| Popis: | Slotted Aloha (SA) is a conventional distributed contention-based scheme in which the link time is divided into slots of equal duration and the users contend to access by transmitting with a predefined slot-access probability. Due to various applications and developments in wireless communications and networks, SA random access scheme and its various variants have gained renewed interests recently. In this paper we propose a novel grouping SA scheme with different grouping arrangements and (or) variable transmit probabilities (VTP) to improve throughput performance and achieve fairness among all user nodes. It shows improvements of throughput available with the proposed scheme by simply grouping user nodes and mapping VTPs onto the grouped slot positions for various wireless communications. |
