Abstract

We present a node layout algorithm based on NSGA-II for Communication and Navigation Fusion System (CNFS), to address the issue that the impact on communication service should be considered jointly in positioning network planning. CNFS mostly adopts co-site deployment scheme to reduce deployment and maintenance costs, and node layout has a significant impact on network performance. This paper employs ray tracing technique to accurately predict indoor signal propagation path, develops a set of network performance evaluation criteria, and then determines the layout scheme using RSRP, SINR and average positioning error as the objective functions of the multi-objective optimization algorithm. This algorithm can reduce the negative effects of multipath and NLOS propagation on positioning while maintaining communication performance. The simulation results show that the proposed algorithm outperforms the random layout algorithm in terms of communication and positioning network performance, with the communication performance improving by 23.5% when compared to the existing location network planning algorithm.
