“…The associated RBSs are equidistant to their common DC, and are for the sake of simplicity assumed to be separated by one network edge. Furthermore, forthcoming cell planing practices aim to increase area energy efficiency by favouring smaller cells in urban areas (Shahab et al, 2013;Fehske et al, 2009). Our model employs a small homogeneous mobile network composed of N RBS equidistantly distributed RBSs.…”

Abstract:In this paper, we propose a telco cloud meta-model that can be used to simulate different infrastructure configurations and explore their consequences on the system performance and costs. To achieve this, we analyse current telecommunication and data centre infrastructure paradigms, describe the architecture of the telco cloud and detail the benefits of merging both infrastructures in a unified system. Next, we detail the dynamics of the telco cloud and identify the components that are the most relevant from the perspective of modelling performance and cost. A number of well established simulation technologies exist for most of the telco cloud components, we thus proceed with surveying existing models in an attempt to construct a suitable composite meta-model. Finally, we present a showcase scenario to demonstrate the scope of our telco cloud simulator.

“…Therefore, how to design an appropriate green access network has become an important issue. Based on the suggestions in [3], we can achieve our goal for green communication via two strategies: First aspect is a cellular network can adopt the load adoptive hardware components (or software modules). It allows dynamically adjusting the traffic load to save energy.…”

Abstract-Targeting energy efficiency while meeting user Quality of Service (QoS) is one of the most challenging problems in future wireless networks. Since base stations (BSs) consume a high percentage of the total energy used in a wireless access network, saving power at the BS level is a major concern in green networks.In this paper, we propose an optimization model based on finding a tradeoff between reducing the number of active radio cells and increasing the transmit power of BSs to better serve all users in the system. The main contribution of the paper is the formulation of a multiobjective optimization problem that jointly minimizes the network power consumption and the sum of data unit transmission delays of all users in the network. Our proposed model is solved using an exhaustive search algorithm to obtain the optimal solution. Solving the optimization problem at hand is very challenging due to the exhaustive search high computational complexity. Therefore, we run simulations in a small network to give insights into the optimal solution. Specifically, we study different cases by tuning the weights of the power and delay costs. This is a distinctive and important feature of our model allowing it to reflect various decision preferences. Regarding these preferences and under various users spatial distribution, results show that our solution allows to select the optimal network configuration in terms of power consumption while guaranteeing minimal delay for all users in the network.
