On Frame Asynchronous Coded Slotted ALOHA Analysis of a Reliable and Low Latency Uncoordinated Multiple Access Technique
Recently, a new class of uncoordinated multiple access techniques named coded slotted ALOHA (CSA) has emerged and attracted much interest. CSA is based on the well known slotted ALOHA system. The key innovation of CSA is that users replicate each packet over several slots and that decoding is performed iteratively over a sequence of slots using successive interference cancellation. One of the i...
متن کاملDynamic 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...
متن کاملFinite Length Performance of Random Slotted ALOHA Strategies
Multiple connected devices sharing common wireless resources might create interference if they access the channel simultaneously. Medium access control (MAC) protocols generally regulate the access of the devices to the shared channel to limit signal interference. In particular, irregular repetition slotted ALOHA (IRSA) techniques can achieve high-throughput performance when interference cancel...
متن کاملDelay distributions of slotted ALOHA and CSMA
In this paper, we derive the closed-form delay distributions of slotted ALOHA and nonpersistent carrier sense multiple access (CSMA) protocols under steady state. Three retransmission policies are analyzed. We find that under a binary exponential backoff retransmission policy, finite average delay and finite delay variance can be guaranteed for 2 and 4 3, respectively, where is the channel traf...
متن کاملFinite Length Analysis of Irregular Repetition Slotted ALOHA in the Waterfall Region
A finite length analysis is introduced for irregular repetition slotted ALOHA (IRSA) that enables to accurately estimate its performance in the moderate-to-high packet loss probability regime, i.e., in the so-called waterfall region. The analysis is tailored to the collision channel model, which enables mapping the description of the successive interference cancellation process onto the iterati...
