Design And Implementation Of Wireless Accessed Network Performance Meassurement Probe

In recent years,with the rapid development of the Internet and mobile devices,mobile Internet has been integrated into people’s production and life,and is changing the way people live.The rapid development of the network at the same time,people on the network quality of service to the growing demands,while increasing network traffic so that network operators face the challenge.Network measurement,particularly large-scale wireless network measurement environment,as a method of evaluating network performance,enhance the method the user experience,more and more attention network operators and researchers.Also,how to accurately measure network parameters and comprehensive evaluation of the performance of wireless network environment,it has become a hot topic at native and abroad.At present domestic and international research work on network performance measurement in wireless environment focused on two aspects,one is measuring algorithm based on wireless network theory underlying principle,on the other hand is the study of wireless network performance indicators based on statistical principles;But for the development of the wireless network platform to build measurement and measurement tools,the outcome is less.Wireless network compared with wired networks,its performance characteristics are more complex,network-layer performance measurement algorithm parameters on a wireless network also needs to be improved accuracy,and more importantly,the need for a large-scale measurement platform,capable of wireless environment network performance under the orderly,efficient measurements and measurement data can be collected for further research;therefore,based on a combination wireless access network performance measurement probe and measurement system TANC large-scale network,a good fit wireless network measurement research needs.The main function of the network performance measurement probe wireless environment measurement task is initiated,the collection of measurement data,upload the measurement results,and the user TANC centralized management platform can be observed in real-time measurement of the progress and results of the measurement.Therefore,the goal of this paper is to study under the premise of wireless access,to implement an accurate,efficient network performance measurement probe which can fit the TANC large-scale measurement system,to study ad hoc wireless transmission of measurement data and the method of measuring the collection and transmission of data.From the perspective of design and implementation,network performance measurement probe-based wireless access has been fully elaborated.First,the development of related technologies used in the process were discussed,including TANC measurement system,Android related technologies,multi-threading technology and related network parameter measurement algorithms;then the wireless probe demand analysis,including the system components,functions requirements and non-functional requirements of three parts;then the wireless probes carried out a detailed design and implementation,including the design and implementation of the overall architecture and the design and implementation of each module;and finally the characteristics of the wireless probes were improved and perfected,including lifting and storing the measurement data of the measurement accuracy;and performs a test on each of the building blocks,are discussed test procedures and test results in detail,meanwhile the test results of the wireless network probes are analyzed.
