An adaptive Slotted ALOHA Algorithm
نویسندگان
چکیده
Slotted ALOHA channels are inherent instability and must be equipped with proper control. In this paper, we analyze the principle of ppersistent control algorithm (pPCA) at first, we propose a novel auto-control algorithm which combines the multiple factor into p-persistent autocontrol algorithm (MF-pPCA). The simulation demonstrates that the novel algorithm can accelerate the adjusting speed and can acquire stable throughput on the conditions that there is large fluctuation of system load. Streszczenie. W artykule analizuje sie nowy algorytm pPCA umożliwiający poprawę szczelinowego algorytmu ALOHA w zastosowaniu do przesyłu danych. (Adaptacyjny algorytm szczelinowy ALOHA).

A Fast Adaptive Control Algorithm for Slotted ALOHA
—The control algorithm which is in order to achieve the aim of keeping throughput stability is needed in the Slotted ALOHA(S-ALOHA) protocol. The core of the control algorithm is to derive the accurate number of nodes. The classic control algorithm suffers performance loss when the system nodes change. In this paper, we addressed a Fast Adaptive (FA) algorithm to promote the performance of ALO...

متن کاملStochastic analysis of Aloha in vehicular ad hoc networks
The aim of this paper is to study the Aloha medium access (MAC) scheme in one-dimensional, linear networks, which might be an appropriate assumption for Vehicular Ad-hoc NETworks (VANETs). We study performance metrics based on the signal-over-interference and noise ratio (SINR) assuming power-law mean path-loss and independent point-to-point fading. We derive closed formulas for the capture pro...

This paper presents a Collision Resolution Algorithm which significantly improves the performance in terms of throughput and delay of the uplink contention channel existing in Wireless ATM MAC protocols such as MASCARA [9], where slotted ALOHA is employed. FS-ALOHA groups the requests arrived at the mobile terminals during a frame length and serves these groups on a FIFO basis using slotted ALO...
