摘　　要：针对现有的有向传感器节点的感知模型应用中,在感知范围两侧的边缘处易受误差影响而使得此处感知能力的不确定,致使整个网络的覆盖情况不稳定的问题,设计了一种有向概率感知模型。该模型参考了全向概率感知模型,同时考虑到了节点的转动误差,更加准确地描述了有向传感器节点的感知能力。经仿真验证,该模型具有较好的应用效果。The existing directional sensing models are always affected by uncertain sensing ability on their edges of two sides in application of the models, leading the whole network instable. In this paper, a probabilistic sensing model for directional sensor node is designed, omni-sensing model and rotation error are both considered in this model. According to the simulation results, the model is proved to be effective in the application.
