The MAC layer protocol for wireless sensor networks has reached a goal of the low-power and low-latency. Existing protocols using periodic sleep mechanism achieve energy efficiency, but the low duty cycle will bring considerable transmission delay, and the delay will accumulate at each hop. This paper presents a wake protocol one by one (Weak up One by One MAC, WOO-MAC), the introduction of an arbitration has been an active device (Mediation Device, MD) as the basis of managers, the agreement for the use of sleep mechanisms exists data forward interrupt and control overhead or other issues, using the method of MD waking each node and reducing the energy, accumulating delay will be decreased based on saving energy.
