Outage Performance of Transdermal Optical Wireless Links in the Presence of Pointing Errors

This paper, studies the outage performance of trans-dermal optical wireless communication links, in the presence of pointing errors. In this sense, we first present a novel tractable path gain model, which is derived through experimental results. Next, based on this model, we provide the mathematical framework that evaluates and quantifies the impact of pointing errors of transdermal links. In more detail, we obtain the closed-form expression for the outage probability of the wireless optical transdermal link, which take into account the channel particu-larities, the transmitter-receiver misalignment, the characteristics of the optical units, as well as, the physical constraints of the in-body unit. The results reveal that the pointing errors drastically affects the reliability and effectiveness of the transdermal link and should be taken into consideration when designing a transdermal optical wireless link.
