1	Building a simulation toolkit for wireless mesh clusters and evaluating the suitability of different families of ad hoc protocols for the Tactical Network Topology Karapetsas, Konstantinos 03 1900 (has links) Approved for public release, distribution is unlimited / Wireless mesh networking has emerged as the successor of the traditional ad hoc networks. New technological advances, the standardization of protocols and interfaces and the maturity of key components have made it possible for current mesh research groups to set goals that are really close to the world's expectations. The objective of this research is to design and implement a simulation toolkit for wireless mesh clusters that can be used as an additional performance evaluation technique for the Tactical Network Topology program of Naval Postgraduate School. This toolkit is implemented in the OPNET simulation environment and it incorporates various nodes running different ad hoc routing protocols. Furthermore, the investigation of a suitable combination of protocols for the Tactical Network Topology is achieved by creating scenarios and running a number of simulations using the mesh toolkit. / Captain, Hellenic Air Force Computer simulation Simulation methods IEEE 80216 (Standard) Ad hoc networking MANET Wireless mesh networks OLSR DSR ADDV Tactical network topology OPNET IEEE 802.16 DOCSIS Network modeling and simulation
2	Analysis of hardware requirements for airborne tactical mesh networking nodes / An analysis of tactical mesh networking hardware requirements for airborne mobile nodes Milicic, Gregory J. 03 1900 (has links) Approved for public release, distribution is unlimited / Wireless mesh mobile ad hoc networks (MANETs) provide the military with the opportunity to spread information superiority to the tactical battlespace in support of network-centric warfare (NCW). These mesh networks provide the tactical networking framework for providing improved situational awareness through ubiquitous sharing of information including remote sensor and targeting data. The Naval Postgraduate School's Tactical Network Topology (TNT) project sponsored by US Special Operations Command seeks to adapt commercial off the shelf (COTS) information technology for use in military operational environments. These TNT experiments rely on a variety of airborne nodes including tethered balloon and UAVs such as the Tern to provide reachback from nodes on the ground to the Tactical Operations Center (TOC) as well as to simulate the information and traffic streams expected from UAVs conducting surveillance missions and fixed persistent sensor nodes. Airborne mesh nodes have unique requirements that can be implemented with COTS technology including single board computers and compact flash. / Lieutenant, United States Navy Netcentric computing United States IEEE 80211 (Standard) Global Information Grid Command and control systems Wireless mesh networking Ad hoc networking IEEE 802.11 Global information grid MANET Wireless OLSR Sensor networks Tactical network topology Single board computer PC/104 Tern UAV
3	An analysis of network and sensor performance within IEEE 802.x wireless MESH networks in the Tactical Network Topology (TNT) Davis, Joseph A., Sr. 03 1900 (has links) Approved for public release, distribution is unlimited / The objective of this research is to analyze the network performance and sensor functionality, efficacy and usability of IEEE 802.x wireless MESH networks within a DoD Tactical network environment. Multiple sensor configurations operating with wireless MESH network technologies will be researched and analyzed for performance in expeditionary environment situations. Specifically, this thesis will attempt establish the foundation for the development of wireless MESH "network health" models by examining the performance of sensors operating within a MESH network and define which network performance metrics equate to good quality of service. This research will experiment with different application, sensor, and network configurations of currently available COTS components, such as, voice, video and data hardware. This thesis will lay the groundwork for wireless network MESH predictability, which will enable the optimal use of sensors within a tactical network environment. / Lieutenant Commander, United States Navy IEEE 80211 (Standard) Wireless communication systems Global Information Grid Sensor networks Wireless MESH networking Ad hoc networking IEEE 802.11 IEEE 802.16 IEEE 802.15.4 Global information grid Wireless MANET Sensor networks Tactical network topology
4	Collaborative applications used in a wireless environment at sea for use in Coast Guard Law Enforcement and Homeland Security missions Klopson, Jadon E., Burdian, Stephen V. 03 1900 (has links) Approved for public release, distribution is unlimited / This thesis analyzes the potential impact of incorporating wireless technologies, specifically an 802.11 mesh layer architecture and 802.16 Orthogonal Frequency Division Multiplexing, in order to effectively and more efficiently transmit data and create a symbiotic operational picture between Coast Guard Cutters, their boarding teams, Coast Guard Operation Centers, and various external agencies. Two distinct collaborative software programs, Groove Virtual Office and the Naval Postgraduate School's Situational Awareness Agent, are utilized over the Tactical Mesh and OFDM network configurations to improve the Common Operating Picture of involved units within a marine environment to evaluate their potential impact for the Coast Guard. This is being done to increase the effectiveness and efficiency of Coast Guard units while they carry out their Law Enforcement and Homeland Security Missions. Through multiple field experiments, including Tactical Network Topology and nuclear component sensing with Lawrence Livermore National Laboratory, we utilize commercial off the shelf (COTS) equipment and software to evaluate their impact on these missions. / Lieutenant Commander, United States Coast Guard / Lieutenant, United States Coast Guard IEEE 80211 (Standard) Wireless communication systems United States Mesh Groove virtual office Situational awareness multi agent system Internet Nodes Wireless IEEE 802.11 IEEE 802.16 Peer to peer relationships Collaborative environment Common operating picture Tactical network topology Lawrence Livermore National Laboratory Tactical satellite Deepwater
