Cooperative Communication (CC) and Machine to Machine (M2M) networks have recently emerged as promising techniques for improving spectral efficiency and extending network coverage. CC generated significant interest in the research community for optimizing Energy Efficiency (EE) in nextgeneration networks. However, envisioning CC as an energysaving solution for M2M networks gives rise to unresolved problems and significant challenges. In this paper, we discuss the enabling technologies for cooperation in M2M networks, the benefits and challenges of employing these technologies and the open research issues. We first provide an overview of each technology for cooperation in M2M networks. We then study the interaction between the cooperation techniques and the M2M energy-efficient networks employing each of these technologies. We also provide the latest standardization activities of M2M communication in LTE-Advanced networks.

“…In [7], mobile users are partitioned into groups and each group has a preassigned RS in the cellular architecture. Among the RSs for which at least one user in their group has BS-RS signal to-noise ratio (SNR) higher than a threshold value, only one RS is selected for the transmission in the next time slot.…”

Relay-based cooperative transmission in cellular network has been an area of tremendous research recently.Transmission via relays introduces power consumption at both the source and relay stations which may lead to less efficient system in terms of power consumption. Because of increasing energy cost for cellular systems and concern over environmental issues, an energy efficient design of resource allocation scheme in cooperative cellular network is of prime importance. In this paper, we propose a novel resource allocation scheme in order to maximize the energy aware system performance. The proposed low-complexity scheme allocates powers for base station and relay by using a strategy that minimizes required transmit power per unit achieved throughput and at the same time guarantees a predefined quality of service (QoS) which is specified in terms of minimum end-to-end data rate required by each user. Simulation results show that proposed scheme outperforms existing power allocation schemes by decreasing required power to guarantee the QoS without increasing system outage penalty, which is essential for green communication systems.

Abstract-Energy efficiency in cellular networks is a growing concern for cellular operators to not only maintain profitability, but also to reduce the overall environment effects. This emerging trend of achieving energy efficiency in cellular networks is motivating the standardization authorities and network operators to continuously explore future technologies in order to bring improvements in the entire network infrastructure. In this article, we present a brief survey of methods to improve the power efficiency of cellular networks, explore some research issues and challenges and suggest some techniques to enable an energy efficient or "green" cellular network. Since base stations consume a maximum portion of the total energy used in a cellular system, we will first provide a comprehensive survey on techniques to obtain energy savings in base stations. Next, we discuss how heterogenous network deployment based on micro, pico and femtocells can be used to achieve this goal. Since cognitive radio and cooperative relaying are undisputed future technologies in this regard, we propose a research vision to make these technologies more energy efficient. Lastly, we explore some broader perspectives in realizing a "green" cellular network technology.
