LoRaWAN generally operates as the standard of pure-ALOHA protocol and has the drawback of a high packet loss rate due to collisions [16]. Slotted Aloha. Aloha is an randomizing how protocol having two categories that are pure aloha and slotted oha. Consider the difference between pure ALOHA and slotted ALOHA under low load. The efficiency of an ALOHA system is that fraction of all transmitted frames which escape collisions that is which do not get caught in collisions. In slotted ALOHA, there is still a possibility of collision if two stations try to send at the beginning of the same time slot. In slotted Aloha, the shared channel is divided into a fixed time interval called slots. 开槽的Aloha使得站等到下一个时隙开始并允许每个数据帧在新时隙中传输。 在开槽的Aloha中可以通过在每次时隙开始时发出点的特殊站，在开槽的Aloha中实现同步。计算开槽Aloha的吞吐量的公式是S = G * E ^ -G，当G = 1是总传输数据帧的37％时，吞吐量最大。Not surprisingly, a complete analysis predicts that slotted Aloha's maximum efficiency (of about 36%) will be twice that of pure Aloha. Difference Between Network Topology and Network Protocols. Slotted ALOHA increases the capacity of pure ALOHA while reducing collisions. 184 when G=1/2. As a result, wireless packets may collide at a receiver if they are transmitted simultaneously. The only condition is that station must start its transmission from the beginning of the time slot. Pure Aloha has a very high chance of hitting a frame, hence the slotted Aloha is intended to outperform its efficiency. So that, if a station wants to send a frame to a shared channel, the frame can only be sent at the. The difference between the two styles is that Pure Aloha has more pronounced slits, while Slotted Aloha is less pronounced. Pure Aloha. The difference between slotted ALOHA and framed slotted ALOHA is that in framed slotted ALOHA, there is a synchronization among the users on the basis of a frame rather than a time slot.
