Contiki, a lightweight operating system for wireless sensor networks (WSNs), utilizes Radio Duty Cycling (RDC) to conserve sensor battery power. This project implemented and evaluated WPI- MAC, a reimplementation of the Crankshaft Media Access Control (MAC) protocol. Implemented as a new RDC driver within the Cooja simulator, WPI-MAC was compared via simulation against: ContikiMAC and X-MAC. Preliminary results indicate that under three common WSN traffic patterns ContikiMAC outperforms WPI-MAC in terms of energy efficiency and delay, but WPI-MAC yields lower average delays compared to X-MAC.
