A scalable testbed for emulating wireless Mobile Ad-hoc Networks

Abstract

To support research in wireless mobile networks and mobile ad-hoc network security, the u.s. Army Research Laboratory (ARL) has developed a HWireless Emulation Laboratory" (WEL). A key component of the WEL is a Mobile Ad-hoc Network (MANET) emulation testbed on which algorithms and applications can be subjected to emulated wireless network conditions. The testbed is based on the MANE (Mobile Ad-hoc Network Emulator) software originally developed by the Naval Research Laboratory (NRL). It has since been improved through the incorporation of advanced modeling methods and computing technologies. Important additional features include (1) the integration of the terrain integrated rough earth model (TIREM) propagation model, (2) the use of virtual machine technologies to scale the size of the network, and (3) the inclusion of custom-designed mobility patterns to create a specific dynamic topology ofa MANET under test. Currently the WEL testbed can emulate a 101-node MANET and, through the use of virtualization technologies, will scale well beyond that number. This paper discusses the current capabilities ofARL's WEL for conducting empirical evaluation and demonstration of MANET technologies and concludes with planned future enhancements. I.

Mobile Ad Hoc Network emulation environment

“…As the need for more diverse and higher fidelity lower layers and additional capabilities grew, NRL developed the Mobile Ad-hoc Network Emulator (MANE) system [5]. Subsequently, NRL, ARL, CENGEN and other developers have enhanced MANE to provide a larger-scale, higher fidelity emulation system capable of supporting arbitrary hosts in a "plug-and-play" fashion through use of centralized packet distribution processor(s).…”

Performance Requirements of Tools and Methods for Specifying Network Communication Scenarios Using the Real-Time Application Representative Version 1.0

“…If the format of "field names = values" is accidentally used, then the tool will process only the left side of the equal character (=). For example, if the expression, hostA, host [1][2][3], is entered into the entry field of the field tag and the Remove button is pressed, the tool will remove four elements from the dictionary, consisting of four item elements and their sub-elements.…”

“…The left side and the right side of the character "=" will follow the rule described in the previous paragraph specifying how to enter multiple values in the entry field of the value tag. For example, if the expression, hostA, host [1][2][3] Adding a field creates a new field item and its corresponding value. Updating a field replaces the content of an existing field with the corresponding value that is being displayed on the screen.…”
