This paper describes a field demonstration and presents the network performance of an 802.11 ground-UAV network composed of 11 ground stations, a mobile vehicle and two fixed wing UAVs, connected by two routing gateways to a legacy wired network. The network effects demonstrated include mobility, network partitions and merges, and gateway failovers. The paper presents experimental results for recorded...
We present CORE (common open research emulator), a real-time network emulator that allows rapid instantiation of hybrid topologies composed of both real hardware and virtual network nodes. CORE uses FreeBSD network stack virtualization to extend physical networks for planning, testing and development, without the need for expensive hardware deployments. We evaluate CORE in wired and wireless settings,...
A current challenge in interconnecting mobile ad hoc networks (MANETs) with backbone legacy networks is the lack of compatibility between different multicast routing protocols when using multiple gateways, due to differences in both forwarding semantics and implementations of the different protocols. We present designs and experimental results involving the interconnection of the simplified multicast...
The open shortest path first (OSPF) routing protocol performs inefficiently when operated over certain types of mobile ad hoc networks (MANETs), such as those formed by using IEEE 802.11 ad hoc radios. In 2003, the Internet Engineering Task Force (IETF) OSPF working group solicited proposals to extend OSPFv3 for IPv6 to operate efficiently in MANET environments. During design team consideration, two...
