There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract:
The objective of the proposed research is to design full integrated magnetic induction (MI)-based Wireless Underground Sensor Networks (WUSNs) to enable reliable and efficient wireless communications in underground oil reservoirs to perform in-situ monitoring of oil reservoirs. This is very crucial for determining the sweet spot of oil and natural gas reserves. Wireless sensor nodes are a promising technology to collect data from oil reservoirs in real time. To this end, we propose contributions in four areas as follows: first, we developed a novel cross-layer communication framework for MI-based networks in dynamically changing underground environments. It combines a joint selection of modulation, channel coding and power control, a transmitter-based CDMA scheme and a geographic forwarding paradigm. Second, we developed a novel magnetic induction (MI)-based localization framework which exploits the unique properties of the MI field to determine the locations of the randomly deployed sensor nodes in oil reservoirs. Third, we proposes an accurate energy model framework of a linear oil sensor network topology that gives feasible sensors' transmission rates and sensor network topology while always guarantees enough energy. Then, we will design, develop and fabricate MI-based sensor nodes. Finally, we will develop a physical MI-based WUSN testbed to validate the performance of the proposed solutions in practical way as we are going to implement the proposed solutions in the designed MI-based sensor nodes.
