Joint Optimization of Anchor Deployment and Power Allocation in Wireless Network Localization

In this letter, we propose an optimization based method for joint anchor deployment and power allocation for achieving high-accuracy localization in the wireless network, where we aim at minimizing the localization error bound under a given sensor number and a fixed power budget. By exploiting squared position error bound as the localization metric, the problem is formulated into a mixed boolean second order cone programming, and is then solved by binary particle swarm optimization. Finally, the proposed algorithm is validated by numerical simulations.
