A novel mobile position location procedure, based on the relaying capability of the mobile stations in a hybrid cellular/peer-to-peer ad hoc network to improve positioning coverage and accuracy, is proposed. The proposed mobile location scheme is a hierarchical-structured flooding procedure, making use of the relaying capability of mobile stations to achieve location diversity. Simulation results show that the proposed positioning scheme offers improvement in coverage and accuracy compared to conventional positioning methods reported in the literature. With the increase of the mobiles in the system, the coverage of the conventional system does not change. However, the coverage of the proposed discovery mechanism monotonically increases towards 100% by exploiting location diversity. The gain of the coverage is also promising when cell size is large, where the conventional methods suffer the hearability problem
