Maximum Sum Rate of Slotted Aloha with Successive Interference Cancellation
This is a sequel of our previous work [8] on characterization of maximum sum rate of slotted Aloha networks. By extending the analysis to incorporate the capacity-achieving receiver structure, Successive Interference Cancellation (SIC), this paper aims to identify the rate loss due to random access. Specifically, two representative SIC receivers are considered, i.e, ordered SIC where packets ar...
متن کاملSlotted ALOHA with Capture in a Mobile Radio Environment
In this paper, we consider a slotted ALOHA protocol with capture, in a mobile communication environment, in the presence of Rayleigh fading and log-normal shadowing. The capture probabilities are computed, along with their limit as the number of colliding packets tends to innnity. Some suucient conditions for this limit to be positive, and therefore for the system to achieve a positive stable t...
متن کاملMobile Radio Slotted ALOHA with Capture and Diversity
In this paper, the Slotted ALOHA protocol in a mobile radio environment, in the presence of Ricean fading, twofold antenna diversity and multiple reception capability, is considered. The capture probabilities and the average throughput are computed, and the issue of stability is addressed. It is shown that diversity can improve the system performance, although only to a certain extent. Some ext...
متن کاملStability 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a general packet reception model to incorporate multiple packet receptions since the collision channel model is no longer valid in such a scenario.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...
متن کاملOn the Stability of Five Types of Slotted ALOHA Systems with Capture and Multiple Packet Reception
The stability of slotted ALOHA systems with various types of capture phenomena and multiple packet reception capability is discussed in conjunction with the cusp catastrophe. The slotted ALOHA systems considered are classified into; 1) single packet reception with geometric capture, 2) independent multiple packet reception with geometric capture, 3) single packet reception with M -out-of-N capt...
