Abstract-- The per-node throughput capacity of hybrid radio
frequency and free space optics (RF/FSO) networks is studied
and the benefit of using this hybrid network architecture over
the pure RF wireless networks is evaluated. The hybrid RF/FSO
network consists of an RF ad hoc network of n nodes, m of them
(so called super nodes) are equipped with an additional FSO
transceiver. Every RF and FSO transceiver is able to transmit
at a maximum data rate of W1 and W2 bits/sec, respectively.
All the super node are connected by the FSO links and thus
can form a stand-alone FSO network. With a minimum transmit
power objective, an upper bound on the per node capacity of
