摘　　要：覆盖问题始终是无线多媒体传感器网络(WMSN)中研究的重要领域。为了实现对被监测区域的全方位覆盖,以及能够捕捉到进入该区域目标的有效信息,同时尽可能延长网络寿命,提出了一种基于异构节点的全视角强栅栏覆盖模型,借助红外线传感器辅助相机传感器节点完成对一个指定区域的监测。在研究过程中,受到了分治策略的启发,将目标区域分为若干正三角形网格,采用唤醒机制有效节约网络能量。仿真实验表明,该模型能够通过消耗较少的能量,实现对一个区域的覆盖监测,延长了网络寿命。In the study of wireless multimedia sensor networks （WMSN）, the coverage issue had been always an important area. In order to achieve full-view coverage of the monitored area, as well as to capture the effective information which entered the area, meanwhile, as far as possible to extend the network life, this paper proposed a model based on heterogeneous nodes of full-view strong barrier coverage in WMSN. It used infrared sensors to assist the camera sensor nodes to achieve a designated area monitoring. During the study, inspired by the divide and conquer strategy, it divided the target area into several grid of equilateral triangles, used wake-up mechanism to save networks energy effectively. Simulation results show that this model can consume the less energy to achieve coverage monitoring of an area and prolong the network lifetime.
