Abstract: Quality of Service - QoS provisioning during routing in Mobile Ad-Hoc Networks has been an exigent task for researchers since long. The challenges like node mobility, route maintenance during topology changes and link characteristics become more sophisticated if the scenario requires maintaining clear Line of Sight (LOS) between the transmitter and receiver. Similar is the case of a Free Space Optical Mobile Ad Hoc network (FSO MANET), which was originally designed for military applications and Delay Tolerant Networks. Routing for successful delivery of data and efficient utilisation of network bandwidth remains a challenging issue till date in such networks. A routing protocol should take care of directional nature of transmission and LOS requirement in a transceiver pair in FSO MANET. In this work the traditional routing protocol Ad Hoc On-Demand Distance Vector-AODV is implemented in an FSO MANET to satisfy the QoS requirement-bandwidth. The results showed an improvement in throughput if bandwidth is pre-specified as QoS parameter. The performance is evaluated by varying node speeds and varying the number of nodes in the network.
