The Research Of Performance Measurement Software For Wireless Optical Communication

Wireless optical communication, a kind of fiber-free communication technology, is also called free space optical communication (FSO). It was made up of laser transmitter, optical receiver and some control equipments. As a kind of wireless access technology, wireless optical access has many virtues such as large capacity, low cost, convenient deployment and flexibility since it integrates the advantages of fiber communication and other traditional wireless communication technologies.However, the channel of wireless optical communication is atmosphere channel, which will badly affect the stability and reliability of the wireless optical communication. The main purposes of performance measurement are to detect the bottleneck of the network, optimize the network deployment, to discover the potential risks, to get more effective performance management, to provide the validation and control of the service quality in network, and thus to validate, compare and measure the indicators of service quality.Combination of the characteristics of wireless optical communication, this paper introduces a design idea of network performance measurement system, which is used in wireless optical communication system and is expediently fixed and manipulated. Based on the embedded hardware development board, we structured a special software platform for this system. The important point is the design of the network performance measurement system in software. This paper include the implementation of measurement module, communication module, stakeout module, control module and storage module based on socket communication and VC++ program technology. Finally, the work of this paper and some specific advices were summarized, which pave well the way for the practical development.
