Previous research on Physical-layer Network Coding (PNC) focuses on the improvements in bandwidth usage efficiency. Its capability to assist wireless nodes in localization was first discussed. In that paper, however, the authors discussed only the basic idea to detect and separate the interfered signals for calculating the node positions. Many important issues to turn the idea into a practical approach are not extensively studied. In this paper, the authors plan to investigate these problems. Specifically, their research focuses on the bootstrap procedures, security, and localization accuracy of the PNC based mechanism. They first study the required node density to bootstrap the localization procedure in both infrastructure-based and self-organized networks.
