Abstract This paper introduces a new protocol routing medium access control (RMAC) that integrates the routing and medium access control (MAC) layer protocol. They can both reduce latency and save energy in the wireless sensor network (WSN) while most others propose protocols that sacrifice latency for energy. To make RMAC fit WSN better, we designed an easy and efficient routing protocol base station flooding (BSF) and then integrated it with a MAC protocol timing out MAC (TMAC) [1], while traditionally BSF and TMAC work separately at two layers. We call this two-layer protocol (TLP). We theoretically proved the advantages of RMAC over TLP and evaluated RMAC over NS-2. The simulation results show that RMAC spends half the latency of TLP, as well as consumes less energy than TLP.
