This new Internet dimension can be beneficial for the society by facilitating the development of new technologies and applications that will improve our standards of living. In this study, we propose a novel traffic engineering policy that can satisfy the extremely strict requirements of the new traffic class associated with Haptic communications. Our proposed policy is based on Multi-Plane Routing (MPR) that consolidates various aspects in all-IP access infrastructures and enables network-wide path diversity. To this end, MPR has been remodeled and extended to facilitate Haptic communications. Our simulation results demonstrate that our proposed policy outperforms intra-domain routing protocols namely Open Shortest Path First (OSPF) and performs near-optimally. It will also become apparent that shortest-path solutions such as OSPF can not be used in order to handle Haptic communications in typical Internet network topologies. Finally, we formulate a binary optimization problem for the selection of the optimal Routing Plane (RP) in terms of the network effects such as delay, jitter and packet loss.","PeriodicalId":120403,"journal":{"name":"2017 24th International Conference on Telecommunications (ICT)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130401863","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 counter measure, the European Telecommunications Standard Institute (ETSI), proposes a mandatory Decentralized Congestion Control (DCC) framework to control the channel load. DCC algorithms are proposed to tune parameters such as message-rate, data-rate, etc. to avoid congestion. An important requirement for DCC algorithms is fairness, which ensures that vehicles experiencing similar channel loads are entitled to similar transmission parameters, in particular, message-rate and data-rate. Message-rate DCC (LIMERIC) ensures a fair message-rate selection, while data-rate DCC (DR-DCC) might end up with different data-rates, creating unfairness among the vehicles: vehicles with lower data-rate have a larger communication range than those using higher data-rates. Therefore some vehicles are less visible than others, which is detrimental to the reliability of the safety applications. To avoid this, the paper defines a novel packet-count based decentralized data-rate congestion control algorithm (PDR-DCC), which enforces fairness and hence improves the application-reliability. Simulation studies are performed to demonstrate that PDR-DCC avoids congestion in a fair manner. We also show the effect of fairness on the application-reliability by comparing the performance of PDR-DCC with message-rate (LIMERIC) and data-rate (DR-DCC) congestion control algorithms for a stationary vehicle warning application in a synthetic highway scenario and for various vehicular densities. We conclude that PDR-DCC outperforms LIMERIC, and DR-DCC in terms of application-reliability.","PeriodicalId":120403,"journal":{"name":"2017 24th International Conference on Telecommunications (ICT)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125182669","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 data traffic demand by moving users (vehicular users) has been constantly increasing. It is a key challenge in 5G to satiate the requirements of such moving users and provide good Quality of Experience (QoE), despite high mobility and traffic demand. In day-to-day life, there are several practical instances where cellular network is subjected to high load situation due to vehicular users. Groups of mobile users travel together (e.g. public transport) forming a moving network and pose congestion to cells they enter. Further, density of vehicular users change dynamically in a cell and at certain sites (e.g. signal lights), traffic jams arise frequently. Such scenarios would pose high load situation to respective serving base station. As a consequence, the cell site would experience high dropping and blocking of users and subject them to poor QoE. This work emphasizes on building mobility context awareness to alleviate such situations in traffic dense cellular networks. The strategies to predict user-cell transition are discussed and an algorithm to predict severity of vehicular user traffic is designed. Based on these mobility context information, suitable radio resource management (RRM), namely mobility load balancing and small cell activation/deactivation are pro-actively triggered. The simulation results exhibit substantial reductions in dropping and blocking of users, demonstrating improved QoE of users, despite high mobility and data demand.","PeriodicalId":120403,"journal":{"name":"2017 24th International Conference on Telecommunications (ICT)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133258881","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 more data being generated every day, especially with other associated paradigms like Internet of Things (IoT), there will be a lot of data to be stored and managed in the cloud. Thus, it will be very important to know which cloud service is more suitable for what kind of data and data-management tasks. To that end, this paper proposes and implements a cloud storage and collaboration tool called OmniBox. The first goal of Omnibox is to provide an evaluation of different cloud providers. The tool monitors different parameters and provides statistics such as upload throughput, download throughput, jitter, single-key and multi-key user accounts, and concurrent download time. The second goal of Omnibox is to provide a unified data management service where users can manage files from different cloud providers within a single interface. Additionally, OmniBox provides a feature called smart upload, where cloud providers are evaluated and suitable service is selected for uploading a file based on Quality of Service (QoS), file-type, file-size, upload throughput, download throughput, available space, jitter, and latency. Our current implementation includes Dropbox and Box Application Programming Interfaces (APIs).","PeriodicalId":120403,"journal":{"name":"2017 24th International Conference on Telecommunications (ICT)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114773974","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}

For example, some recent models assign resources based on the history of the users and the utilization of the cloud resource pool. Although these models have generally shown an increase in server utilization, they lack a cost-benefit analysis to know the profit margin obtained by the respective resource allocation schemes. Therefore, a complete model to analyze the cost could be a valuable tool for IaaS cloud service providers (CSP) to compare various resource assignment mechanisms. In this paper, we introduce a Relinquishment-Aware Cloud Economics Model (RACE) to calculate the net profit in a cloud provider environment. Our model includes various parameters such as service price, income from resources used by cloud service customers (CSC), service utilization, number of servers, electricity cost, and service relinquishment cost. The noteworthy contribution of our model is that it includes the cost incurred when users are leaving the cloud provider before their scheduled end time. We consider this loss as relinquishment cost or opportunity cost loss. After implementing our model, we evaluate different resource allocation schemes in a finite resource pool environment. The preliminary results show that blindly assigning more resources does not necessarily generate more profit.","PeriodicalId":120403,"journal":{"name":"2017 24th International Conference on Telecommunications (ICT)","volume":"160 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114677956","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}
