“…This proposed approach is an extension of our approach proposed in [23]. In [23], correctly decodable users remain idle during the next retransmission. However, to further improve wireless channel utility and improve BER and throughput, SHARQ IR is implemented by retransmitting the redundant bits along with the transmission of new bits for correctly decodable users.…”

Multiple Input and Multiple Output is a technology through which data are transmitted over the channel through multiple antennas. However, during its deployment and implementation, some pragmatic issues arise such as interference, multipath fading and noise leading to potential packet losses and consume substantial energy. To address such issues, Hybrid ARQ transmissions provide effective means for error correction, especially in a noisy wireless channel. More often few bits in packets are found to be in error and it is unnecessary to use the entire MIMO channel for retransmission to correct these errors. Hence, this paper proposes a novel approach, i.e., Shared Hybrid ARQ (SHARQ IR) using the piggyback technique in an overloaded MIMO system where the transmitting antennas are more than the receiving antennas. Additionally, the concept of a simple retransmission method is used to transform an overloaded MIMO system into either the critically loaded or under loaded MIMO systems. Simulation results outperform the contemporary approaches through reduced BER and 20% throughput gain. Such improvements have the potential to support energy-efficient transmissions for encouraging green IoT applications.

A new cognitive user emulation attack (CUEA) in a cognitive radio network (CRN), which could be utilized by intruders during spectrum handoff is introduced. The need for more efficient spectrum utilization in our increasingly digitalized society is becoming more important. This has given raise to the variety of new security threats. A safe handoff mechanism that could successfully counter such an attack by introducing a coordinating cognitive user that computes the level of trust of each cognitive user based on its behavioral characteristics is proposed. Malicious users could be effectively identified by the coordinating cognitive user by looking up the trust values. The activity of the proposed mechanism is validated using MATLAB simulation. The simulation executed describes the utilization of the proposed mechanism by correctly identifying the probability of false detection, detection rate, incorrect detection shown as it decreases the data transmission time or increases the transmission rates of primary user's signals.
