17. Experiences from the Empirical Evaluation of Two Physical Layers for Node Localization.

Author

Poovendran, Radha, Roy, Sumit, Wang, Cliff, Lymberopoulos, Dimitrios, and Savvides, Andreas

Abstract

Node localization has attracted significant multidisciplinary research effort over the last few years. Despite these efforts, there is still no clear consensus on a particular technology or approach that can be used in a wide variety of environments. While this may be attributed to several reasons including cost, power and computation complexity, many researchers would agree that physical layer issues impose the largest barrier in the wider deployment and use of node localization services.

18. An Empirical Characterization of Radio Signal Strength Variability in 3-D IEEE 802.15.4 Networks Using Monopole Antennas.

Abstract

The wide availability of radio signal strength attenuation information on wireless radios has received considerable attention as a convenient means of deriving positioning information. Although some schemes have been shown to work in some scenarios, many agree that the robustness of such schemes can be easily compromised when low power IEEE 802.15.4 radios are used. Leveraging a recently installed sensor network testbed, we provide a detailed characterization of signal strength properties and link asymmetries for the CC2420 IEEE 802.15.4 compliant radio using a monopole antenna. To quantify the several factors of signal unpredictability due to the hardware, we have collected several thousands of measurements to study the antenna orientation and calibration effects. Our results show that the often overlooked antenna orientation effects are the dominant factor of the signal strength sensitivity, especially in the case of 3-D network deployments. This suggests that the antenna effects need to be carefully considered in signal strength schemes. [ABSTRACT FROM AUTHOR]
