Simulation of an Anti-Collision Algorithm for RFID Systems using a Code Division Multiple Access with Adaptive Interference Cancellation (CDMA/AIC) Approach with Dynamic Processing Gain (Gp)
… Access (TDMA) approach with anti-collision ALOHA-type algorithms. The time slots and frames of the tags are manipulated to deal with the collision problem. They work with different ALOHA protocol variants that are always trying to reduce the number of collisions compared to the previous …

Distributed Multiple Access for OFDMA Femtocells
… the case of using distributed, random access protocols as apposed to centralized interference mitigation techniques in the context of LTE femtocells. For this, we employ queuing analysis to compare the performance of centralized resource allocation schemes represented by an ideal power control …

Satellite multiple access protocols for land mobile terminals. A study of the multiple access environment for land mobile satellite terminals, including the design analysis and simulation of a suitable protocol and the evaluation of its performance in a U.K. system.
… is suggested for a large system. Reservation ALOHA schemes are appraised in a TDMA environment and an adaptive reservation multiple access protocol is proposed and analysed for a wide range of mobile communication traffic profiles. The system can cope with short and long data messages as well …

A dynamic and robust random multiple-access scheme for communication over satellite channels with interference
… proposes a combined system using the slotted ALOHA protocol as its random multiple access scheme along with direct sequence spread spectrum coding to provide channel robustness and low probability of detection. We estimate the transmission power achievable by a transportable interferer using …
