摘　　要：对复杂网络与无线ad hoc网络的机理分析表明,一定条件下的无线ad hoc网络具有复杂网络效应。该文在验证多射频节点组建小世界无线ad hoc网络可行性基础上提出多射频节点的控制策略。文中提出的策略考虑到节点的设计,并根据网络环境及节点的聚类系数来控制多射频节点的部署。仿真实验表明,该策略优化了网络的拓扑结构,增加了网络的鲁棒性,对进一步优化网络性能具有理论与实际意义。Analysis of the mechanism of complex networks and wireless ad hoc networks shows that wireless ad hoc networks under certain conditions have complex network effects.A control strategy for multi-radio nodes is proposed based on the feasibility of small-world wireless ad hoc networks with multiple radio nodes.Taking into consideration the node design,the deployment of multi-radio nodes is controlled according to the network environment and clustering coefficient of the nodes.The results show that the proposed method optimizes the network topology,and increases the network＇s robustness.It has theoretical and practical significance to further network optimization.
