Jamming effects on multicast traffic in ad hoc networks for different terrains

The paper examines mobile TDMA-based ad hoc networks exposed to follower jamming. The focus is to examine how the terrain and network protocols influence jamming resistance. To study the network properties under follower jamming, network simulations are performed. The investigated networks in a flat terrain become more jammed than the corresponding networks in a hilly terrain. The packet delivery ratio is measured when the network protocol OLSR MPR-flooding is used and compared with a network using full flooding. Even if not as robust as full flooding, we show that OLSR MPR-flooding is still relatively robust. We also show that it is sufficient to jam the OLSR control traffic used by the network protocol to have a serious impact on the packet delivery ratio.
