Research On Intelligent Optimization Routing Of Mobile Ad Hoc Networks In Coal Mine

In the process of safety monitoring and production operations in coal mines,data transmission requires the support of communication infrastructure.These infrastructures may be destroyed in the harsh underground environment,resulting in data transmission failure and potential safety hazards.The mobile ad hoc network can be constructed by intelligent mobile terminals carried by miners,does not depend on any infrastructure,and provides a new method for wireless transmission of mine safety monitoring data.Based on the dynamic nature of the mobile ad hoc network,this paper uses the adaptive behavior of the amoeba model to design an autonomous optimization routing algorithm to adapt to the dynamic changes of the underground wireless network topology.The algorithm introduces the parameters of the mobile ad hoc network into the Poisson equation in the Physarum model.The differential evolution equation of the Physarum model was used to evolve the parameters to reduce the complexity of the algorithm.A distributed routing decision method is proposed to construct the data transmission optimize the path and improve the service quality of data transmission.Perform simulation experiments based on the NS2 platform,compared with GPSR,PIMAR,and P-IRP routing algorithms.The results show that the autonomous optimizing routing algorithm of the mine mobile ad hoc network based on the Physarum model shows good performance in terms of average end-to-end delay,delivery rate,throughput and network survival time.The algorithm proposed in this paper achieves energy consumption and network load balance,and extends network survival time.In order to achieve better application in the actual environment such as mine,the ad hoc network needs to test the performance of the routing protocol in the real network environment.At present,the mostly researches of mobile ad hoc networks are based on simulators,and the simulation environment is very different from the real mobile ad hoc network test environment.In order to study the performance of mobile ad hoc network in real environment,this paper designs a mobile ad hoc network test platform based on embedded ARM-Linux,and transplants the corresponding routing protocol on it.This article elaborated on the construction process of mobile ad hoc network test platform,including Linux kernel transplantation,wireless network card transplantation and AODV protocol transplantation.The network performance test shows that the test platform constructed in this paper can realize the corresponding functions of the mobile ad hoc network and provide support for related research on mobile ad hoc network routing.There are 26 figures,9 tables and 69 references in this paper.
