However, the amount of data transmitted daily and the automation of data recording makes it impossible to use any data transmission method besides the Internet.
At present, the data transmission method is mainly based on two kinds of communication architecture [7]: (1) V2V or V2I communication architecture based on DSRC and (2) vehicle networking communication architecture based on the mobile gateway.
However, although the data transmission method based on Dedicated Short Range Communication (DSRC) can transmit the data to the node of the vehicle, the data transmission quality of service (QoS) is hard to guarantee.
In the future, however, we will base this on real traffic scenarios, combined with uplink and downlink data transmission methods, and use the transmission and distribution of data to expand further research and verification.
So, the previous static opportunistic network algorithm [6], data stream computing method, and fixed cooperation transmission method of cooperative communication algorithm have been unable to satisfy the diversity of data stream application over wireless sensor networks.
We also discuss the main idea of simultaneous data transmission and the method of pre-calculating the transmit/reception masks.
Using the parameters in Table 3 and Eq. (7), we could obtain the average required data transmission power of three different transmission methods when different SNR levels are used in the simulation.
The effects of different methods of data transmission, number of clients, and roaming among different access points on the file transfer rate were determined.
Data transmission process of the MUCON protocol is using direct methods.
Therefore, a single method of data transmission cannot meet the demands of message forwarding under different traffic flow scenarios.
