摘要

本文提出了一种新的自组网联合同步与定位算法。所提出的算法基于广播消息传递，消息数量与节点数量成线性关系，而基于双向消息交换的技术是二次型的。通过引入定位约束，提高了网络同步问题的可识别性。因此，该算法不需要完整的测量集。利用基于无线局域网规范的模型给出了数值结果。在数据缺失的情况下，与常用的同步和定位技术相比，该算法显著提高了同步和定位性能。

Cooperative joint synchronization and localization using time delay measurements

In this paper a novel algorithm is proposed for joint synchronization and localization in ad hoc networks. The proposed algorithm is based on broadcast messaging, with number of messages linear to the number of nodes, versus quadratic for techniques based on two-way message exchange. The identifiability of network synchronization problem is improved by introducing localization constraints. Hence, the proposed algorithm does not require a full set of measurements. Numerical results are provided using a model based on wireless LAN specifications. In scenarios with missing data, the proposed algorithm significantly improves synchronization and localization performance compared to commonly used techniques.
