RRCpacketSniffer is an android application which can be used for capturing tcp udp and icmp data packets and resulting RRC state transitions, simultaneously.
The application is working implementation of the tool discussed in this research paper Android phone based appraisal of app behavior on cell networks
Quantifying an application’s signaling efficiency requires information about:
- The data packets that were exchanged.
- The RRC state transitions that took place..
Unlike the existing applications and tools, this application neither requires any special hardware, nor retrieves RRC state in an offline manner using a simulator. The functionality of the tool is split into two parts, the Packet Sniffer and the RRC State Logger.
The packet sniffer uses C_packetCapture a binary executable of libpcap, built using libpcap source code and Android NDK. The executable is launched in a shell with superuser privileges. The packet sniffer enables us to capture all uplink and downlink packets associated with a network interface, and stores the packet timestamp and header information corresponding to IP, UDP, TCP, and ICMP protocols, in a log.text file. ###RRC State Logger For Retrieving RRC States, we adopt a novel approach to find and record the actual RRC state of the device at any given instant. Android Secret codes are required to switch to RRC service mode. Currently we have secret codes for limited samsung devices, though a wide variety of secret codes are available for different manufacturers.
The detailed explaination of calucalting an application's signalling efficiency from the data collected is described in this paper Android phone based appraisal of app behavior on cell networks
The application currently supports all major Samsung devices ranging from Galaxy S to Galaxy S5 and requires root permission for full functionality. We are working to extend this to other device brands as well.
