    The effect of smaller cells being placed in a heterogeneous network can improve the way energy is spent in a system. Handoff strategies, bandwidth allocation and path loss calculations in different scenarios show how this is possible as the size of the cell is decreased. As a result, users can experience the same or better capacities while maximising the capacity per unit energy spent. The per-ene... View full abstract»

    This paper focuses on energy efficient transmission in Amplify-and-Forward (AF) relay networks with bidirectional asymmetric traffic. A joint relay selection and power allocation scheme is designed to minimize the energy consumed per bit transmitted for both one-way and two-way relay networks. Through theoretical analysis, close-form solutions for energy efficient power allocation are derived at e... View full abstract»

  • Creating green incentives and mechanisms through packet-level energy accounting

    We explore the idea of accounting energy consumption of networks on packet-level. IP packets would collect the information of energy that they consumed at each hop and convey it further when travelling through the network. We describe a mechanism to do this accounting and analyze a few use cases including one where packets are given priorities based on how energy efficiently they have travelled th...

    We address the problem of coexistence between neighboring cognitive wireless networks operating in the TV White Space (TVWS). We derive an interference model to predict the range and level of interference generated in the TV bands by portable low-heigh antenna cognitive wireless access points (AP) in suburban and urban areas. Based on our model, we provide an analysis of the spectral availability ... View full abstract»

    This paper presents an analytical approach to quantify energy efficiency (EE), i.e., the bits per Joule performance of a large scale interference limited random wireless ad hoc network. Energy consumption is investigated at physical, medium access control (MAC) and routing layers. Communication between a user and its destination is facilitated by multihop relaying and Slotted ALOHA based MAC proto... View full abstract»

    In this paper, the energy efficiency of a femtocell base station is investigated and compared for various bit rates and for three different wireless technologies namely, mobile WiMAX, HSPA, and LTE. A power consumption model is proposed and applied in a network deployment tool to develop energy-efficient femtocell networks. Furthermore, it is investigated to what extent the introduction of sleep m... View full abstract»

    In recent developments, regulatory bodies are introducing flexible use of spectrum such as allowing the use of temporarily unoccupied VHF and UHF bands also known as television white spaces (TVWS). The networks exploiting such opportunity, hereafter called opportunistic networks, have equal right to access available TVWS. As a result, unhealthy competition to occupy the same spectrum would be inev... View full abstract»

    Spectrum sensing and compulsory idling are two important functionalities of the overlaid Cognitive Radio (CR) to facilitate the opportunistic spectrum access and incumbent protection for primary user systems. Since both the spectrum sensing and compulsory idling introduce energy-overheads to CR users, it is critical for CR to balance between these additional energy-overheads and its energy consump...

    This paper investigates the effect of small cell deployments in urban and dense urban areas from the energy consumption perspective. Considering a parametric power model for the legacy macrocell networks and the new emerging small cells, this study quantifies the power reduction gain by deploying heterogeneous networks consisting of a mixture of both technologies. As a part of the study, a framewo... View full abstract»

    Traditionally mobile operators have met the surge in mobile data traffic and the growing number of rural subscribers by deploying more macro base stations. This increases overall energy consumption, operational costs and carbon footprint of cellular networks. In this paper we investigate solutions for reducing the number and size of active macro cells following traffic load conditions in both homo... View full abstract»

    This article addresses some implementation challenges in the potentially very energy-efficient charge-sampling radios. Alternative ways to implement charge sampler in charge sampling radio are considered, and the impacts and spectral shape characteristics of the sampling jitter induced signal distortion are analytically studied in these cases. The analysis shows that the spectrum of the distortion... View full abstract»
