existing system of sniffer for detecting lost mobiles
Abstract
The cell phone though the mobile communication system is proved to be an advantageous method of communication over wired communication, there is another problem that is the mobile phones get lost or get misplaced. The losses are increasing day by day and there has been very little effort that has been done to obtain the lost mobile phone. The main scope for this paper is The proposal for the detection for the lost mobile phones. Every day over thousand of mobile phones get misplaced and lost, though an effective way for the blocking of the lost mobile to prevent unwanted user has been done by the manufacturers of the mobile by usage of International Mobile Equipment Identifier (IMEI) has been done but however there has been no development or very little progress in this area to find the misplaced mobile phones.
Introduction
The main scope of this research is to detect the lost mobiles. Each and every day thousands of mobiles get misplaced or lost, though effective way for the blocking of the lost mobile to prevent unauthorized person from making and receiving the calls has been done by the manufacturers of the mobile with the help of International Mobile Equipment Identifier (IMEI) has been done but however there has been no development or very little progress for the detection of the misplaced mobile phone. The GSM MoU s IMEI (International Mobile Equipment Identity) numbering system is a 15 digit unique code that is used to identify the GSM/DCS/PCS phone. When a phone is switched on, this unique IMEI number is transmitted and checked against a data base of black listed or grey listed phones in the network s EIR (Equipment ID Register). This EIR determines whether the phone can log on to the network to make and receive calls. To know the IMEI number the *#06# has to be pressed; the number will be displayed
in the LCD screen. For the detection of lost mobile SNIFFER plays a vital role .The sniffer device has to be designed precisely and size should be
reduced for easy mobility for the purpose of detection .The device can be called as a mobile Base station that includes Sniffer Base station, unidirectional antenna, tracking software. The sniffer is a small base station that includes transceiver section. It should operate at a frequency which is much different from the frequency of the current cell in which the operation of detection is being carried out. The directional antenna is an important device that is to be designed and used as it plays a major role. There are certain boundary conditions that have to be qualified for the identification of lost mobile like the power of the mobile should be good enough, the mobile phone should not be in the shadow region but however this method using modern technologies and devices. This research seems to be a bit costlier for initial setup but the cost is gradually reduced when effectively and efficiently utilized for the purpose of detection
