Abstract

Because of the manner of wireless communication channel and limited communication resource, research of MAC protocol is one of challenging issues in Wireless Sensor Network (WSN). S-MAC is a representative MAC protocol for Wireless Sensor Network, but its energy strategy is still not perfect. Focus on energy efficiency, a new S-MAC based protocol that is called Packets Decision MAC (PD-MAC) is proposed. In PD-MAC, data-based RTS/ CTS is designed to bring forth details of data packets to all neighbor nodes. Based on these details, packets decision scenario is proposed to help neighbor nodes selectively abandon the right of packets transmission. So the amount of transmitted packets and probability of collision can be reduced reasonably, and energy consumption on them will be saved. With the simulations, the proposed protocol is evaluated in comparison with S-MAC from energy efficiency to accuracy of packets received by sink The performance of PD-MAC is verified to be efficient and competent.
