Macro reception diversity is a capability allowing a packet to be received by several base stations. In this letter, we propose a simple but accurate analytical model to estimate the macro diversity gain in pure and slotted ALOHA wireless networks. The proposed model takes into account Rayleigh fading, shadowing, and capture effect. We obtain simple closed-form formulas for the network packet loss...
Machine-to-machine (M2M) communication is expected to enable billions of devices to be connected by the cellular networks in the near future. The large number of devices involved in M2M will create a huge market potential but at the same time pose some challenges for 3GPP cellular networks. The challenges include massive access management, QoS provisioning, energy/power efficiency, etc. Nowadays,...

Recently, energy behaviour is being considered as an important key performance indicator when studying mobile networks. Reducing their operational cost is becoming more essential due to the huge increase of traffic accompanied by the increase in the electric bills. In this paper, we are going a step forward to study the possibility of a new type of energy behaviour of renewable energy-powered base...
Powering cellular base stations with renewable energy are one of the long-term strategies for achieving green networks and reducing their operational costs. As an energy provider, the power grid is evolving into a smarter one, which allows more energy-efficient cellular networks and enables cooperation and interaction with the smart grid. On one hand, cellular networks can use harvested renewable...
In recent years a lot of research work was dedicated to energy efficiency in cellular networks. An emerging field of interest in that direction is the use of renewable energy sources such as wind and solar — a type of energy that is bound to increase and develop. In this paper we survey the existing works and present the fundamental principles and motivations necessary for a thorough understanding...
In this paper, we analyze energy-efficient cellular networks that are based on renewable energy. We focus on hybrid energy base stations that are powered by renewable energy and power grid. This will provide the opportunity of obtaining green communication and integrating the renewable energy in the existing infrastructure at the same time. We propose a classification of the research problems and...
InterCell Interference Coordination (ICIC) is a major RRM (Radio Resource Management) feature recently included in wireless OFDMA networks. This paper studies OFDMA/ICIC algorithms. The model of networks considered is based on the LTE and WiMAX physical layers. After a state-of-the-art, we compare the simulation results of some of the proposed ICIC algorithms. We propose some adjustments to these...
