“…The authors find that using specific transmission mechanisms and configurations allows for an optimization of the considered metrics which favors all participating stakeholders. Methods for reducing energy consumptions in LTE Machine to Machine scenarios are considered in [7]. The authors consider trade-offs between responsiveness and energy consumption by means of prolonging the discontinuous reception cycles in the LTE standard.…”

Over the last few years, the importance of cloud services for file synchronization has been increasing. With the release of network enabled cameras like Google Glass the trend of synchronizing new photos with the cloud has emerged as an important new use case for mobile networks.Multiple stakeholder are interested in optimizing this synchronization process according to different orthogonal metrics. The end user is interested in a fast synchronization of images as well as a low energy consumption of the client used for upload to the network. The network operator requires a low number of network connections per synchronization of a batch of images in order to reduce the signalling load of the mobile network.This paper answers the question if the goals of the stakeholders can be achieved by selecting an appropriate synchronization scheduling mechanism. Therefore, we first present a model for the waiting time of cloud file synchronization services. Second, we perform measurements on the popular Dropbox service to obtain parameters required in the model. Finally, we perform a parameter study over the considered mechanisms and parameters, suggest a preferable algorithm and identify trade-offs favorable for all stakeholders.

“…Specifically, the maximum DRX cycle length, which is 2.56s, can be extended to a larger value in the order of several minutes to hours. This method has been extensively discussed in 3GPP meeting [6] and investigated in the paper [7,8]. In [7], the authors introduce a simple power consumption model to verify that longer DRX cycles would significantly lower the MTC UE power consumption.…”

The power efficient mechanism for MTC (Machine type communication) UEs in LTE-A networks is investigated in this paper. Extending paging cycle has been verified as one efficient method to reduce the power consumption for MTC UE. However, unnecessary SI( System Information) acquisition will be introduced if the extended paging cycle is larger than MP (Modification Period). Therefore, a two-MP based SI acquisition mechanism is proposed in this paper to fully eliminate the unnecessary SI acquisition. According to simulation results, the power consumption will be reduced greatly with the proposed mechanism.

“…However, the aforementioned mechanisms are still insufficient for MTC device, and DRX and idle state are adapted to improve device power saving in [62]. The potential of trading high delay for reducing MTC devices battery consumption is studied in [63]. (2) Extending paging cycle: 3GPP considers to extend paging cycle for M2M devices [1,2,64], but simulation results show that extending paging cycle beyond 2.56 s reduces the power consumption significantly for M2M traffic with small or medium values of inter-arrival time, but has no effect when the paging cycle is more than a limit [65].…”

A huge increase of machines attached to wireless networks is expected in the next few years. A large part of these machines will be covered by some wireless wide area networks. The arrival of cellular M2M (machine-to-machine) communication poses new requirements due to its specific characteristics. For most of the cellular M2M applications, the essential requirement is low energy consumption level or high energy efficiency. This survey provides a global view of the network technologies previewed for cellular M2M. In this survey, we study the existing classifications of M2M applications according to different criteria in the literature. The comparison of traffic characteristics between M2M and human-to-human is also proposed. Quality of service (QoS) requirements for typical M2M applications are resumed. The advance of reference M2M network architectures proposed by the Standard Development Organization (SDO) is investigated. We identify two possible effort directions to improve the energy efficiency for cellular M2M. The first one is to evolve the current existing 3rd Generation Partnership Project (3GPP) Consortium cellular networks to effectively support MTC (Machine Type Communication). The other direction is to design M2M-dedicated networks from scratch, which are often called low-power wide-area (LPWA) networks. We review, compare and categorize the proposals related to energy issues of cellular M2M mainly over the period 2011-2015 for the first direction. We introduce the development of LPWA networks for the other research directions. We highlight that the cooperative relaying, the design of energy-efficient signaling and operation, the new radio resource allocation schemes, and the energy-efficient random access procedure are the main points of improvement. It is important to jointly use the aforementioned approaches, for example, joint design of random access control and radio resource allocation, to seek for a trade-off between energy efficiency and other system performances.
