摘要:

提出了一种基于混合博弈的Ad hoc网络多信道选择算法,以最大化每个节点吞吐量为目标,研究了在多个信道速率不同的情况下节点对接入信道的选择问题. 首先通过建立饱和吞吐量模型来量化节点选择不同信道所获得的收益,然后利用混合博弈纳什均衡理论分析不同用户数时的信道选择策略,并提出一种混合策略信道选择算法,以最大化每个节点的吞吐量,同时保证了信道分配的公平性. 仿真结果表明,该算法能较大地提高系统吞吐量,在多用户竞争情况下,与随机选择和共享信道等策略相比,吞吐量至少提高了15%.

Abstract:

A mixed strategy algorithm based on the mixed-game theory is presented to maximize the node overall throughput in asymmetric multi-channel Ad hoc networks. First, a simple saturation throughput model is presented to quantify to the utility of each node, then, the mixed-game Nash equilibrium model is used to analyze the channel selections. At last, the mixed strategy channel selection algorithm is proposed to maximize the throughput and also improve the fairness of channel selections. Simulation results show that the algorithm can achieve at least 15% improvement compared with random strategy and shared channel selections in multi-user scenarios.

Key words: Ad hoc networks, mixed-game, channel selection, throughput
