Improved Object Localization Using Accurate Distance Estimation in Wireless Multimedia Sensor Networks - Fig 4

<p>(a) Referential frame for estimating location of an object. (b) Case where object distance from the sink node is greater as compared to monitoring WMSN node <i>C</i>_{<i>D</i>,<i>O</i>} > <i>B</i>_{<i>D</i>,<i>N</i>}. (c) Case where object distance from the sink node is smaller as compared to monitoring WMSN node <i>C</i>_{<i>D</i>,<i>O</i>} < <i>B</i>_{<i>D</i>,<i>N</i>}. (d) Case where object distance from the sink node is equal to the monitoring WMSN node <i>C</i>_{<i>D</i>,<i>O</i>} = = <i>B</i>_{<i>D</i>,<i>N</i>}.
