Power extension of grid to isolated regions is associated with technical and economical issues. It has encouraged exploration and exploitation of decentralized power generation using renewable energy sources (RES). RES based power generation involves uncertain availability of power source round the clock. This problem has been overcome to certain extent by installing appropriate integrated energy storage unit (ESU). This paper presents technical review of hybrid wind and photovoltaic (PV) generation in standalone mode. Associated components like converters, storage unit, controllers, and optimization techniques affect overall generation. Wind and PV energy are readily available, omnipresent, and expected to contribute major future energy market. It can serve to overcome global warming problem arising due to emissions in fossil fuel based thermal generation units. This paper includes the study of progressive development of standalone renewable generation units based on wind and PV microgrids.

“…There are many existing works focus on energy efficiency in wireless networks with traditional energy sources, while energy sustainability in sustainable wireless networks has not been well studied. Thus, we are motivated to revisit the research issues including energy modeling, resource allocation and network planning under the new dimension of energy sustainability in sustainable wireless networks [12,14,29] in this brief. We first present the characteristics of green energy supply.…”

The growing user demand and the expansion of wireless communications have led to a tremendous growth of energy consumption in wireless access. Due to the limited battery capacity of mobile devices and the increasing cost of energy from the electricity grid, energy efficiency has become one of the most essential research issues in wireless communications. Many studies have investigated how to minimize energy consumption to extend the network lifetime [1-3] or maximize energy efficiency or energy utilization [4-6] of a communication network powered by traditional energy.With the increasing concern on environmental protection and the preservation of natural resources, green energy sources, which refer to the energy harvested from nature resources and can be replenished without compromising the energy requirement of future generations like solar, wind, tides, etc., are anticipated to be widely used in next-generation wireless networks. The sustainable and eco-friendly characteristics can help to fulfill the ever-increasing user demand, while reducing the detrimental effects of conventional energy production. To promote sustainable wireless networking, communication industry has launched a few projects, e.g., Green Wireless Communication by King Abdullah University of Science and Technology [7], and WindFi: Renewable-Energy Wireless Base Stations by Steepest Ascent Ltd. [8]. In the field of wireless communication networks, green wireless devices, i.e., wireless devices like base station (BS), access point (AP) and relay node (RN) powered by green energy as shown in Fig. 1.1, have been developed to replace the traditional wireless devices. It was reported that wireless backbone devices, such as BSs, consume over 80 % of total energy in communication networks [9]. The deployment of green wireless devices in wireless backbone can significantly save the energy consumption and sustain the network operations. Therefore, it is anticipated that green wireless devices will be widely deployed to construct sustainable wireless network, i.e., wireless networks powered by green energy. Nowadays, many companies are upgrading existing conventional devices with wireless devices powered by green energy. For instance, Huawei [10] has extensively deployed green energy solution to power BSs in China, Africa, and the Middle East region; Sprint sets the goal that 10 % of its total electricity will be supported by renewable sources by 2017 [11].

“…Since the publication of that study, resource management for sustainable wireless networks has been studied in multiple contexts. In [1] and [3], the AP placement problem 0733-8716/14/$31.00 c 2014 IEEE has been re-visited in the context of sustainable WLAN mesh networks, in which a minimal number of APs with renewable energy sources are deployed in an area such that the quality of service (QoS) requirements of users can be fulfilled. In [4], by comparing sustainability performance of various routing algorithms, it is shown that traditional routing strategies without considering energy charging capability achieve poor performance; it is crucial to adapt routing decisions to the time varying energy supplies.…”

Abstract-There is a growing interest in the use of renewable energy sources to power wireless networks in order to mitigate the detrimental effects of conventional energy production or to enable deployment in off-grid locations. However, renewable energy sources, such as solar and wind, are by nature unstable in their availability and capacity. The dynamics of energy supply hence impose new challenges for network planning and resource management. In this paper, the sustainable performance of a wireless mesh network powered by renewable energy sources is studied. To address the intermittently available capacity of the energy supply, adaptive resource management and admission control schemes are proposed. Specifically, the goal is to maximize the energy sustainability of the network, or equivalently, to minimize the failure probability that the mesh access points (APs) deplete their energy and go out of service due to the unreliable energy supply. To this end, the energy buffer of a mesh AP is modeled as a G/G/1(/N ) queue with arbitrary patterns of energy charging and discharging. Diffusion approximation is applied to analyze the transient evolution of the queue length and the energy depletion duration. Based on the analysis, an adaptive resource management scheme is proposed to balance traffic loads across the mesh network according to the energy adequacy at different mesh APs. A distributed admission control strategy to guarantee high resource utilization and to improve energy sustainability is presented. By considering the first and second order statistics of the energy charging and discharging processes at each mesh AP, it is demonstrated that the proposed schemes outperform some existing state-of-the-art solutions.Index Terms-Energy sustainability, resource management, wireless mesh networks, renewable energy supply.
