摘　　要：针对现有感知模型无法有效描述无线多媒体传感器真实感知能力的缺陷,提出一种新的三维有向感知模型。在此基础上,针对目标覆盖问题,为降低算法复杂度,设计了一种基于仰俯角优化和偏向角优化的两阶段目标覆盖算法。对于仰俯角和偏向角优化部分,利用差分进化算法进行求解,以达到利用少量传感器节点实现监测目标被全部覆盖的效果。仿真实验表明:对比随机部署方法,本文方法所需的传感器数目大幅下降。The existing traditional perception models can not characterize the real perception ability of wireless multimedia sensor node accurately.To overcome this shortcoming a novel three-dimensional directional perception model is proposed.On this basis,a target coverage algorithm is designed based on the optimization of tilt angle and deviation angle instead of adjusting the main perception directions to solve the all targets coverage problem.The title angle and deviation angle are optimized based on differential evolution algorithm in order to use fewer sensors to cover all targets.Simulation results show that the proposed method requires less number of sensors to cover all targets than random deployment.
