The duty-cycle protocols exists significant end-to-end delivery latency.In order to solve this problem, a new duty-cycle MAC protocol named PRMAC is proposed.PRMAC can delivery a packet multiple hops in a period based on cross-layer routing information advanced transmission, thus reduce network latency and improve energy efficiency.Simulation result in NS-2 shows that PRMAC can improve end-to-end delivery delay and throughput in traditional duty-cycle protocol without reducing energy efficiency.
