Abstract: In the Internet of Thing(IoT), wireless data transmission is an important way for the information acquisition layer to abtain the information. This paper presents a Data Reliable Gathering Cross-layer protocol(DRGC) for wireless sensor nodes in the Internet of Thing(IoT) for the event detecting and reporting. This protocol includes a clock synchronization algorithm that balanced precision and energy consumption, and a cross-layer data gathering algorithm that fuses MAC and routing strategy. Simulation results show that DRGC effectively prolongs the network lifetime and reduces the communication delay in comparison with LEACH and PEGASIS.
