Abstract

Abstract : Accurate position information is the basis of many modern wireless applications. Hybrid time of arrival/angle of arrival (TOA/AOA) measurements are attractive in location‐aware networks, especially when the number of anchors is limited. Recent investigations show that proper resource allocation is of great importance in cost and complexity restricted localisation networks. In this study, the authors focus on the energy efficient localisation strategy using hybrid TOA/AOA measurements. A joint resource allocation and antenna selection framework is presented to minimise the localisation error. Due to the essential non‐convexity of the original formulated integer programming problem, a low complexity and high accuracy two‐phase solution is presented to perform proper convex relaxations. Numeric results validate the authors' analysis, and provide meaningful insights to practical TOA/AOA localisation networks.
