A delay-aware MAC protocol with implicit RTS

The end-to-end packet delay is important for the application of wireless sensor networks. Reducing unnecessary and redundant handshake frame is considered as a promising way to minimize the end-to-end delay. Here, a protocol named compressed handshake media access control (CH-MAC) is p-resented by control frame compression with implicit RTS to improve delay performance. Simulation results show that the proposed protocol outperforms SMAC protocol.
