Abstract:MaritimeManet is a Mobile Ad-hoc Network (MANET) using directional antennas for full 360-degree coverage, creating a long-range IEEE 802.11s mesh network for maritime environments. This study investigates the effectiveness of multicast video streaming over MaritimeManet using optimizations in B.A.T.M.A.N. advanced (BATMAN-adv). Communication issues in the digital twin environment, notably VLAN-related packet loss, were resolved to ensure reliable testing. Three multicast optimizations in BATMAN-adv, dedicated multicast packets, multicast as unicast, and multicast as broadcast, were evaluated under varying network conditions. Results show that broadcast yields artificially high throughput due to simulation artifacts, while multicast as unicast suffers from uneven performance at higher loads. The dedicated multicast packet mechanism delivers the most stable performance over all the tested network conditions, making it the preferred option for multicast video streaming in MaritimeManet.
