An Empirical Interference Modeling for Link Reliability Assessment in Wireless Networks(Abstract—In recent years, it has been widely believed in the community that the link reliability is strongly related to received signal strength indicator (RSSI) [or signal-to-interference-plus-noise
ratio (SINR)] and external interference makes it unpredictable,which is different from the previous nderstanding that there is no tight relationship between the link reliability and RSSI (or
SINR), but multipath fading causes the unpredictability. However,both cannot fully explain why the unpredictability appears in the link state. In this aper, we unravel the following questions: 1)
What causes frame losses that are directly related to intermediate
link states? 2) Is RSSI or SINR a right criterion to representthe link reliability? 3) Is there a better easure to assess the link reliability? We fi rst confi gured a testbed for performing a real measurement study to identify the causes of frame losses,
and observed that link reliability depends on an intraframe SINR

CurveLab-2.1.2
CurveLab is a collection of Matlab and C++ programs for the Fast Discrete Curvelet
Transform in two and three dimensions.
For the 2d curvelet transform, the software package includes two distinct implementations:
the wrapping-based transform and the transform using unequally-spaced fast Fourier trans-
form (USFFT). Both variants are based on the Curvelet transform as described in ‘New
Tight Frames of Curvelets and Optimal Representations of Objects with Piecewise C2Sin-
gularities’, Comm. Pure Appl. Math. 57 (2004) 219-266. The implementation is also
discussed in detail in ‘Fast Discrete Curvelet Transforms’, Multiscale Model. Simul. 5
(2006), no. 3, 861-899. We advise users to become familiar with these references.
The two implementations diff er by the choice of spatial grid used to translate curvelets at
each scale and angle.(CurveLab is a collection of Matlab and C++ programs for the Fast Discrete Curvelet Transform in two and three dimensions.
