    ABSTRACT: There have been many studies in recent years reporting the performance and survivability of mobile ad-hoc networks (MANETs). These studies invariably consider the network as covering a relatively small geographic area. However, in many crises, such as may occur during disaster relief and military operations, a wide geographic area may require network coverage. In these circumstances, the infrastructure free mobile wireless communications features of MANETs may be critical in forming a satisfactory network. Given transmission range limitations within current MANET proposals, it is likely that providing network coverage to a wide geographic area would be problematic. This paper presents the results of a study on clustering in the spatial distribution of communication nodes. A realistic environment (e.g. topography and organisational limitations) and operating procedures are introduced through the use of the results of war games. The spatial distribution of nodes is used as the basis for MANET internetwork topology generation.

    ABSTRACT: Mobility strongly influences the results of mobile ad-hoc network (MANET) simulations. The MANET research community requires mobility models that exhibit characteristics of real networks. In this article, we present preliminary results of a case study based on a war game simulation exercise used for military training and planning purposes. Within the exercise, a wide area network is formed by the interconnection of MANETs, where each MANET is defined as a cluster of network-enabled military platforms and/or troops. Our results show that many assumptions of random mobility models, often used in the literature, do not hold in military MANETs. In particular, a military MANET is heterogeneous comprising mobile nodes of disparate communications capabilities and maneuverability, and is governed by military doctrine plus some randomness. We anticipate these findings will illuminate important characteristics of real MANETs and lead to the construction of improved mobility models.
