RRMAC: A sensor network MAC for real time and reliable packet transmission

Abstract

We designed RRMAC, a time division multiple access (TDMA) scheme guaranteeing hard real-time and reliable communication in a multi-hop convergecast network. We performed experiments to compare the performance of RRMAC and IEEE 802.15.4 and showed the advantages of RRMAC is WSN applications which require highly reliable real-time data transmission.
