“…We implemented a fault correlation system over a simulated Future Combat Systems [3] radio network implemented in the VAN testbed [6], with radios spread out over two subnets. We developed a type system and observation model to support correlation to subnet-related root causes including failure or isolation of a radio and various types of congestion in the subnet.…”

This paper describes an approach to root cause analysis and fault correlation that addresses the problems inherent in wireless military networks. 1 Root cause analysis concerns itself with identifying and correcting problems in a network. The ultimate goal of root cause analysis is to diagnose the cause for network anomalies, towards the ultimate goal of ensuring that adequate communication functionality is maintained to support the requirements of the network users. In a wired network, the diagnosis of faults is easier due to the existence of a fixed, wired topology and fixed, wired links. In the wireless networks at the tactical edge of military networks, there is no hardwired connectivity, yet there are also expectations on the network from the end users which place constraints on the operation of the network. Fault diagnosis in such networks is fundamentally different from that in wired networks. The performance of the network must be managed explicitly with respect to its user expectations, even though the network connectivity is dynamic, the network monitoring traffic must traverse the (possibly failing) network itself, and the "correct" behavior of the network against which current network state needs to be compared evolves over time. The novel features of our solution that distinguish it from existing root cause analysis techniques are (a) a dynamic model of fault, performance and security problem propagation in the network that can evolve as the definition of network correctness changes, (b) a method for distributing reasoning over this model throughout the network into independent Correlators that share information through a set of Clearinghouses to provide a global root cause correlation capability, and (c) the ability for the Correlator

This paper describes VIRMANEL, a new, open source (LGPL) tool that we developed to run experiments and evaluate protocols and algorithms on mobile multihop networks using real software and real operating systems. VIRMANEL comprises an integrated domain-specific language to define new mobility models, a Graphical User Interface to study the behavior of mobiles nodes and a controller engine that emulates a multihop mobile network by setting firewall rules between virtual machines to define network connectivity. Designed to work with OpenVZ 1 , an efficient operating system-level virtualization tool, VIRMANEL combines ease of use and efficiency by enabling the study of large networks distributed over multiple physical machines.

“…Our goal has been to develop testbed technologies that enable testing and evaluation of any application on any common operating system, given arbitrary MANET scenarios. This paper describes an extension of our previous work on Virtual Ad hoc Network (VAN) testbed technologies for testing unmodified applications over MANETs; [1][2][3][4][5][6] provide the background, including comparison with other testbed approaches. The focus of the paper is on enabling support of modeling multilevel security enclaves on mobile platforms equipped with one or multiple radios.…”

Testing of applications for tactical MANETs poses a special technical challenge due to the difficulty of conducting experiments in an ad hoc network environment at a scale larger than a few nodes. One approach is to conduct experiments in Virtual Ad hoc Network (VAN) testbeds 1 that can imitate a tactical MANET to a high level of fidelity. For applications, this is achieved by executing unmodified software in their native operating systems on the machines over an emulated platform that uses identical logical layout of the real physical platform; for the network, it is achieved by using an emulated/simulated network that behaves like a real MANET in some/all layers of the protocol stack. In this paper, we analyze the challenges and tradeoffs of realistic modeling of tactical networks with multilevel security (MLS), and present a case study of modeling BCTM-like manned ground vehicle (MGV) platforms in the VAN Testbed. Lessons learned during application development and testing performed on the model are also discussed.
