In recent years there has been a growing trend in optical wireless convergence.One particular aspect of this is 60 GHz radio-over-fiber technology. It is intended for usein wireless personal area networks. However, we think that the same technology could beused for monitoring applications in the indoor environment. It could be used to detectemergency situations or to detect intruders. We shall examine reasons why this choicemight be a suitable one. We shall then propose a MAC layer protocol to accomplish thistask. Since in case of emergency we might require to obtain data from only one node foran extended duration, flexibility in implementation is required. We shall develop anadaptive MAC protocol where this would be possible. We accomplish this by includingtwo protocol modes called the Icarus mode, which is to be used in case of an emergencyand the Resync mode which is used when normality is restored. A significant problem athigh frequencies is that the beam becomes increasingly narrow and behaves more in a raylike condition. This implies that particularly in an indoor environment it is possible thatthe beam may be accidentally blocked. In this case the node must be able shift the beamin order to enable communication. We demonstrate three such strategies and offer acomparative analysis.
