Abstract The main challenges in wireless communication is collision caused by simultaneous data transfer between two nodes on the same channel. In this context, medium access control (MAC) protocols have been improved primarily to try to avoid such collisions by helping nodes to decide when and how to access support. To meet the demand of machine-to-machine (M2M) communications, traditional protocols must be adapted to achieve remarkable energy efficiency; several requirements have to be respected when developing a MAC design for M2M system so as to meet the requirements of multiple and heterogeneous scenarios. In this article, we propose a multilayer MAC protocol with adaptive duty cycle that minimizes the energy consumed on idle listening via sending all messages in a variable active period according to load of traffic and returns to sleep mode. Simulation results illustrate that the proposal protocol outperforms other traditional MAC protocols in terms of energy consumption and average delay.

1 Introduction Machine-to-machine (M2M) [1] technology is a recent technology developed where several machines can share information between them without human intervention. These machines can be homogeneous or heterogeneous. M2M has a fast growth, and M. Ouaissa (B) · M.

the number of equipment increases in a big way. In most cases, these devices are powered by batteries and positioned in wide areas, so it is expensive to replace them or charge their batteries [2]. The medium access control (MAC) protocol for wireless sensor networks (WSNs) aims to define a policy of access to the radio medium so that sensors can transmit their data by attempting to reduce collisions with other data sent simultaneously nearby. The classification of MAC protocol types is divided into: contention-free and contention-based MAC protocols. The second type of protocol is more suitable for large networks, but collision and idle listening cannot be avoided when the network load increases [3]. Human intervention is not possible to change a battery; the lifetime of the network is related to the use of available energy. The energy consumption by a sensor node results mainly from the reception and sending of data packets. Therefore, in sensor networks, the scheme of an energy-efficient MAC protocol is a critical challenge for communication. Among the major sources of energy cons
