Optimization Technology And Verification Of Large-Scale Ad Hoc Network Resource Management And Dedicated Control Channel

Wireless Ad Hoc network(WLAN),as a kind of non-center network,has been widely used in civil and military fields by virtue of its environmental adaptability and strong destructiveness.With the complexity of Ad Hoc networking application scenarios,the number of nodes in the network is increasing gradually,but the time-frequency resources provided by wireless channels are limited,which brings problems such as rationality and validity of time-frequency allocation and routing reliability to large-scale node networking.In order to solve these problems,this paper proposes a multi-node resource management method under dedicated control channel,which can realize low delay and high efficiency access and routing while guaranteeing service Qo S.The main research work of this paper is as follows:Firstly,the research status of dynamic time-frequency resource management in wireless Ad Hoc network is investigated.This paper lists typical time-frequency resource management algorithms and summarizes the main problems of resource allocation in wireless Ad Hoc networks.This paper describes the typical application scenarios of large-scale node networking,and analyzes the networking function requirements and key performance indicators in this scenario.Secondly,the optimization technology of resource management and dedicated control channel of large-scale Ad Hoc network is studied.Aiming at typical large-scale networking scenarios,this paper proposes a "cross-layer design" resource allocation method by referring to the TCP/IP five-layer protocol model and combining static and dynamic resource management.This paper introduces in detail the service classification of the transport layer,the data routing algorithm of the network layer and the time-frequency application and release process of the MAC layer.Finally,the network system’s handling methods are given when nodes fall off the network or time-frequency conflicts.Thirdly,based on Xilinx Zynq-7035 hardware platform,resource management and dedicated control channel optimization techniques are implemented in this paper.The working principle of each thread in transport layer,network layer and MAC layer is explained,the design of data interface between each layer is given,and the test and verification of the whole protocol is completed.The test results show that the protocol can achieve a success rate of more than 90% in the static simulation multi-node test.In the range of network simulation,the network system with 80 nodes can achieve the network throughput of more than 30 Mbps and the data packet loss rate of less than10%.Through the analysis of the test results,the proposed large-scale Ad Hoc network resource management and dedicated control channel optimization technology can better solve the resource allocation conflict,low network capacity,high packet loss rate and other problems under the condition of large-scale node networking,and provide technical support for the application of large-scale wireless Ad Hoc network in typical scenarios.
