An IOW aims at business process orchestration with the particularity that this processes are heterogeneous, autonomous and independent. In fact, Information System (IS) components nowadays should cooperate despite their divergence to ensure a value added services .In addition, their audit requires horizontal communication with all stakeholders as well. In this work we use COBIT as IT Governance framework. We based our approach on its process oriented aspect to evaluate a real business objective with COBIT processes by a \"supply and demand\" way. This article presents first an architecture of the IOW, after that, it identifies mediation problems in the IWO to match an IS business objective with COBIT processes and proposes a solution. Then it presents the simulator of IT Governance IWO and opens new perspectives.","PeriodicalId":138330,"journal":{"name":"2014 International Conference on Next Generation Networks and Services (NGNS)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116642072","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 this reason, accelerated tests method is the reasonable procedure to be applied. It is used to determine the reliability of a product in a short period of time by accelerating the use environment. Application of the method of accelerated tests can save cost that we used to pay for overcoming the dilemma of not being able to estimate failure rates by testing directly at use conditions. In the method of accelerated tests, acceleration factor is known or there exists a mathematical model which specifies the relationship between lifetime and reliability or failure. This model proves its value not only as a way of a validation model for classical reliability models existing in the literature, but more, as a quantifier of reliability gain resulting when replacing or modifying parts (cost-benefit analysis).","PeriodicalId":138330,"journal":{"name":"2014 International Conference on Next Generation Networks and Services (NGNS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128427649","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 work, an enhanced three-time-slot per cycle time division duplexing (TDD) transmission protocol is proposed to the LTE-Advanced frame architecture. In such a protocol, UEs and the eNB can choose between different transmission schemes: direct transmission, pure Cooperative relaying (CoR scheme) using an intermediate relay station, or via the combination of Network Coding and Cooperative Relaying (NC/CoR scheme). A graph-based framework is proposed to solve the NP-hard combinatorial optimization problem. Our problem is transformed into a maximum weighted clique problem and used to provide optimal achievable rate regions for the hybrid transmission scheme, resource block assignment and relay selection. The proposed hybrid transmission scheme determines the best transmission strategy among direct transmission, CoR and NC/CoR in each three-time-slot cycle based on the system channel information as well as the queue length information. The simulation results show that our optimization algorithm significantly outperforms conventional schemes for both SISO and MIMO systems.","PeriodicalId":138330,"journal":{"name":"2014 International Conference on Next Generation Networks and Services (NGNS)","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115187131","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}

Generally, RSs work much better for those users on which they have more information about. Satisfying the new users becomes a challenge, as ensuring for them recommendations of quality is vital for the growth of the RS. Coping with this issue can be made by ensuring a certain brief interview with the user-called bootstrapping process-through which we acquire a user's feedback on a set of items, to subsequently enrich the user profile and inferring efficient recommendations. In this paper, we will propose an approach for bootstrapping a RS based on multi-criteria ratings and a method of computing weights of criteria taken from Multi-criteria Decision Making (MCDM).","PeriodicalId":138330,"journal":{"name":"2014 International Conference on Next Generation Networks and Services (NGNS)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126440804","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 find multiple paths, MP-OLSR uses the multipath Dijkstra's algorithm. The algorithm obtains considerable flexibility and scalability by using the cost functions, route recovery and loop detection mechanisms in order to improve MANETs performances. However, MP-OLSR presents some drawbacks. First, data packets are distributed into different paths by using Round-Robin (RR) scheduling algorithm. RR is incapable to balance load among heterogeneous multiple paths. Second, the cost functions return fixed values without adaptability to network conditions. To overcome these drawbacks, we proposed, in this paper, to integrate Weighted Round-Robin (WRR) scheduling algorithm to MP-OLSR for supporting heterogeneous multiple paths with different hop count. And, we proposed also a Fuzzy Logic Controller (FLC) to adapt the cost functions as function of hop count metric. Implementation and simulation experiments with Network Simulator NS2 are presented in order to validate our proposed goals. The results show that our enhanced MP-OLSR outperforms original MP-OLSR in terms of packet delivery ratio, end to end delay, jitter and routing cost.","PeriodicalId":138330,"journal":{"name":"2014 International Conference on Next Generation Networks and Services (NGNS)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114854702","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}

During the waiting phase, each SU can receive other packets that are organized on its own queue. Upon the release of a channel, the SUs begin the transmission. To avoid interference problems and conflict between SUs, it is necessary to implement a scheduler able to manage queues and assign the free channels to the SUs. In this work we apply an algorithm called Mono_scheduler and we offer a procedure, to assign the free channel to the SUs, manage the queues and ensure an equity value between transfer rates, by using Jain's Fairness Index (JFI) as a metric.","PeriodicalId":138330,"journal":{"name":"2014 International Conference on Next Generation Networks and Services (NGNS)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125648514","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}
