A large-scale ad hoc network testbed was built at Niigata university in November 2004. This testbed has 50 nodes on the building and along streets. Each node is composed of an SH3 processor with embedded Linux and an IEEE 802.11b wireless LAN device. All nodes are connected to the control PC via the control network, which consists of a wired LAN and one-hop wireless links. Several tools to support automatic operations of experiments are provided in the testbed.

This paper aims to present MeshDVNet, a Wireless Mesh Network (WMN)test-bed designed, built, and deployed by the LIP6 laboratory of Université Paris VI. MeshDVNet uses Wireless Mesh Routers (WMR), called MeshDVBox, which have been built using commercial components and open source software. On this platform, routing is performed by MeshDV, our custom routing framework, designed to take full advantage of WMNs' architecture. MeshDVBoxes are able to form a mesh backbone while performing also gateway advertising and natively integrating clients' mobility management.

We investigate the optimal selection of minimum contention window values to achieve proportional fairness in a multirate IEEE 802.11e test-bed. Unlike other approaches, the proposed model accounts for the contention-based nature of 802.11's MAC layer operation and considers the case where stations can have different weights corresponding to different throughput classes. Our test-bed evaluation considers both the long-term throughput achieved by wireless stations and the short-term fairness. When all stations have the same transmission rate, optimality is achieved when a station's throughput is proportional to its weight factor, and the optimal minimum contention windows also maximize the aggregate throughput. When stations have different transmission rates, the optimal minimum contention window for high rate stations is smaller than for low rate stations. Furthermore, we compare proportional fairness with time-based fairness, which can be achieved by adjusting packet sizes so that low and high rate stations have equal successful transmission times, or by adjusting the transmission opportunity (TXOP)limit so that high rate stations transmit multiple back-to-back packets and thus occupy the channel for the same time as low rate stations that transmit a single packet. The test-bed experiments show that when stations have different transmission rates and the same weight, proportional fairness achieves higher performance than the time-based fairness approaches, in terms of both aggregate utility and throughput.

Coordination is expected between mobile terminals, base stations/access points, and spectrum-management servers in cognitive-enabled wireless networks. A testbed for cognitive radio needs to deal with these components to verify low-level configuration protocols and functions on cognitive-radio devices, and to evaluate high-level network protocols and throughputs including new MACs designed for cognitive radio using various applications running on large numbers of nodes. We propose a testbed for an adaptive wireless network under which terminals communicate using both real cognitive-radio devices and those virtually configured. All the stacks from the MAC to the application layer are programmable conforming to the common interface for the MIRAI Cognitive Radio Execution Framework (MIRAI-CREF). The configuration for the physical layer is selected from either a real device or a software-defined pseudo device, which together provide real physical-layer phenomena dependent on device implementations and scalability in the number of nodes. The testbed works with the two physical-layer configurations mixed at the same time. The testbed is flexible enough to configure cognitive-radio device functions and protocols. It is also intended to be used not only by local users but also remote users via the Internet to evaluate protocols and various cognitive features.

BBN Technologies (BBN), under complementary tasks for NASA, designed the High-Throughput Distributed Space-craft Network (HiDSN), developed a laboratory prototype network testbed and, currently, is integrating support for virtual-private-networks (VPN) over such a testbed (SpaceVPN). The ultimate goal of this work is to demonstrate the use and the performance of standard-based IPSec VPNs for secure ground-experimenter access to emulated low-earth orbit sensor satellites in which ground-space-sensor connectivity is achieved using the multi-hop routed space links of HiDSN. As part of this work, BBN has developed and refined an integrated approach to the development of Space-based Radio Protocols. This approach consists of high level quasi-analytic modeling using Mathematica, the use of "Active" Mathematica-based protocol specifications that document and simulate protocols, and the use of Software Defined Radio techniques for software proto-typing, Radio Frequency link emulation and testbed implementation. This paper describes the overall approach used to develop HiDSN for NASA and describes each of the component techniques.

An increasing number of people today depend on the ability to connect to wireless network access points in a variety of situations. While one-hop access points were a suitable solution in the beginning, they suffered from problems such as low coverage area and over-load. One promising solution is the use of wireless mesh networks (WMNs). This allows wireless access points to be placed in a very flexible fashion, so that they can extend wireless coverage into places that do not have easily accessible wired infrastructure. There are existing projects that examine some methods for deploying mesh access networks. For example, the MIT Roofnet project [1] has created a system that can easily add new access points at random, and incorporate them into a large scale mesh. However, we are more interested in a planned mesh network. In such a network, concepts like quality of service will be important, so a robust admission control scheme is necessary. This poster will present a foundational centralized routemanagement system for WMNs. Our scheme is based on the Wireless Distribution System (WDS). Our work has been an extension of the existing implementation of WDS in the MADWiFi driver for Atheros wireless LAN chipsets. We are interested in provisioning quality of service guarantees for planned WMNs being used as access networks, as well as providing fault tolerance. Very few admission control schemes have been proposed so far for WMNs, and most apply to the case of unplanned WMNs, using routing protocols developed for ad hoc networks. Planned WMNs are witnessing an increasing number of deployments across enterprises, universities and cities. These networks will require an effi-

The RFID reader collision problem[4] occurs when a signal from one reader interferes with the signal from other readers. In this paper, we propose a RCF(Reader Collision Free) protocol, a protocol to reduce these reader collisions in the RFID systems. The operation of the RCF protocol is based on RTC/CTS mechanism in IEEE 802.15.4 sensor networks. We verify the proposed RCF protocol using experiment in RFID sensor network.
