Research and application of loom data transmission protocol based on multicast technology

In order to make up the shortcoming of the multi-looms data transmission and mass data transmission by point to point wireless transmission technology,a way of the wireless transmission by multicast technology was put forward.The technical routes of multicast transmission were introduced;the main communication protocol structure and protocol time planning were analyzed;mathematical model of transmission efficiency was built,and the transmission efficiency of unicast and multicast were analyzed by simulation.Time of unicast and multicast data transmission was tested respectively in the test platform in the workshop.The scheme of multicast technology has been proven more efficient and more stable by the test results.
