Abstract:
A power control algorithm applied in vehicular ad hoc network is presented. Firstly, the optimal number of active users which is 15 in the network is given on the basis of optimization of system throughout by theory analysis and simulation analysis. Then, the number of active users in the network can be obtained by receiving the periodic probe messages. The model of the communication connecting status can be established as well. The power control algorithm is designed in which the vehicles adjust their transmission power to control the congestion of the network and the process is presented in detail. The simulation results show that with the algorithm proposed the transmission delay can keep at a lower level of about 24ms and the optimal system throughput can be achieved.
