“…We should also highlight the extensive surveys on search techniques in P2P overlays reported in Risson and Moors (2006) and Ahmed and Boutaba (2011). Due to the ever increasing trend towards green IT there has been a number of research efforts aimed at reducing energy consumption of P2P overlay networks, for a detailed survey of which we refer to Malatras et al (2012a).…”

a b s t r a c t P2P overlay networks have attracted significant research interest due to their utility as virtualized abstractions of complex network infrastructures, optimized to satisfy specific criteria, e.g. minimum delay or shortest diameter. In the context of modern pervasive environments, which are characterized by complexity, heterogeneity, dynamicity, and mobility in terms of the underlying networks, the utilization of P2P overlays accordingly offers a series of advantages by countering the aforementioned adverse characteristics. The widespread deployment of pervasive environments and the plethora of proposed P2P systems, both call for a systematic way to study related research works. In this paper we review related research on P2P (peer-to-peer) overlay networks in pervasive environments. In this respect, we therefore analyze relevant requirements and discuss the application and deployment of P2P overlays and systems on top of the networking infrastructures that are supported by pervasive environments. Aspects such as scalability, resource discovery, algorithmic complexity, security, and support for dynamicity are examined for existing research works, in an effort to identify the most suitable P2P overlay for the requirements set by the nature of pervasive environments. We also taxonomize P2P overlays using the well-established classification scheme in regard to their structure or lack of it. Furthermore, we study the notions of multi-layer and bio-inspired P2P overlays that have great synergies with pervasive environments due to their inherent characteristics, especially in terms of flexibility and robustness. By describing and critically analyzing existing systems and discussing current research and open issues, we aim to instigate further research in this domain, while at the same time this work should serve as a point of reference for state-of-the-art P2P overlays in pervasive environments.

Recent studies have shown that the total energy consumed by the Internet has followed an increasing trend over the years. A considerable part of this energy is wasted due to an inefficient utilization of edge devices, i.e., Personal Computers (PCs) and other user equipment in homes and offices. PCs are often left on even when they are not used (e.g., overnight or during weekends), while other edge devices, such as printers, IP phones, and displays, are typically kept always on, especially in public buildings. A number of solutions have been proposed for eliminating, or reducing, energy wastes due to edge devices. In this chapter we propose a general taxonomy for their classification. Then, according to the introduced taxonomy, we survey the main proposals appeared in the literature. Finally, we highlight some open issues.

“…Common approaches toward this goal include the use of proxies, optimizing task allocation, message reduction, location-based mechanisms, overlay structure optimization, and the 'sleep-and-wake' strategy [3]. The latter is one of the most popular approaches, based on the principle that the overall energy consumption of a peer-to-peer system can be significantly reduced if peers periodically switch from normal mode (high-power) to sleep mode (low-power) and vice versa.…”

SUMMARYAs peer-to-peer networks gather and share large sets of computing resources, their aggregate energy consumption is an important problem to be addressed, given the economic and environmental impact of energy production and use. This is particularly true for file sharing peer-to-peer networks, considered the vast number of nodes participating to these systems. To address such problem, this paper proposes a peer-to-peer file sharing model organized in two logical layers. The lower layer is composed of a set of peers providing the files to be shared. The upper layer includes a set of super peers organized to form a distributed hash table, whose purpose is indexing files and peers, including their availability status. Following a sleepand-wake approach, energy saving is achieved by letting peers cyclically switch between normal and sleep modes, where the time passed in normal mode by a peer depends on the number of files it provides. An energy-saving algorithm and an associated file search and retrieval strategy are proposed within this model. Simulation results show that more than 50% of energy can be saved using the proposed model and that more than 80% of file downloads start with no additional delay compared with a network in which all peers are always powered on.
