On the Minimum Average Age of Information in IRSA for Grant-Free mMTC
IEEE Journal on Selected Areas in Communications, 2021We consider the optimal design of the frame-based irregular repetition slotted ALOHA (IRSA) protocol for minimizing the average age of information (AAoI) in grant-free massive machine-type communications (mMTC). To this end, we first characterize the AAoI as a function of the number of user elements (UEs), the frame duration, and the repetition ...

IRSA-based Unsourced Random Access over Gaussian Channel
2023 12th International Symposium on Topics in Coding (ISTC), 2023Grant-free massive access schemes based on irregular repetition slotted ALOHA (IRSA) are investigated as an option for unsourced random access over the Gaussian multiple access channel. The goal is to carry out a performance analysis over a noisy channel, seeking for achievable limits on packet loss probability and energy efficiency.

Irregular Repetition Slotted ALOHA with Priority (P-IRSA)
2016 IEEE 83rd Vehicular Technology Conference (VTC Spring), 2016In this paper, a random access with priority protocol named irregular repetition slotted ALOHA with priority (PIRSA) is introduced. By optimizing the packets repetition and using successive interference cancellation (SIC), irregular repetition slotted ALOHA (IRSA) has achieved a high throughput. Contention resolution diversity slotted ALOHA with access

Detecting the Number of Active Users in IRSA Access Protocols
2018 IEEE 29th Annual International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC), 2018We develop a maximum a posteriori detector for the number of unrecovered users in coded random access systems based on the irregular repeat slotted Aloha (IRSA) protocol, where each user transmits in random slots multiple packet replicas whose number (known as the user degree) is drawn according to a given probability mass function and where successive

AUV IRSAS for submarine hydrothermal deposits exploration
2016 IEEE/OES Autonomous Underwater Vehicles (AUV), 2016Small AUV “IK-A” equipped with IRSAS was developed for submarine hydrothermal deposits exploration. Observed IRSAS data could acquire the back scatter image and bathymetry. One of the features of the seafloor hydrothermal deposits is the chimney and the mound-like terrain. Back scatter image can distinguish these terrain and other terrains.
