  Abstract

The Slotted-ALOHA (S-ALOHA) and its variants have been widely used as the channel access protocol for the wireless sensor networks. The performance of the S-ALOHA systems depends largely on the collision resolution scheme. The S-ALOHA with the conventional binary exponential backoff scheme well operates in underload condition, while the ALOHA-Q being applied the reinforcement learning provides a good performance in heavy load condition. In this letter, we propose a hybrid scheme that dynamically selects the operation mode between above two schemes according to the load level. The simulation results show that the proposed scheme provides best performance in overall load range.
