Abstract
In 3D wireless sensor networks, many connection-based information brokerage schemes, which use the node connection information rather than the geographic location in- formation, have been proposed. Each one, however, either cannot guarantee data retrieval or incurs a considerable amount of replication overhead costs, making these schemes hard to use in actual practice. In this thesis, a connection-based infor- mation brokerage schemes, RGIB3D, are proposed for 3D wireless sensor networks. RGIB3D are shown, using theoretical analysis, to be retrieval-guaranteed, and shown, with simulations, to have short retrieval latencies while ensuring moderate replication overhead costs in 3D wireless sensor networks.
