Protocol adaptation in hybrid RF/optical wireless networks

One of the major challenges in network-centric warfare is the ability to connect nodes with very high-capacity links. For example, sensor data dissemination is fundamental to network-centric warfare and yet it may overwhelm many available RF communication links. Free-space optical communications (FSOC) has the potential to meet this emerging military need by offering dramatic increases in bandwidth. This technology is not without significant technical challenges such as acquisition/tracking and mitigating the effects of propagation, so multi-band hybrid capabilities are likely to be needed. This diversity of systems provides a degree of robustness that is required for the assured ability to communicate in military operations. This paper will examine protocols and technical approaches for hybrid RF/optical tactical wireless networks
