A Cross-Layer Approach for Minimizing Interference and Latency of Medium Access in Wireless Sensor Networks [PDF]
, 2010 In low power wireless sensor networks, MAC protocols usually employ periodic sleep/wake schedule to reduce idle listening time. Even though this mechanism is simple and efficient, it results in high end-to-end latency and low throughput.

CR-MAC: Cooperative Relaying MAC Protocol for VANETs
2019 Scientific Meeting on Electrical-Electronics & Biomedical Engineering and Computer Science (EBBT), 2019 In this paper, a novel cooperative relaying medium access control (CR-MAC) protocol is proposed for vehicular ad hoc networks (VANETs). Three data transmission modes have been offered to increase the throughput which are direct transmission (DT), cooperative relaying (CR) and multi-hop relaying (MHR).
