outputdistance?outputDistance.xlsxcsv | Created by Zafar Gilani, sent by email 6/1114/2010. It compares Tri-lateration trilateration (3 landmarks) with mulitlateration (<=3 to 5 landmarks) giving the target hostname, IP address, its actual locationlat/longs, the targets estimated location, landmark hostnames, landmark lat/longs and error between estimated and actual |
Created by Fida, sent by email 6/10/2010. It is a compendium comparing the several of the geolocation methods including:CBG, SOI, TBG, TBG_Updtaed, Apollonius, Triilateration | |
File Sent by Zafar 3.08pm Jun 1 2010. Compares improved trilateration vs CBG trilateration. - There are a total of 174 targets for CBG out of which 131 are those which ignore values that are either "0<error<1" or "NaN". | |
From Zafar by email 6/2/2010 2:06am. So far what I've gathered from doing this: There are so-called "bad" landmark estimate values in target files which causes these s. There is also a portion in the code that deliberately ignores such values (see 1 under "Results, observations and explanation" here). By restricting n to 10 and 4 I've managed to remove those "bad" values for 39 and 14 targets respectively. |
