Age of Information Under Frame Slotted ALOHA-Based Status Updating Protocol

Dynamic Grouping Frame-slotted Aloha

Passive UHF RFID systems using Dynamic Frame-Slotted ALOHA (DFSA) adjust the frame size according to the number of tags, but frame size N is equals to 2^Q and cannot be adjusted exactly to the number of tags to be identified. In this paper, we proposed a new Aloha based anti-collision algorithm which divides the tags and adjusts the frame sizes in such a manner as to always keep the system effi...

A Improved Frame Slotted Aloha Protocol with Early End in Mobile RFID Systems

Frame slotted ALOHA (FSA) protocol is a classic tag anti-collision protocol. Similar to most existing anti-collision protocols, The FSA initially aims at tag identification of static scenarios, that is, all tags keep still during the tag identification process. However, in many real scenarios, tags generally move along a fixed path in the reader coverage area, that is, tags stay the coverage ar...

Performance Analysis of RFID Framed Slotted Aloha Anti-Collision Protocol

In this paper, we develop a novel mathematical model to estimate the probability distribution function of the number of tags discovered after a certain number of interrogation rounds. In addition, the pdfs of the number of rounds needed to discover all the tags are also calculated. The estimation of such pdfs will be helpful in estimating the number of interrogation rounds and the optimal param...

Optimal frame size analysis for framed slotted ALOHA based RFID networks

We offer an analytical solution for the optimal frame size of the non-muting version of the Basic Frame Slotted ALOHA collision resolution protocol for RFID networks. Previous investigations of RFID frame size have been empirical and have not yielded a general result. Our theoretical analysis provides a generalized result. Our solution can be used to determine the optimal frame size for any giv...
