Path Loss Exponent Estimation in Large Wireless Networks Sunil Srinivasa and Martin Haenggi Department of Electrical Engineering University of Notre Dame Notre Dame, IN 46556, USA Email: {ssriniv1, mhaenggi}@nd.edu Abstract—In wireless channels, the path loss exponent (PLE)...
Then by using the proposed path loss model, link budget analysis is performed. From the analysis, it is concluded that the proposed path loss model closely approximates to Stanford University Interim model with path loss exponent value of 3.45....
Normally, algorithms based on RSS measurements need to know, or be able to estimate, channel parameters (such as path-loss exponent and transmission power). However, these parameters may be unknown and difficult to estimate for each anchor node. View chapterExplore book Routing and Data Diffusion...
path loss reduces SNR, it limits either the data rate or the signal range of a given communication system. Moreover, since the path loss exponent determines how quickly the signal power falls off with respect to distance, wireless channels with small path loss exponents will typically have ...
Additionally, the path loss exponent, a measure of how that energy attenuates with distance, is important to establishing range and gain criteria. ... JM Cramer,RA Scholtz,MZ Win - Wireless Communications & Networking Conference 被引量: 77发表: 1999年 Biological fluid sampling apparatus A sampli...
the path loss exponent. The value of p depends upon the current propagation situation. In buildings with a lot of furniture p = 2.4 is used, whereas in empty halls p = 2.0 is suggested. The function f yields the loss (in dB) which is caused by a diffraction. All diffraction losses...

The relation between energy and distance can be written as: E ≈ dα, where E is the energy, d is the distance, and α is the attenuation factor or path-loss exponent. The value of α depends on the transmission medium (α ⩾ 2) [98], e.g., α = 2 in the free-space ...
