Maximizing Throughput of Finite Population Slotted Aloha

We consider finite population slotted ALOHA where each of n terminals ma.y ha.ve its own transmission proba.bility Pi. Given the traffic load .A, throughput is maximized via. a constrained optimization problem. The resulu; of Abramson (1985) are obtained as special case. .

Stability of slotted ALOHA with spatial diversity

We consider the problem of stability of slotted ALOHA for a system consisting of N users communicating with a common receiver, which employs spatial diversity to receive multiple transmissions simultaneuosly. We introduce a general packet reception model to incorporate multiple packet receptions since the collision channel model is no longer valid in such a scenario. We characterize the stabili...

User registration in broadband slotted Aloha networks

This paper proposes an algorithm for user terminals in broadband slotted Aloha networks to jointly succeed in time synchronization, power adjustment, and registration to the network control center. The performance is analyzed considering nonnegligible initial time uncertainty, nonnegligible power uncertainty, and minimizing cochannel interference as well as binary feedback from the central rece...

Finite 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...
