Wireless networking has conventionally been realized via radio frequency (RF) based communication technologies. Main issue with RF networks is that end-to-end pernode throughput approaches zero as new nodes are added to the network. To overcome this throughput problem, we propose a multi-element optical antenna design that successfully exploits spatial reuse of the shared medium. In this design, each freespace-optical (FSO) transceiver (transmitter, receiver pair) element on a node is capable

We simulated networks of such nodes and found that FSO-based directional communication provides multiple times better channel usage. However, FSO nodes suffer from mobility for instance, since slight movement of communicating nodes can cause them to be misaligned, resulting in intermittent connectivity. In this thesis we present our findings related to free-space-optical mobile ad hoc networks (FSO-MANETs), effect of individual system parameters on transport level capacity scaling and compare FSO with RF networks within the context of MANETs. iii
