In this paper we formulate a general model of the capacity of single-hop slotted ALOHA
networks. We find that the capacity can be expressed as a function of the nodal degree (ie …

In this paper we investigate the capacity of networks with a regular structure operating under
the slotted ALOHA access protocol. We first consider circular (loop) and linear (bus) …

In this paper two possible policies are investigated for realizing an arbitrary traffic matrix in a
Slotted ALOHA broadcast packet radio network: full connectivity and limited transmission …

A simulation model is developed to compare the performance of mobile slotted ALOHA
networks with linear topology (such as the communications from vehicles to base stations in …

The role played by the number of interferers and the modulation choice in the performance
of slotted Aloha networks with Rayleigh fading is investigated and discussed; the case of …

We analyze the maximum throughputs of slotted-ALOHA-based multihop ad hoc networks
with and without capture, by considering the degree (number of neighbors) of each node …

A general analytical model is proposed to evaluate the performance of a mobile slotted
ALOHA network. Near-far effects are incorporated in the model (in an approximate way) by …

The sum rate performance of random-access networks crucially depends on the access
protocol and receiver structure. Despite extensive studies, how to characterize the maximum …

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 …

Fading channels may improve the capacity of slottedALOHA networks. Rayleigh fading and
spatially distributed packet transmitters diminish mutual packet interference and thus reduce …
