Collaborative Sensor Network Localization: Algorithms and Practical Issues
Emerging communication network applications including fifth generation (5G) cellular and the Internet of Things (IoT) will almost certainly require location information at as many network nodes as possible. Given the energy requirements and lack of indoor coverage of Global Positioning System (GPS) collaborative localization appears to be a powerful tool for such networks. In this paper, we survey the state of the art in collaborative localization with an eye toward 5G cellular and IoT applications. In particular, we discuss theoretical limits, algorithms, and practical challenges associated with collaborative localization based on range based as well as range angle based techniques.
