In this thesis, we present a detailed analysis of hybrid point-to-multipoint free
space optical (FSO)/radio frequency (RF) wireless system. Hybrid FSO/RF sys-
tems have emerged as a promising solution for high data rate wireless transmission.
FSO technology can be used effectively in multiuser scenarios to support Point-to-
Multi-Point (P2MP) networks. In this P2MP network, FSO links are used for data
transmission from a central location to multiple users. When more than one FSO link
fail, the central node uses a common backup RF link to transmit a frame to a remote
node using an equal priority protocol. An equal priority protocol means that the
remote nodes have the same priorities in being assigned the RF link. We assume two
traffic classes, a high-priority and low-priority classes. The base station reserves two
transmit buffers of each user for the downlink transmission. Considering the downlink
traffic from the base station to a tagged remote node, we study several performance
metrics. We develop a cross-layer Markov chain model to study the throughput from
central node to a remote node as well as the performance of the resulting system. / Graduate
