Recently, many variants of Slotted ALOHA (S-ALOHA) have been proposed to solve a
problem of performance degradation in wireless networks with long propagation delay …

In a wireless network with large propagation delay S-ALOHA (Slotted ALOHA) requires large
guard time which causes lower normalized throughput. To reduce the large guard time in the …

Mobile ad hoc networks (MANETs) with Aloha MAC protocol (A-MANETs) represent a class
of important and attractive networks. This paper studies the Rate of Successful …

In recent years, connection-based slotted-Aloha (CS-Aloha) has been proposed to improve
the performance of random access networks. In this protocol, each node attempts to send a …

Prior investigations on the Aloha network have primarily focused on its system throughput.
Good system throughput, however, does not automatically translate to good delay …

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 …

A new adaptive transmission protocol is introduced to improve the performance of slotted
ALOHA. Nodes use known periodic schedules as base policies with which they …

For future machine-type communication systems, the frame duration will shorten because
the sensor data size is small and the PHY rate gets higher. The contention interval caused …

In this paper, we study the throughput and delay performances of the slotted Aloha with
batch service, which has wide applications in random access networks. Different from the …

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 …
