摘要:
提出一种应用于车辆自组织网络的功率控制算法.首先给出系统吞吐量优化的理论分析和仿真分析,指出当网络中车辆节点数为15时,系统吞吐量达到最大.然后设计了基于车辆探测消息的功率控制算法,算法中每个车辆节点周期性地发送探测信息,并根据接收到的其他车辆信息,分析出网络中车辆节点数目以及网络的前后连通状态,继而通过自动调整发射功率来改变网络拥塞状况,给出了算法的详细流程.仿真结果表明,采用功率控制算法的VANET系统,其传输时延随车辆节点数的变化几乎始终保持在约24ms的较低水平,同时系统吞吐量稳定在最大值.
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.
