Visible light communications (VLC) have gained popularity as an alternative to RF. Understanding the underlying communications is key to the design of MAC protocols for arbitrating access across lights in multiple rooms. We consider the interference across two rooms from VLC emitters. The emitters use Binary Pulse Position Modulation (BPPM); the pulse width is varied to provide different dimming levels...
The solar blind ultraviolet (UV) scattering channel makes non-line-of-sight UV communications very attractive for military applications, particularly for communication on-the-move with low probability of detection and low probability of interception. Despite significant research effort on the UV physical layer, work on protocol design at the upper layers is quite limited. We consider a mobile ad hoc...
