摘　　要：无线多媒体传感网络采用无线信号完成通信,会受到网络带宽的限制,实时传递能量较低,限制多媒体数据的传输。提出一种基于改进蚁群算法的无线多媒体传感网络的路由结构优化方法,根据改进蚁群算法,设计无线多媒体传感网络路由模块的硬件构造,改进无线多媒体传感网络路由优化过程,通过改进基本蚁群算法中的转移概率模型,对蚁群移动概率进行完善,确保负载的均衡,实现路由结构优化设计。实验结果说明,所提方法对无线多媒体网络中的路由结构进行改进后,均衡了网络能量消耗,使得无线传感网络节点的平均剩余能量更多,提高无线多媒体传感网络的运转周期。The wireless multimedia sensor network uses the wireless signal to communicate,which is limited by the network bandwidth,so it results in low real-time transfer energy,and limits the multimedia data transmission. A routing structure optimization method of wireless multimedia sensor network based on improved ant colony algorithm is proposed. On the basis of the improved ant colony algorithm,the hardware structure of the wireless multimedia sensor network routing module was designed,and the optimization process of the wireless multimedia sensor network routing was improved. The transition probability model of the improved basic ant colony algorithm is employed to perfect the ant colony movement probability,ensure the load balance,and realize the routing structure optimization design. The experimental results indicate that the proposed method used to improve the routing structure in wireless multimedia network can balance the network energy consumption,increase the average residual energy of the wireless sensor network nodes,and improve the running period of the wireless multimedia sensor network.
