 | Despite airborne network (AN) topology design and careful planning of AN trajectories, unexpected disruptions (from hardware failures to changes in mission requirements and hostile attacks) may cause nodes not to connect to one another directly or indirectly either because they are out of one another's range or because nodes do not meet one another according to their preplanned trajectories. Since an end-to-end path within the AN is not always guaranteed, ... |

 | Future tactical networks will be complex, with severe constraints on energy and bandwidth, operating in dynamic and unpredictable environments. By exploiting the broadcast nature of the wireless medium and spatially dispersed nodes, some of the advantages of using multiple antennas can be realized through cooperation among nodes in a network. Recent work has demonstrated that cooperation can provide increased range, improved efficiency, and more reliable and longer lasting connectivity. However, ... |

 | Various approaches have been proposed in the past for monitoring a network to diagnose failures and performance bottlenecks. One such approach for efficient and effective monitoring is probing. Probes such as ICMP pings are an effective tool for detecting network nodes that have been compromised by an attacker who tries to delay or drop traffic passing through the captured node. However, an intelligent attacker may evade detection by giving preferential ... |

 | As unmanned aerial vehicle (UAV) technology and availability improves, it becomes increasingly more important to operate UAVs efficiently. Utilizing one UAV at a time is a relatively simple task, but when multiple UAVs need to be coordinated, optimal search plans can be difficult to create in a timely manner. In this thesis, we create a decision aid that generates efficient routes for multiple UAVs using dynamic programming and a limited-look-ahead ... |

 | Improvised explosive devices (IEDs) are effective weapons for insurgents targeting conventional military and security forces. Real-time information gathering about likely use of such weapons is one approach to reduce the effectiveness of IEDs. Unmanned aerial system (UASs) may provide the information gathering capability commanders need to interdict IEDs. Currently, UASs are not systematically utilized in that capacity. This research develops a routing tool that uses column-generation techniques and a greedy ... |

Anthony R Otto; AIR FORCE INST OF TECH WRIGHT-PATTERSON AFB OH DEPT OF ELECTRICAL AND COMPUTER ENGINEERING

 | Mobile wireless network protocols currently run on optimistic routing algorithms, adjusting node connectivity only when the chosen connectivity metrics, such as signal strength, pass beyond minimum thresholds. Optimistic routing has several weaknesses. Optimistic routing suffers from increased network overhead during increased frequency of node movement increased node density per area, and optimistic routing suffers from non-optimistic access change for individual nodes. The overall communication throughput of a network may be ... |

 | Mobile Ad Hoc Network (MANET) routing protocols provide routing solutions in mobile wireless networks, without assuming any prior knowledge of topology nor any prediction of future topology. However, the resulting routes suffer from delay and consume precious bandwidth. Perfectly scripted routing could theoretically be optimal, (i.e., introduce no delay and cost no additional bandwidth), but would naturally be very fragile. This thesis explores a merging of these approaches, following a ... |

 | Current inter-Service military networking is inefficient and lacks the desired level of Joint interoperability. Generally, the different Service branches build stove-piped networks that do not allow sharing of resources with the other branches. This approach is taken because the individual networks do not see the benefits of interconnectivity as worth the effort required to build secure, stable, and operationally effective network solutions. The Joint Mobile Network Operations (JMNO) project seeks ... |

 | Ad-hoc networks are distributed, self-organized networks which do not need a fixed infrastructure. Entities in networks of this sort must collaborate to make network services such as routing - functional. In these environments, many algorithms from wired networks cannot be naively adapted without congesting the network. The author's work is focused on the study of the information distribution protocol. Indeed, without application, ad-hoc network technologies are useless. Managing services consists ... |

 | Mobile Ad-Hoc Networks (MANETs) are wireless networks that continually re-organize themselves in response to their environment without the benefit of a pre-existing infrastructure. A MANET consists of a set of mobile participants who must communicate, collaborate, and interact to complete an assigned mission. The challenges of MANETs are to provide wireless, high-capacity, secure, and networked connectivity. Participants must communicate using bandwidth limited wireless links with potential intermittent connectivity, as compared ... |

 | Border Gateway Protocol (BGP) is currently the only interdomain routing protocol employed on the internet. It allows tens of thousands of Autonomous Systems (ASes) to exchange routing information while implementing economic and organizational policies. However, conflicting policies between ASes can cause routing instability and/or unpredictable routing solutions. A system of routers is robust if routing tables always converge predictably, despite router and link failures. We pursue an approach to guarantee ... |

 | Titanium is a candidate as a structural material for all new tactical and armored ground vehicles, because of its high strength-to-weight ratio, excellent corrosion resistance, and inherent ballistic resistance. However, titanium as a structural material is much less mature than both steel and aluminum alloys, especially in the area of joining. While welding is the typical joining method for titanium, vacuum brazing is an option in areas that are difficult ... |

 | We formulate and solve aircraft-routing problems that arise when planning missions for military aircraft that are subject to ground-based threats such as surface-to-air missiles. We use a constrained-shortest path (CSP) model that discretizes the relevant airspace into a grid of vertices representing potential waypoints, and connects vertices with directed edges to represent potential flight segments. The model is flexible: It can route any type of manned or unmanned aircraft; it ... |

 | Military communications has always been an important factor in military victory and will surely play an important part in future combat. In modern warfare, military units are usually deployed without existing network infrastructure. The IP routing protocol, designed for hierarchical networks cannot easily be applied in military networks due to the dynamic topology expected in military environments. Mobile ad-hoc networks (MANETs) represent an appropriate network for small military networks. But, ... |
