Mobile devices, smartphones and tablets, are continually expanding their computational performance capabilities through improved processing, interconnectivity network abilities, resource management and ease of use user interfaces. As such they are gaining interestas a means tosupport on-the-move remote collaboration for military personnel executing real time decision making tasks. This paper focuses on a software-based implementation of a prototype multimodal Android application that was designed to capture and disseminate real time battlefield perspectives to distributed entities. Moreover the mobile application enables remote experts to interactively collaborate through multimodal functionality to provide directives to the mobile userthat should be applied to the local …

A thorough understanding of the network behaviour when exposed to challenges is of paramount importance to construct a resilient MANET (mobile ad hoc network). However, modelling mobile and wireless networks as well as challenges against them is non-trivial due to dynamic and intermittent connectivity caused by channel fading and mobility of the nodes. We treat MANETs as time-varying graphs (TVGs) represented as a weighted adjacency matrix, in which the weights denote the link availability. We present how centrality-based attacks could affect network performance for different routing protocols. Furthermore, we model propagation loss models that represent realistic area-based challenges in wireless …

End-to-end communication in highly-dynamic airborne networks is challenging due to the presence of highly mobile nodes and the inherent nature of wireless communication channels. Domain-specific protocols are required that can address these challenges and enable reliable transmission of data in this environment. We develop the ANTP (airborne network and transport protocols) suite that operates in this highly-dynamic environment while utilising cross-layer optimisations between the physical, MAC, network, and transport layers. We show how each component in the ANTP suite outperforms the traditional TCP/IP and MANET protocols through simulation using ns-3. Having verified these protocols through simulation and analysis, the next …
