Abstract: A wireless connection scheme,named six synchronous successive transmission (SSST),is presented.The network using this scheme is called SSST network.It is mainly used for the real time radio scenario where multiple slave nodes request to send data to a master node.It has the same working frequency band with the Bluetooh.Based on SSST,slave nodes are allowed to send data transmission requests after synchronous packets are received from the master only.Slaves send their requests in an arranged way.The master transmits six synchronous packets continuously,each of which has a different index.The SSST protocol is collision free when multiple slaves require connecting the master simultaneously.The slave with the higher priority can be selected to access the network first,and the response time of each consecutive stage is easy to predict.All these are just the important features that real-time applications should have.The related theories are demonstrated and verified with experiments,and compared with the advertising and scanning of the Bluetooth.

Key words: Master node, Priority, Real time wireless network, Six synchronous successive transmission, Slave node, Slot
