We study algorithms that allocate generation resources to demands by configuring switched paths from sources to loads. We consider the case when each demand can be met by two generators, one of them representing the central grid and thus shared among all demands.","PeriodicalId":338680,"journal":{"name":"2013 Sustainable Internet and ICT for Sustainability (SustainIT)","volume":"32 44","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120967744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, we have introduce an Energy-Efficient ARQ protocol, which is able to exploit the wireless channel correlation.

The introduction of proper software tools can indeed contribute to limit the environmental impact of inefficient car parking. By making use of a mobile application and a corresponding adequate information system, it is possible both to speed up the car parking process (from the user viewpoint), and to improve the parking areas' management. The application described here is characterized by some novel aspects: i) a QR code can be used to identify the parking spot, and to trigger the parking process; ii) a parking spot can be possibly reserved; iii) global information on parking occupancy can be made available to other applications to better manage services of public utility (e.g., urban traffic control). The benefits from the adoption of the proposed solution can be regarded as a small yet fundamental step toward a more sustainable approach to living in urban areas.","PeriodicalId":338680,"journal":{"name":"2013 Sustainable Internet and ICT for Sustainability (SustainIT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129972330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Even in networks that handle near-capacity loads very efficiently, energy savings increase substantially if the power consumption closely follows the offered load. Rate adaptation is a common denomination for a set of technologies that operate at different timescales to establish power-load proportionality. To propel their deployment, it is useful to assess how compatible they are with existing network systems and identify the design upgrades that can maximize their energy savings in future networks. The formulation of accurate energy profiles for current equipment is a first step in this direction. We run extensive power measurement experiments to compile the energy profiles of five network systems from multiple vendors. Our results show only negligible signs of power-load proportionality in all five cases: to really make a dent in the carbon footprint and operational cost of packet networks, future system designs must pervasively deploy rate adaptation technologies, especially those that control power state transitions at the packet timescale.","PeriodicalId":338680,"journal":{"name":"2013 Sustainable Internet and ICT for Sustainability (SustainIT)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127820796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

RPL has been designed to operate in energy-constrained networks with thousands of nodes, and therefore it is one of the most promising candidate routing protocols for Advanced Metering Infrastructure (AMI) networks. In this paper a performance evaluation of RPL is presented. An extensive study of the protocol is carried out with particular focus on Trickle, the algorithm adopted to control routing update distribution across the network. The performance of the protocol is analyzed considering different Trickle parameters in order to capture their impact on route formation and node power consumption. Results highlight that the nondeterministic nature of Trickle can lead to sub-optimal route formation especially when high message suppression is per-formed. In order to mitigate this issue, an enhanced version of the protocol, namely Trickle-F, is proposed in order to guarantee fair broadcast suppression. Trickle-F is demonstrated to be effective in obtaining more efficient routes with the same power consumption of the original version.","PeriodicalId":338680,"journal":{"name":"2013 Sustainable Internet and ICT for Sustainability (SustainIT)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134301503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One possible solution is the use of demand-side management (DSM) applying dynamic pricing mechanisms. However, instead of reducing peak loads, these mechanisms can lead to peak-shifting due to the herding effect of consumers' load-shifting behavior. To overcome this problem, we explore strategies of assigning (non-uniform) participation rates to consumers. We use a generic method to find a near-optimal distribution setting for participation rates. Our method allows DSM designers to tune the system toward consumer convenience. This means less frequent consumption schedule changes, in the price of system performance. In addition, consumers do not need to reveal their detailed consumption schedules (hence, their privacy is preserved). Using experiments, we show the impact of the herding effect and evaluate the effectiveness of the proposed solution. We thereby demonstrate price fairness for consumers. Finally, we apply our solution to a more realistic environment - one where consumers change their consumption behavior every day.","PeriodicalId":338680,"journal":{"name":"2013 Sustainable Internet and ICT for Sustainability (SustainIT)","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114698855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the rising cost of electricity and slow adoption of cleaner electricity-generating technology, servers should become more energy efficient. This paper looks at web servers, as HTTP is a common service provided by data centres. Reverse proxies are commonly used to improve the performance of web servers. In this paper, we consider how reverse proxies might be used to improve energy efficiency. We suggest that when demand on a server is low, it may be possible to switch off servers. In their absence, an embedded system with a small energy footprint could act as a reverse proxy serving commonly-requested content. When demand outstrips its capacity, the reverse proxy can power on the servers to meet this new load. Our initial results indicate that such a scheme could be practical and save significant power on servers with lower load.","PeriodicalId":338680,"journal":{"name":"2013 Sustainable Internet and ICT for Sustainability (SustainIT)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122231359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this end, smart meters have been deployed to collect realtime information about the current grid load and forward it to the utility in a timely manner. High resolution smart meter data can however reveal the nature of appliances and their mode of operation with high accuracy, and thus endanger user privacy. In this paper, we investigate the impact on user privacy when the consumption data collected by distributed smart metering devices are preprocessed prior to their usage. We therefore assess the impact on the successful classification of appliances when sensor readings are (1) quantized, (2) down-sampled at a lower sampling rate, and (3) averaged by means of an FIR filter. Our evaluation shows that a combination of these preprocessing steps can provide a balanced trade-off that is in the interests of both users (privacy protection) and utilities (near real-time information).","PeriodicalId":338680,"journal":{"name":"2013 Sustainable Internet and ICT for Sustainability (SustainIT)","volume":"135 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127348165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the major inconvenience of today's electricity tariffs between energy provider and its customers is their lack of flexibility, which renders demand response programs difficult to realise. In this paper, we propose a new supply demand agreement in order to foster power adaption (i.e. increase/decrease) collaboration between energy provider and data centres. To this end, we introduce contractual terms and based on those we propose reward and penalty schemes. Furthermore, we provide a signalling scheme which defines the communication requirements necessary to enable power adaption collaboration. Finally, we present a scheduling policy which helps the energy provider to request data centres in a fair manner for power adaption.","PeriodicalId":338680,"journal":{"name":"2013 Sustainable Internet and ICT for Sustainability (SustainIT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130400700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Similarly, the workloads of overloaded servers can be distributed onto other servers for a load balancing reason. Central to this approach is the migration of virtual machines at runtime, which may introduce its own overhead in terms of energy consumption and service execution latency. This paper experimentally investigates the magnitude of this overhead. We use the Kernel-based Virtual Machine (KVM) hypervisor and a custom-made benchmark for our experiments. We will demonstrate that the workload of a virtual machine does not have any bearing on the power consumption of the destination server during migration but it has on the source server. Moreover, the available network bandwidth and the size of the virtual machine do indeed. introduce a non-negligible energy overhead and migration latency on both the source and the destination server.","PeriodicalId":338680,"journal":{"name":"2013 Sustainable Internet and ICT for Sustainability (SustainIT)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130654997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
