摘　　要：在多媒体无线传感器网络中,网络信道密集,路由表转发和链路估计过程中会在网络密集信道中产生间歇性混叠谱。混叠谱频段消耗大量能量,需要对间歇性混叠谱频段的功耗进行负载均衡设计,提高网络的生存能力。提出一种基于路由引擎链路转发机制的网络密集信道间歇性混叠谱频段功耗测试方法,实现网络的负载与功耗的均衡。构建WMSN路由节点数据传输模型与网络模型,分析网络密集信道中的间歇性混叠谱的产生激励及能量消耗计算方法,得到无线传感器网络中各个节点发射信号能量脉冲偏移,计算路由引擎链路转发机制下的间歇性混叠频段联合特征均方误差,实现网络的负载与功耗的均衡,达到网络密集信道中间歇性混叠频段功耗测试的目的。仿真实验表明,该算法具有较好的功耗负载均衡性能,传输相同多媒体视频信息数据,功耗测试表明算法能节省能量开销45%,从而提高了网络的生存能力。In multimedia wireless sensor networks, network channels of dense, routing forwarding and link estimation in the process of network intensive channels generate intermittent aliasing spectrum. Aliasing spectrum band consume a lot of energy, the need for intermittent mixing power spectral band stack load balancing design, enhance the network survivability.A routing engine link transmission mechanism based on network intensive channel intermittent aliasing spectrum band power test method, load and power equilibrium network. Construction of WMSN routing node data transmission model and network model, analysis of network intensive intermittent channel aliasing spectra generated motivation and energy consumption calculation method, get the wireless sensor network nodes transmit signal pulse energy calculation of offset, the routing engine link to intermittent mechanism under the mixed character overlapping bands mean square error, the realization of load and the power consumption of the network, to achieve network dense channel intermittent aliasing frequency power test purpose. Simulation results show that the algorithm has good performance of the power load. With the same multimedia video information transmission, the power test can save the energy cost of 45%, so as to improve the survivability of the network.
