During the reserved time  One fundamental protocol that has significantly contributed to this efficiency is Slotted ALOHASLOTTED ALOHA and pure aloha are the category of aloha This protocol for sending packets on a network was conceived to enhance the performance of its predecessor, Pure ALOHA, by introducing a structured approach to data transmissionFlowchart of slotted ALOHA protocolwhere K Number of attempts. K max Maximum number of attempts initially is 15. T fr Average transmission time. TP   The core innovation of Slotted ALOHA lies in its method of time division; it divides the time interval into discrete slotsSlotted Aloha Protocol This segmentation is crucial for mitigating, though not entirely eliminating, the issue of data collisionsSlotted Aloha Protocol

The underlying principle of ALOHA in general, and Slotted ALOHA specifically, is to provide a medium access control (MAC) protocol that allows multiple devices to share a single communication channelLecture 10/11 Packet Multiple Access The Aloha protocol While Pure ALOHA allows devices to transmit data whenever they have a frame ready, leading to a higher probability of collisions, Slotted ALOHA improves on this by implementing a more synchronized frameworkFlowchart of slotted ALOHA protocolwhere K Number of attempts. K max Maximum number of attempts initially is 15. T fr Average transmission time. TP   In a Slotted ALOHA system, the continuous channel time is divided into specific, fixed-length time intervals known as time slotsUnderstanding ALOHA in Computer Network Data transmission is then strictly regulated to commence only at the beginning of these slots作者：FL Lo·1996·被引用次数：6—ALOHAis a simple and efficient way of allowing many machines with bursty data streams to communicate with a central computer. For cases where machines are  This eliminates the possibility of transmissions overlapping partially within a slot, which was a major inefficiency in Pure ALOHAUnderstanding Aloha Protocols in Shared Networks

The Slotted ALOHA protocol operates on the premise that each device only transmits its data at the start of an assigned or chosen time slotDifference Between Pure Aloha And Slotted Aloha If a device misses its designated slot or fails to transmit, it must wait for the next available slotALOHA, also called pureALOHA Whenever a user has a frame to send, it simply transmits the frame. If collision occurs, it waits for a random period of time and re-sends it again. – Sender can always find out if its frame was destroyed by listening to channel. For a LAN, feedback is immediate, while for a satellite  This intentional timing mechanism significantly reduces the probability of collisions compared to Pure ALOHALecture 10/11 Packet Multiple Access The Aloha protocol A flowchart of Slotted ALOHA protocol would typically illustrate this process: a device ready to transmit waits for the next slot boundary, sends its packet, and then waits for an acknowledgmentKnown as Slotted ALOHA, this protocoldivides the time interval into discrete slots, each equivalent to one frame's worth of time, to avoid collisions. However,  If a collision occurs (meaning two or more devices transmitted in the same slot), the devices detect this and retransmit their packets in a subsequent slot after a random back-off periodUnderstanding ALOHA in Computer Network

The effectiveness of Slotted ALOHA is evident in its ability to increase network throughput202525—Pure aloha is used when stations have data to send over a channel, whereasslotted aloha improves on pure alohaby reducing the chances of collisions between  While Pure ALOHA can achieve a maximum theoretical throughput of only 182020923—ALOHA is a medium access control (MAC) protocolfor transmission of data via ashared network channel. Using this protocol, several data streams originating from multiple nodes are transferred through a multi-point transmission channel. There are two types of ALOHA protocols – Pure ALOHA and Slotted 4%, Slotted ALOHA can reach up to 36Lecture 10/11 Packet Multiple Access The Aloha protocol8%Slotted ALOHA was invented to improve the efficiency of pure ALOHA. In slotted ALOHA we divide the time into slots of Tfr s(time to send each fixed size frame)  This improvement stems directly from the slotting mechanism, which ensures that if a collision does occur, the entire frames involved are lost, rather than just parts of them, as could happen in Pure ALOHAGated Slotted Aloha Protocol for Wireless Communication This makes Slotted ALOHA a more predictable and controllable MAC protocolUnderstanding ALOHA in Computer Network

Over the years, various enhancements and adaptations of the Slotted ALOHA protocol have been developed to further optimize its performance for different scenariosMS-ALOHA [83] Mobileslotted alohais a distributed slottedprotocolfor MAC that provides solutions for scalability and mobility. During the reserved time  For instance, Gated Slotted Aloha is a variation where a node, upon a successful transmission, can clear all packets that have arrived during its subsequent transmission attemptsSlotted Aloha Protocol Another development is MS-ALOHA (Mobile Slotted ALOHA), which is a distributed protocol designed to address scalability and mobility challenges in wireless networksFlowchart of slotted ALOHA protocol Where K Researchers have also explored its application in specialized environments, such as analyzing its performance on LoRaWAN networks to increase overall network throughput through a Slotted-ALOHA overlay作者：A Zanella·2025—It is a version of the legacyslotted ALOHA protocolin which each active user chooses a sub-channel (SC) to transmit its messages and, in each slot, it either  Furthermore, concepts like Persistent Multi-Channel Slotted ALOHA examine scenarios where users select sub-channels within the network, and performance analysis of a slotted CDMA ALOHA network explores the interplay of multiple access techniques作者：T Polonelli·2019·被引用次数：234—In this paper, we present an approach to increasenetworkthroughput through aSlotted-ALOHAoverlay on LoRaWANnetworks.
