Enabling seamless communication over several IoT messaging protocols in OpenFlow network
The most prominent protocols for data transfer in internet of things (IoT) are
message queuing telemetry transport (MQTT) and constrained application
protocol (CoAP). The existing clients from both sides are unable to
communicate directly because…

Efficient SOVA decoding and enhanced early termination mechanism based on new attenuation factors
This paper proposes two attenuation factors (AF’s) to improve the performance of the soft-output Viterbi algorithm (SOVA) as well as to enhance the early termination mechanism in turbo decoding. The mean
square difference between the systematic…

Effects of humidity on sand and dust storm attenuation predictions based on 14 GHz measurement
Several models were proposed to predict the attenuation of microwave signals
due to sand and dust storms. Those models were developed based on
theoretical assumptions like Rayleigh approximation, Mie equations or
numerical methods. This paper…

Earprint recognition using deep learning technique
Earprint has interestingly been considered for recognition systems. It refers
to the shape of ear, where each person has a unique shape of earprint. It is a
strong biometric pattern and it can effectively be used for authentications. In
this…
