Abstract This thesis presents a method for dyamically setting 802.11 wireless LAN waveforms and transmission power levels based on the wireless channel's signal to noise ratio. Simulation models were developed to study the performance of our media access control (MAC) protocol, SNR-WPA (Signal to Noise Ratio-Waveform Power Adaptation), and compare the performance to a baseline wireless LAN MAC. SNR-WPA method is shown to increase the throughput and range while decreasing the packet delay for...

Abstract The network technology employed in today's military tactical environment is largely based on commercial network technologies. These commercial technologies are designed to operate in a stable environment. However, many military situations arise that demand highly mobile networks. Communications on the move, continuity of operations when a critical node goes down, and instant communcations in areas lacking a communications infrastructure are just a few examples of situations requiring...

Abstract Wireless Mesh Networks (WMNs) could feasibly be used as an organization's secondary backup network due to the properties of WMNs, such as dynamic self-organization, self-configuration, self-healing, decentralized management, and inexpensive implementation. This backup network could be helpful in allowing an organization's business to continue in case of an extended main network outage. This thesis research involved the study and implementation of WMNs to evaluate the feasibility of...

Abstract The goal of this project is to investigate techniques to optimize the datagram routing from a correspondent node to a mobile node in IP networks when mobility is supported. Without Route Optimization, all datagrams destined to a mobile node are routed through that mobile node's home agent, whch then tunnels each datagram to the mobile node's current location. The protocol extensions described here provide a means for correspondent nodes that implement them to cache the binding of a mobile...
