We consider a Machine-to-Machine (M2M) network where a large number of user nodes
(STAs) communicate with a Data Collector (DC). We consider the case where all the user …

To solve the conflict when multi-user packets are transmitted in a shared wireless link, a
novel frameless slotted-ALOHA protocol is proposed. Signature codes are used to help the …

The throughput performance of a mobile S-ALOHA network can be improved considering
the capture phenomenon, which also depends on the spatial distribution of the mobiles …

This letter presents a mean value analysis of the age of information for slotted ALOHA, a
widely-used medium access control protocol in communication networks. Unlike previous …

Stochastic geometry proves to be a powerful tool for modeling dense wireless networks
adopting random MAC protocols such as ALOHA and CSMA. The main strength of this …

As one of the most representative random-access schemes, slotted Aloha has been adopted
in various wireless communication networks. A multi-cell Aloha network may easily become …

Almost 40 years have passed since the creation of ALOHAnet [1], the first packet-based
wireless computer network created in 1970 at the University of Hawaii. Since then, advances …

The authors investigate the maximum throughput that can be supported between a pair of
nodes in a multihop packet radio network using slotted ALOHA. The optimization problem …

In this thesis the performance of the ALOHA and CSMA MAC protocols are analyzed in
spatially distributed wireless networks. The main measurement metric used is probability of …

Wireless random access protocols are attracting a revived research interest as a simple yet
effective solution for machine-type communications. In the quest to improve reliability and …
