UNDERWATER COMMUNICATIONS WITH ACOUSTIC STEGANOGRAPHY: RECOVERY ANALYSIS AND MODELING
(Monterey, CA; Naval Postgraduate School, 2021-12)
In the modern warfare environment, communication is a cornerstone of combat competence. However, the increasing threat of communications-denied environments highlights the need for communications systems with low probability ...
MODELING AND ANALYSIS OF MASKED CARRIER CHANNEL ACOUSTIC COMMUNICATION
(Monterey, CA; Naval Postgraduate School, 2021-06)
Legacy Navy communication systems are used for command and control in underwater fighting environments. Adversaries will seek to deny these communication mediums. Additionally, the use of these communication systems may ...
AN EVALUATION OF USING DETERMINISTIC HEURISTICS TO ACCELERATE REINFORCEMENT LEARNING
(Monterey, CA; Naval Postgraduate School, 2018-12)
Neural networks frequently face long training times based on the corpus of data available to them. Reinforcement learning in particular can take a long time to attain satisfactory performance. Recent efforts to incorporate ...
AN IN-DEPTH ANALYSIS OF A MACHINE-LEARNING-BASED NETWORK ROUTING PROTOCOL FOR NETWORKING IN A HIGHLY MOBILE TOPOLOGY
(Monterey, CA; Naval Postgraduate School, 2018-12)
This thesis studies the performance of a machine-learning-based DTN routing protocol, QGeo. QGeo is based on the reinforcement learning model called Q-learning whereby an agent in some context takes an action, gains a ...
SCALING NETWORK TARPITS FOR IPV6
(Monterey, CA; Naval Postgraduate School, 2018-12)
Cyberspace is vital to the application of joint military operations, to the advancement of economic growth, and to the enhancement of day-to-day life. As such, its defense is critical, yet its defense is also difficult, ...
UNDERWATER MASKED CARRIER ACOUSTIC COMMUNICATION: MODELING AND ANALYSIS
(Monterey, CA; Naval Postgraduate School, 2018-06)
As naval warfighting capabilities evolve, the need for innovative communication techniques for tactics and command and control increases. Using Navy sonar systems normally reserved for conventional communication in the ...
Comparative analysis of disruption tolerant network routing simulations in the ONE and ns-3
(Monterey, California: Naval Postgraduate School, 2017-12)
This thesis studies the performance of Disruption Tolerant Networking (DTN) routing protocols, and the effect of simulator selection. Research into the Geo-location Assisted Predictive Routing (GAPR), and GAPR2 protocols ...
Mapping ad hoc communications network of a large number fixed-wing UAV swarm
(Monterey, California: Naval Postgraduate School, 2017-03)
In 2015, a group of Naval Postgraduate School (NPS) professors and students set a record when they flew 50 fixed-wing unmanned aerial vehicles (UAVs) simultaneously as a self-organizing swarm. These vehicles were able to ...
Multipath transport for virtual private networks
(Monterey, California: Naval Postgraduate School, 2017-03)
Virtual Private Networks (VPNs) are designed to use the Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) to establish secure communication tunnels over public Internet. Multipath TCP (MPTCP) extends TCP ...
Application transparent HTTP over a disruption tolerant Smart-Net
(Monterey, California: Naval Postgraduate School, 2014-09)
This research explores methods to increase the performance of HTTP traffic when operating on a network that is prone to disrup-tions. The SmartNet architecture is presented as an open and extensible software framework for ...
