Mixed Reality (MxR) represents an emerging technological paradigm, involving the merger of real and virtual environments to enable physical and digital objects to co-exist and interact in real time. Prior research efforts demonstrate the potential of MxR systems as decision support aids for Soldiers, capable of providing enhanced battlefield Situational Awareness (SA). Towards providing needed content ingest for MxR decision support, Internet of Things (IoT) based services appear to show growing promise. Ongoing advances in IoT technology have resulted in steady growth in both quantity of IoT assets deployed and data generated globally. However, towards supporting IoTMxR systems integration in battlefield environments, novel methods are presently required to support ingest and management of digital content for MxR device users. This paper provides discussion on supporting tools and techniques to support MxR-IoT integration as a means of decision support. Here, focus will be placed on both leveraging of existing IoT middleware solutions as well as methods for Value of Information (VoI) assessment according to consumer needs.
