Efficient Broadcasting in Manets Using Directional Antennas

Broadcast has been widely used in mobile ad hoc networks (MANETs) as a communication means to disseminate information to all reachable nodes. However, the conventional broadcast scheme that broadcast packets omni directionally suffers from several drawbacks: excessive amount of redundant traffic, exaggerated interference/contention among neighboring nodes, and limited coverage (as a result of c...

Electromagnetic Interference Problems Between Power Lines and Metal Pipelines

Electromagnetic interference and cochlear implants.

This paper reviews the most common sources of electromagnetic interference (EMI) with cochlear implants (CI). Particular attention will be given to the description of the mechanisms of electromagnetic interaction with CI; main disturbances caused to CI; relevant scientific investigations; and existing requirements and tests for electromagnetic compatibility (EMC) immunity applicable to CI.

Measurement and Computational Modeling of Radio-Frequency Electromagnetic Power Density Around GSM Base Transceiver Station Antennas

Evaluating the power densities emitted by GSM1800 and GSM900 BTS antennas isconducted via two methods. Measurements are carried out in half a square meter grids around twoantennas. CST Microwave STUDIO software is employed to estimate the power densities in order fordetailed antenna and tower modeling and simulation of power density. Finally, measurements obtainedfrom computational and experime...
