摘要：
This paper first analyzes the delay and energy consumption mechanism of SMAC. Then it proposes an improved DC-SMAC protocol by replacing the fixed duty mechanism with adaptive duty cycle mechanism, which adopts a priority discriminant function to make the node with more packets have the priority to access channel. The simulation results show that the proposed adaptive duty cycle mechanism can effectively reduce the network delay, increase the network throughput, improve energy efficiency of the node, and effectively enhance the network performance in the coordination with contention window adjustment mechanism.
