The invention relates to a method for wireless function deployment of a low-cost HOWBAN (Hybrid Optical-Wireless Broadband Access Network) with survivable perception, belonging to the technical field of optical wireless hybrid network communication. The method aims at the problems that the existing survivable protection mechanism cannot carry out reasonable wireless function deployment on ONUs (Optical Network Unit) thereof according to the survivability guarantee level of a network, and data affected by a fault is only forwarded between some ONUs, and the wireless function deployment is carried out on all ONUs in the network to cause reduction of the network resource utilization rate and higher deployment cost, and furthermore, a quantitative analysis method is adopted to evaluate the network survivability, so that the network reliability is obtained by accurately quantizing the current wireless function deployment condition of the ONUs, and thus a multi-target optimization method is utilized to effectively balance the network cost and the network reliability, and the wireless function deployment of the ONUs is completed with the maximum resource utilization rate as a target. According to the method, the network survivability can be met while the purposes of improving the network resource utilization rate and reducing the network cost are achieved.
