Abstract :
Aiming at large-scale Wireless Sensor Network(WSN) whose main communication mode is broadcast, the main factors restricting access performance of contention-based Media Access Control(MAC) protocols were analyzed in this paper. Accordingly, a kind of adaptive probability Access mechanism was put forward, through which contention-based MAC protocols can transmit acknowledgement packet according to acknowledgement probability in the broadcast communication mode and adoptively adjust the acknowledgement probability on the basis of network status in the transmission window. Plentiful simulation results show that the MAC protocol based on the proposed adaptive probability acknowledgement mechanism has better access control performance and energy consumption performance.
