摘要：

Competitive MAC protocols become a good choice for Wireless Sensor Network because of their have good dynamic adaptability and so on. However, in general, there is a serious problem of data collision in competitive protocols, so a low collision MAC protocol based on broadcast messages is proposed in this paper, SA-MAC (Self-adaption Advertisement MAC). It uses broadcast messages to make the related nodes working in a scheduled time slot, while the unrelated nodes turning to sleep in the time slot, thus reducing the probability of data collision. Additionally, it designs the corresponding adaptive contention window mechanism and fast transmission mechanism according to the usage ratio of data buffer, so the network performance is further improved. The simulation results show that, compared with S-MAC and ADV-MAC, SA-MAC can reduce the energy consumption and delay while improving the packet delivery ratio. Moreover, it maintains a good network performance whether in the single-hop or multi-hop network environment.
