Abstract：Fiber-Wireless (FiWi) hybrid network can effectively solve the problem that people need to receive high speed service anytime and anywhere. As the key node of the FiWi network, the number and location of ONUs determine the cost and performance of the network to a great extent. In order to reduce the construction cost of FiWi network and improve network performance, an ONU deployment strategy based on improved genetic algorithm is proposed in the EPON-WIMAX hybrid network. It can minimum the number of deployed ONUs and take into account the load balancing. The simulation results show that the proposed algorithm avoids sub-optimal trap and the final number of ONU is the least, while maintaining a high load balancing level with better performance.
