Slotted Aloha provides a simple way for accommodating the massive access of Machine-to-
Machine (M2M) communications. Yet, the delay performance of slotted Aloha has long been …

We propose FRASA, Feedback Retransmission Approximation for Slotted ALOHA, to study
the stability region of finite-user slotted ALOHA under collision channel. With FRASA, we …

The performance of the ALOHA and CSMA protocols is evaluated within a bounded ad hoc
network. Our network model comprises packets being distributed in finite space and time …

In this paper, we propose an analytical approach for evaluating the performance of finite-
user slotted Aloha in wireless networks with multiple packet reception and random traffic. We …

This paper provides definite results about the access delay of slotted Aloha with exponential
back-off, an infinite number of stages, and queues in saturation. The analysis is performed …

Renewed interest in ALOHA-based Medium Access Control (MAC) protocols stems from
their proposed applications to wireless ad hoc and sensor networks that require distributed …

Given a mobile terminal transmitting a message to some receiver, the level at the receiver
will be affected by path loss and by fading phenomena. Transmissions from different …

Stability region of random access wireless networks is known for only simple network
scenarios. The main problem in this respect is due to interaction among queues. When …

We consider a wireless network of static nodes where each transmitter-receiver pair
employs slotted Aloha, electing to transmit with a common contention probability p, and we …

We present a novel upper bound on the Ergodic Rate Density (ERD) of ALOHA wireless ad-
hoc networks. Our analysis uses a proper model of the physical layer together with an …
