The RRMS Protocol: Fair Medium Access in Ad Hoc Networks

MAC level protocols in ad hoc networks must overcome the decentralized nature of the network and provide adequate throughput and fairness. This paper presents a new MAC protocol named Randomly Ranked Mini Slots (RRMS), which provides throughput at near channel capacity and good fairness as defined by a common sense criterion the authors develop. The protocol achieves this by utilizing random (pseudo noise) sequences, a receiver busy tone, and by sharing a minimal amount of information between two hop neighboring nodes. The performance of their protocol is compared to the Dual Busy Tone Multiple Access (DBTMA) protocol in terms of throughput and fairness.
