The evaluation basis is mostly about the energy footprint of CCRCNs, but other factors, such as content offloading and Internet Sharing, are also taken into account. From the analysis it emerges that the current approaches to operate a CCRCN are not very profitable in terms of energy. Some produce very marginal savings, whereas the behaviour of others is strongly dependent on the operational conditions, thus being scarcely predictable. We thus point out the strengths and weaknesses of each, thus paving the way for the future greening strategies of CCRCNs.","PeriodicalId":158112,"journal":{"name":"2013 24th Tyrrhenian International Workshop on Digital Communications - Green ICT (TIWDC)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131459732","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}

Aside from environmental concerns and increasing energy costs, multi-core processors will soon be constrained by power consumption, which will eventually slow down the development of new technologies. In order to re-think and re-design wired network equipment and infrastructures towards more energy efficient approaches, the ECONET project aims at extending next generation networks, architectures and protocols in the green direction. This paper presents a prototype of one of the 13 platforms developed inside the project, namely the Distributed Router Open Platform (DROP). Results will show how the aggregation of multiple devices with green capabilities can guarantee a satisfying performance level while allowing huge energy savings.","PeriodicalId":158112,"journal":{"name":"2013 24th Tyrrhenian International Workshop on Digital Communications - Green ICT (TIWDC)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126620051","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}

The starting point of this work is Table Lookup Bypass (TLB), a new mechanism to reduce the energy consumption of a linecard overcoming the simple switch-off of network elements: TLB consists in bypassing the lookup operation performed by a router linecard and forwarding the incoming packets on a fixed outgoing interface. The paper defines four different heuristics able to detect a set of TLB operations that can be performed maintaining QoS constraints. The performance evaluation realized on a real network scenario shows that TLB can really improve the energy efficiency of IP network, both during peak hours and off peak hours: in this last case up to 90% of linecards can pass in TLB state.","PeriodicalId":158112,"journal":{"name":"2013 24th Tyrrhenian International Workshop on Digital Communications - Green ICT (TIWDC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130585156","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}

The considered utility function is the physical layer energy efficiency, which is measured in bit/J, and denotes the number of bits successfully delivered to the receiver for each energy unit drained from the battery. Both the cases in which the power dissipated in the transmitter circuit is included and not included in the utility functions are considered, and, also, the case in which there is a direct path between transmitters and receivers is briefly addressed. Analytic results on the existence of Nash equilibrium points are given, and extensive numerical results provide insight on the performance of the reviewed resource allocation algorithms.","PeriodicalId":158112,"journal":{"name":"2013 24th Tyrrhenian International Workshop on Digital Communications - Green ICT (TIWDC)","volume":"2019 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130630105","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}

Past studies have revealed that about 60-70% people leave their computers powered up 24/7 in the offices and at homes just to maintain the network connectivity. Huge amount of energy savings are possible if these computers can sleep during idle periods but still maintaining their network presence. Thus, a Network Connectivity Proxy (NCP) can be designed which is a software entity running on a low power network hardware such as switch or router and maintains the network connectivity for high power devices during their sleep periods. This paper describes the design, implementation and evaluation of a cooperative NCP that maintains the basic network and application level presence for the sleeping hosts. It also addresses the generic architecture of our NCP and its client softwares.","PeriodicalId":158112,"journal":{"name":"2013 24th Tyrrhenian International Workshop on Digital Communications - Green ICT (TIWDC)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124589631","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, with the user demand recently increasing at exponential pace, concerns about the cellular networks energy consumption have been raised. In response, energy-efficient resource management schemes have been proposed, which take into account energy consumption, and control how much of the network infrastructure is actually needed at different times, and how much can be temporarily powered off to cut energy consumption. Since most of the energy consumed in cellular networks is used by base stations (BSs), algorithms for managing BSs seem to be the most urgent development to achieve energy-efficient operation. This paper provides a quick overview of the BS management techniques that were recently proposed for cellular networks. In addition, an outlook on real implementation aspects, including current commercial products, and trends in the development of energy-efficient hardware is also given.","PeriodicalId":158112,"journal":{"name":"2013 24th Tyrrhenian International Workshop on Digital Communications - Green ICT (TIWDC)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122477707","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}

The model exploits a bi-objective processing performance index aggregating the cost of energy consumption and the cost of service delivery. An approximate solution to the related stochastic optimal control problem is presented. Based on the obtained results a collection of CPU frequency control governors for the Linux kernel was designed and implemented. Performance of the designed controllers was next experimentally compared to the performance of the Linux cpufreq_ondemand governor. The obtained results suggest ways to improve efficiency of the Linux kernel CPU frequency control mechanisms.

The workload is placed on the active servers until the servers are saturated. The idea of workload consolidation can be brought also to chip level by the OS scheduler to pack as much workload to as few cores as possible in a many-core system. In this case all idle cores in the system are placed in a sleep state, and are woken up on-demand. Due to the relationship between static power dissipation and temperature, this paper investigates the thermal influence on the energy efficiency of chip level workload consolidation and its potential impact on the scheduling decisions. This work lay down the foundation for the development of a model for energy efficient OS scheduling for many-core processors taking into account external factors such as ambient and core level temperatures.","PeriodicalId":158112,"journal":{"name":"2013 24th Tyrrhenian International Workshop on Digital Communications - Green ICT (TIWDC)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126600389","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 this paper we study the impact of the power consumption in the design of mobile radio networks. We perform the analysis for GSM and LTE systems. The main aim is the analytical evaluation of the optimal cell radius accounting for both the network sustainability and radio coverage constraints. Overall power consumption is expressed as the sum of static and dynamic terms. The former is due to Base Stations switch on and signaling, the latter is function of the traffic in the cell. We also evaluate the beneficial effects of power control on energy consumption and we compare results with the non-power controlled case. Finally, we analyze the reduction in power consumption for LTE with respect to GSM, that covers currently more than 80% of the worlds population.","PeriodicalId":158112,"journal":{"name":"2013 24th Tyrrhenian International Workshop on Digital Communications - Green ICT (TIWDC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125457966","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}
