Developing an Enhanced NAT-Traversal Approach for Collaborative Augmented Reality e-Maintenance Platforms

International audienceThis paper describes our ongoing efforts towards the development of a real-time communication module for collaborative augmented reality e-maintenance platforms. This module allows technicians and remote experts to stream video, audio and other specific structured/unstructured data application (commands, text messages, markers coordinates, virtual objects parameters, etc.) either in peer-to-peer model or using relay servers. Taking advantages from detecting local configurations of networks allows optimizing paths of data streams between technicians and experts. This is mainly done by comparing with current solutions, when technicians and experts are in the same local network, data streams would not need to be forwarded over the Internet
