Distributed Channel Access with no Multiple Access Interference in Multi-Hop Wireless Networks

Abstract

The Scheduling with Interference Removal Established Network-Wide (SIREN) protocol is introduced that eliminates multiple access interference (MAI) in multi-hop networks. SIREN ensures that the receivers of a primary transmitter assigned a transmission turn have no MAI, and allows one or multiple concurrent secondary transmitters to transmit during the same transmission turn, as long as no MAI is created. Simulation experiments in ns-3 are used to illustrate the advantages of SIREN over IEEE 802.11b in terms of goodput, fairness, and delays.
