“…Traditional error control and recovery schemes like FEC, or more generally Error Control Coding (ECC), and Automatic Retransmission reQuest (ARQ) for data communications have been developed for video communication aiming at lossless recovery while signal reconstruction and error concealment techniques are other schemes striving to obtain a close approximation of the original signal as human eyes can tolerate a certain degree of distortion in image and video signals [19]. These design improvements are part of advanced QoS design.…”

5G wireless mobile communication is expected to include a large number of advanced technologies in order to further increase bandwidth, Quality of Service (QoS), improve usability and security, decrease delays and cost of service. Software Defined Radio (SDR) will be the platform for advanced terminals. Our focus is security and especially prevention of Denial of Service (DoS) attacks which we believe will become more common in commercial networks through increasing availability of easy programmable SDRs. We propose a secret version of Adaptive Frequency Hopping, as a possible 5G technology in combination with others, with QoS estimation by means of physical layer parameters. The QoS parameter chosen is Bit Error Rate (BER) and this we use for blacklisting frequencies that we assume are under DoS attack. Our experimental results on BER estimation show this to be a promising approach.

“…PREVIOUS WORK ATM networks, which are prone to channel impairments, need effective channel error resistive mechanisms to be employed. PRASAN error concealment model [11] was developed to provide enhanced security by employing NFD steganography mechanism [12] and reliability to the Video frames transmitted in lossy networks by introducing the concept of inverse polynomial generation based on the principle of bit mapping. PRATM model [13] applied PRASAN error concealment model specific to ATM network congestion management by generating Inverse ATM pairs for high priority ATM packets.…”

To combat channel impairments during transmission of high fidelity audio streams over noisy ATM networks in addition to providing security and high compression to the audio data have been challenging tasks for the researchers in the field. This paper proposes a multi functionality model employed at the transmitting end that provides the advantages of multi level compression, error recovery mechanism and the security for the audio data in ATM networks. The proposed model introduces the Modulo Coefficient Booster Transform (MCBT) that translates the relevant frequency domain coefficients of the audio stream filtered from a human acoustic modeler into strictly increasing / decreasing booster coefficients (employing Coefficient localization, Burrow Wheeler transform and Mathematical Curve tracing). The booster coefficients obtained are fit to corresponding modulo mathematical functions, which are encoded and transmitted after incorporating security and error recovery mechanisms. Employing the PRATM model to provide error recovery for the transmitted data in the noisy channel provides reliability to the data. The proposed transform can be completely invertible (being a function of set lapse time and error deviation threshold) and provides additional security by means of localizations of the functions generated based on hamming distance computations. The model was tested for various bit error rates of high fidelity audio streams simulated in noisy network environments. The PSNRs , security and the overall reliability of the proposed model encourage the model to be preferred for transmissions of audio streams over noisy ATM networks.
