RPR works on a concept of dual counter rotating rings called ringlets. These ringlets are set up by creating RPR stations at nodes where traffic is supposed to drop, per flow (a flow is the ingress and egress of data traffic). RPR uses Media Access Control protocol (MAC) messages to direct the traffic, which can use either ringlet of the ring ...
Multiple Access with Collision Avoidance for Wireless (MACAW) [1] is a slotted medium access control (MAC) protocol widely used in ad hoc networks. [2] Furthermore, it is the foundation of many other MAC protocols used in wireless sensor networks (WSN). [2] The IEEE 802.11 RTS/CTS mechanism is adopted from this protocol.
Multiple access with collision avoidance (MACA) is a slotted media access control protocol used in wireless LAN data transmission to avoid collisions caused by the hidden station problem and to simplify exposed station problem.
As in any MAC protocol, the aims are to resolve contention and provide fairness. There are three main classes of media access protocol for ring networks: slotted, token and register insertion. The slotted ring treats the latency of the ring network as a large shift register that permanently rotates. It is formatted into so-called slots of fixed ...
Carrier-sense multiple access (CSMA) is a medium access control (MAC) protocol in which a node verifies the absence of other traffic before transmitting on a shared transmission medium, such as an electrical bus or a band of the electromagnetic spectrum.

There is a replay attack against the basic access control protocol that allows an individual passport to be traced. [3] [4] The attack is based on being able to distinguish a failed nonce check from a failed MAC check and works against passports with randomized unique identifiers and hard to guess keys.
