摘要：

To improve the low indoor localization accuracy, a grid-based indoor cooperation localization algorithm (GICLA) in wireless networks was proposed through collaborative localization of heterogeneous networks. A signal covering region was divided into several grids, many kinds of signal information of these networks were gotten, and the localization ability of grids was judged, which was different from single localization mode in all regions. GICLA assigned different weight to each network in each grid, determined whether multi-networks were cooperative, and analyzed and obtained the optimal localization combination scheme. Moreover, GICLA can also be applied to outdoor localization directly when it collects outdoor signals of different networks in offline phase and expands the cooperation localization fingerprint database. Simulation results show that GICLA outperforms single network localization algorithm and the equal weight allocating algorithm. GICLA improves localization accuracy and localization ability rate of the covered region. ©, 2015, Huazhong University of Science and Technology. All right reserved.
