mesh networks has been paid more and more attention.At present,AODV protocol is widely used in wireless mesh networks.Therefore,this paper combines the advantages of heuristic algorithm based on AODV protocol and makes further research and improvement.The relevant research is as follows:In the process of heuristic algorithm research,this article in view of the existing heuristic algorithm is slow convergence speed,convergence in the process of the application of the adaptive ability is poor,the genetic and ant colony algorithm based on the two fusion,through the pheromone initialization,the improvement to the search strategy and pheromone update rules,this paper proposes a heuristic algorithm based on genetic ant colony fusion GA-AC algorithm,The experimental results show that the convergence efficiency and convergence speed of GA-AC algorithm are significantly improved,which provides a theoretical and application basis for the improvement of wireless mesh network routing protocol in the following.Aiming at the problems of AODV and A-AODV routing protocols,such as large delay,data packet loss,slow convergence speed,long time to find the optimal link,and the performance degradation caused by the defects of ant colony algorithm,this paper introduces GA-AC heuristic algorithm into AODV routing protocol.This paper proposes A GA-AODV routing protocol based on gene-ant colony fusion.This protocol combines the characteristics of AODV routing protocol,complements the advantages of genetic algorithm and ant colony algorithm,and can solve the above problems well.Finally,the G-A-AODV simulation experiments were established by network model,node model and process model in OPNET simulation platform.The simulation data were verified and analyzed by repeated experiments in large-scale mesh＿big scenario and small-scale mesh＿little scenario.Compared with AODV and A-AODV routing protocols,the proposed G-A-AODV routing protocol has improved latency,throughput rate and bandwidth resource utilization,which has certain theoretical and application value.Figure 36 Table 7 Reference 73...
