Approved for public release, distribution is unlimited / On the modern battlefield, successful and fast communications is a critical issue. So the need for transmitting information in larger amounts through a military high-speed network increases. Thus the military is seeking viable and effective solutions that may fulfill these requirements in an operational environment. This thesis develops a prototype system based on appropriate low-cost software and hardware solutions. This system is able to detect, analyze and process wireless 802.11g signals. The evaluation of the newly designed system proved that it is effective up to distances of about 400 m with a low packet error rate and could be a useful tool for detecting wireless 802.11g networks. After evaluating the system, it was used for capturing wireless signals so that we would determine the effective transmission range and the data throughput of an 802.11g network. We determined that such a wireless network could be used in military operations because it offers high data rates up to 200 m, while it maintains a connection of the wireless clients for distances up to 400 m. In addition, the performance data collected can be used as guidelines for estimating the expected performance in an operational situation and can provide useful information for successful planning. / Lieutenant, Hellenic Navy

Approved for public release, distribution unlimited / Since wireless technology has been used in Local Area Networks (LAN), our networks are easier to build and are more scalable and mobile than legacy structures. While providing these functionalities, Wireless LAN (WLAN)'s have some security vulnerabilities that should be addressed. Failing to examine the security risks of WLAN technology and take the necessary countermeasures may result in unauthorized entry into the legacy local area networks and other attacks. A secure connection to an intranet, which holds critical data and applications, must be the utmost consideration in the effort to protect critical resources. This thesis builds an open-source test-bed for evaluating WLAN security protocols. Moreover, it investigates the suitability of the IEEE 802.1X standard to provide the required security framework to WLANs. This research determines that the IEEE 802.1X could enhance the security level in authentication and privacy by the enabling rekeying process, but would not prevent Denial of Service attacks via unauthenticated management frames. / Turkish Navy author.

Media access control (MAC) protocols play a vital role in determining the performance of wireless local area networks (WLANs). While a variety of MAC protocols have been proposed recently for wireless LANs, the problem of efficient bandwidth utilization, higher throughput, lower mean delay, and fairness has not been fully solved yet. For example, IEEE 802.11 protocol does not perform well and the bandwidth utilization drops below 50% of the total bandwidth under heavy traffic load conditions.Therefore, in order to address these problems of WLANs under heavy traffic load, this thesis proposes a new scheme named Buffer MAC. We analyze the performance of Buffer MAC by using a number of simulation experiments based on ns-2 network simulator. Results show that the proposed Buffer MAC protocol not only improves bandwidth utilization of WLANs but also improves average packet delay, throughput and fairness performance under heavy traffic load conditions.This thesis also contains an exhaustive and comparative study of the new MAC protocol and the original IEEE 802.11 protocol. Some implementation aspects of Buffer MAC protocol are also discussed.
