Introduction• The main scope is to detect the lost mobiles•For the detection of lost mobile SNIFFERplays a vital role•The sniffer device has to be designed preciselyand size should be reduced for easy mobility forthe purpose of detection
What a SNIFFER is?The sniffer is basically a transceiver thatworks in the frequency which is in thespecial unused range that is operated by theservice provided or it can designed tooperate at a frequency that is of muchdifferent frequency than the one that isbeing used
SOFTWARE FOR THE TRACKING• The software part plays a major role in thetracking of the lost mobile phone.•The mobile phone that is lost has certainIMEI number that is embedded in the chip•The software that is to be designed in such away that the software has the input as theIMEI number of the lost mobile phone
•After getting the input of the lost mobilephones IMEI number it checks the comportfor getting the information•It checks whether it obtains any signalinginformation from the lost device that mightrespond to the signal sent by the sniffer
Working of sniffersThe working of sniffers is of two phases:Before Sniffer increases the frequencyAfter Sniffer increases the frequency
Before Sniffer increases the frequency•By default Mobile devices alwaysconnects to the BTS(Base Station) andMSC(Mobile Switching Center).•Now the sniffer increases thefrequency and amplitude.•As shown in the figure in the nextslide
After Sniffer increases the frequency•So, only the particular user with the IMEI willbe connected to the particular frequency.•The other mobile devices of the surroundingswill not be connected.•As shown in the figure in the next slide
From the above figure we have clearly observed thetracing of the lost mobile.We have identified the lost mobile using IMEI. But,The location where it is present can be known byseeing at the output of the software.Which depicts and retrieves the details of the lostmobile as shown in the next slides.
CONCLUSION•The idea of development “Sniffer for thedetection of lost Mobile phones” paves away by means of which the lost mobilephones can be recovered.•Let all of us hope for the advancement ofthe technology in this domain.•Which will be very helpful for each andevery persons who are lost mobiles.
