Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) is the most popular channel access mechanism for Wireless Sensor Networks (WSNs). The random backoff and CCAs in CSMA/CA mechanism avoid the collisions. However, inefficient CCAs increase energy consumption. In order to reduce the energy consumption and enhance the reliability, a new channel access mechanism for IEEE 802.15.4e is proposed here. Besides, performance of the proposed MAC is analyzed in terms of reliability and throughput. Our models are compared with IEEE 802.15.4e MAC. It is found that the performance of the proposed MAC can outperform in terms of throughput, reliability, energy, transmission and channel access failure rate.
