摘要
针对无线多媒体传感器网络对带宽和实时性等的高要求,建立了一种基于能量优化和跨层协同交互的分布式多路径路由技术,并应用于移动通信领域。该技术采用了遗传算法优化节点传输多媒体数据能耗,建立节点剩余能量预测模型,根据感知能量建立跨层协同工作体系,以较小代价在动态无线网络拓扑中选择最优路径。仿真实验和数学分析表明,该技术能够高效地支持实时移动视频通信,适合于计算能力、存储能力和能量等受限的无线多媒体传感器网络。
For wireless multimedia sensor network bandwidth and real-time,high demand,this paper built a kind to be based on energy optimization and cross-layer interactive distributed multi path routing technology and application in the field of mobile communication.The first,it used genetic algorithm to optimize the node to transmit multimedia data establishment of residual energy of nodes energy consumption prediction model,and then according to the perception of the energy based cross-layer coordination work system,with lesser cost in dynamic wireless network topology optimal path.Simulation experiment and mathematical analysis show that,the technology can effectively support the real-time mobile video communication,suitable for computation ability,memory ability and energy constrained wireless multimedia sensor networks
