No collisions

Detailed explanation-1: -With ring topologies, the risk of packet collisions is very low due to the use of token-based protocols, which only allow one station to transmit data at a given time.
Detailed explanation-2: -In case of a device failure, the rest devices are not affected. Likewise, in the case of a security attack against an IoT device, only a single node is compromised, as endpoints operate independently of each other. Hence, star topologies offer better security than mesh networks.
Detailed explanation-3: -Ring Topology Data collisions are avoided as data packets are transmitted in one direction. Attaching more systems to a ring topology won’t affect the transfer speed bandwidth) as much as other layouts like a bus topology because the data is transferred at a consistent speed.
