Many applications for machine-to-machine (M2M) communications are characterized by large numbers of deviceswith sporadic transmissions and subjected to low energy budgets. This work addresses the importance of energy consumption by proposing a new Medium Access Control (MAC) mechanism forimproving the energy efficiency of IEEE 802.11ah, a standardtargeting M2M communication. We propose to use the features of IEEE 802.11ah MAC to realize a hybrid contention-reservation mechanism for the transmission of uplink traffic. In the proposed mechanism, any device with a buffered packet will first notify the Access Point (AP) during a contention phase before being given a reserved timeslot for the data transmission. We developa mathematical model to analyse the energy consumption of the proposed mechanism and of IEEE 802.11ah. The resultsshow that for a monitoring scenario, the proposed contention reservation mechanism reduces the energy consumption for asuccessful uplink data transmission by up to 55%.
