中文摘要：

为了提高无线Ad hoc网络中的Multi-radio Multi-channel利用率,最大化全网吞吐量,提出了一种基于协议冲突模型的功率分配算法-LPCA。LPCA首先利用整数线性规划方法得到了最小功率下所有链路并行传送数据所需的最小信道数,然后又分别估计了相同功率和混合功率下Multi-radio Multi-channel网络的吞吐量上界。实验结果表明,LPCA算法能较好的利用多信道资源,有效地提高网络的吞吐量等性能。

In order to take full advantage of multi-channel resources and improve the network throughput,a power allocation algorithm LPCA based on protocol conflict model is proposed.LPCA firstly present the minimum number of needed channels which guarantees that all send-receive node pairs can transmit data in parallel under minimum power level using integer linear programming model.Then,It is analyzed the throughput upper bound using the same power level and hybrid power levels.Finally,the experimental results indicate that the algorithm proposed increases the channel utilization and improves throughput significantly.
