Exploring the potential for free-space-optical (FSO) communication in the context of very-high-speed mobile ad-hoc and opportunistic networking by developing an experimental FSO-MANET with basic building blocks such as spherical structures covered with inexpensive FSO transceivers. Developing and validating necessary NS-2 enhancements for FSO propagation and channel model, 3-D obstacle presence, node mobility generators, and designing experiments for comparison of FSO and RF throughput.
Theoretically developing and experimentally demonstrating localization techniques based on the directionality of Free Space Optical (FSO) communication. Investigating novel optoelectronic components and localization algorithms to improve the localization in MANETs to very large scales.
Designing an auto alignment circuitry and MAC protocol for efficient usage of multi-channel spatially-divided medium for multi-element optical transceivers. The goal is to achieve mobility of nodes while maintaining optical connectivity via automatic hand-off of logical flows between physical transceivers.
Investigating cross-layer buffering designs that can remedy the severely reduced throughput problem present in multi-transceiver highly-directional FSO structures through both simulation and prototyping. With our approach to cross-layer buffering schemes for multi-element FSO structures, per-node throughput is significantly increased and TCP is not affected as severely.
