QAM_modu_and_demodu

performance evaluation of reactive and proactive protocols. the performance is evaluated with respect to throughput over TCP and UDP connections types

基于UDP通讯服务器的开发，主要负责接收传感器发送上来的检测数据，校验后解析（ＣＲＣ校验），并存储在ＳＱＬ数据库中。(UDP communication server-based development, primarily responsible for receiving the sensor sends up the detection data checksum (CRC check) after parsing, and stored in an SQL database.)
