Each cloud server facility is connected to the conventional power grid network and in addition it is supported by an attached renewable energy source (RES). We address the problem of energy-efficient task allocation in the system in the presence of a time-varying grid energy price and the unpredictability and time variation of provisioned power by the RES. The objective is to reduce the total cost of power consumption for the operator. The key idea is to match the VM load with the RES provisioned power. Each request for a task to be executed in the cloud is associated with a VM request with certain resource requirements and a deadline by which it needs to be completed. The cloud provider has to create a VM with the resource requirements of the request and to execute the VM before the deadline. We propose an online algorithm with given look-ahead horizon, in which the grid power prices and patterns of output power of the RESs are known a priori and we compare it with a greedy online algorithm. Numerical results on real traces of cloud traffic and renewable source generation patterns are encouraging in terms of the performance of our techniques and motivate further research on the topic.","PeriodicalId":6368,"journal":{"name":"2013 IEEE International Conference on Communications (ICC)","volume":"80 1","pages":"4217-4221"},"PeriodicalIF":0.0,"publicationDate":"2013-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74164484","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 solution enables transparent communication across address realms without keep-alive signalling and application layer code in end systems as required by the current recommended approach to NAT traversal. Although most protocols traverse the customer edge correctly, we identify a few protocols that require special processing because of the IP addresses carried in the user data. This paper first presents the results of protocol compatibility testing with CES and selects two protocols, SIP and FTP, for further study. The paper then reports the implementation of Application Layer Gateways for these two protocols and provides guidelines for processing other protocols. The proposed approach significantly cuts the session establishment delays typical in SIP. The presented work is a part of a larger project that proposes the Customer Edge Switching to replace NATs and introduce co-operative firewalls for protecting customer networks.","PeriodicalId":6368,"journal":{"name":"2013 IEEE International Conference on Communications (ICC)","volume":"65 1","pages":"2933-2938"},"PeriodicalIF":0.0,"publicationDate":"2013-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80196892","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}

As a result, user equipments (UEs) will be handed over from one RAT to another. To improve the robustness of the inter-RAT handovers and reduce cost, self-organizing networks (SONs) are used to configure the inter-RAT handover thresholds in an automatic and autonomous way replacing the current manual optimization methods. The handover thresholds can be configured cell-specifically or cell-pair specifically where a dedicated handover threshold is configured with respect to each target cell of handover. However, both optimization paradigms can fail to resolve all mobility failure events in some cells where radio conditions are not stationary along the cell border. In this paper, we propose a new paradigm for configuring and optimizing the inter-RAT handover thresholds based on the locations of UEs in the cell. Simulation results show that the new paradigm outperforms cell-specific and cell-pair specific schemes by resolving additional numbers of mobility failure events.","PeriodicalId":6368,"journal":{"name":"2013 IEEE International Conference on Communications (ICC)","volume":"26 1","pages":"6168-6173"},"PeriodicalIF":0.0,"publicationDate":"2013-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76317287","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}
