Özet

Heterogenous networks (HetNets) using different size cells and several different networks with multiple wireless access technologies can provide large capacities while also improving the localization accuracy. In this paper, we propose a novel received signal strength (RSS) based inter-network cooperative localization framework based on a Metropolis-Hastings (MH) algorithm for two-tier HetNets with unknown transmit powers. Through the MH based estimation methodology, the unknown position of user equipment and transmit powers of base stations (BSs) are jointly estimated. The validity of the proposed method is confirmed by simulation results.
