Réduction de la consommation énergétique dans les modules M2M utilisant la technologie LTE/LTE-A

Abstract : Machine-to-Machine (M2M) communication, which refers to the interaction between intelligent devices without human intervention, is gaining more prominence in mobile cellular networks. Long Term Evolution (LTE) and LTE-Advanced (LTE-A) networks are considered excellent candidates to support M2M communication. However, M2M communication over LTE/LTE-A networks faces some challenges. The main challenge is how to reduce energy consumption for M2M devices, as the majority of them are battery driven. The aim of this thesis is to propose solutions to reduce energy consumption in M2M devices over LTE/LTE-A technologies. We proposed two approaches; the first one consists of increasing time spent in low power mode by buffering data until reaching given thresholds of number of buffered data and maximum delay authorized. This approach allows to reduce signaling from idle state to connected state. Besides, it considers quality of service (QoS) requirements. The second approach consists of proposing two uplink schedulers which take into account the coexistence of M2M and Human-to-Human (H2H) devices. Both of them consider channel quality while allocating resource blocks, which have a consequence reducing energy consumption in M2M devices. Our second algorithm consider, also, delay constraint.
