These resources are available over a local or wide area network that appears to an end user or application as one large virtual computing system. The vision is to create virtual dynamic organizations through secure and coordinated resource-sharing among individuals and institutions. Access control to these resources is a problem difficult to manage, how to store and manage the security policies of such a system plays a key role. If these policies are not properly stored, the response time to access control requests will be dramatically increased. Grid Authorization Graph (GAG) was proposed to improve the authorization efficiency by eliminating the redundancy in checking security rules. This article proposes the Weighted Grid Authorization Graph (WGAG) as an enhancement to GAG which further improves the authorization efficiency by avoiding a lots of security rule checking. Finally, as proof of concept, we implement the WGAG simulator where simulations were done. The obtained results show that the proposed model can effectively reduce the complexity of security rule checking and gave better results than GAG.","PeriodicalId":192985,"journal":{"name":"2017 Sixth International Conference on Communications and Networking (ComNet)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116975069","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 progressive development of the real time applications, it is anticipated that the streaming traffic will contribute a significant amount of traffic in the near future. By combining priority queuing with Class Based Weighted Fair Queueing (CBWFQ), The Low Latency Queueing (LLQ) is a very important router discipline that aims to provide the needed quality of service (QoS) for each traffic category. Priority queueing is used to guarantee delay constraints for real-time traffic, whereas CBWFQ is used to ensure acceptable throughput for traffic classes that are less sensitive to delay. In this paper, we focus on developing a fluid model to capture the relation between elastic traffic and the real time traffic in a LLQ system under a quasi-stationary assumption. Our analysis of the CBWFQ system is based on some numerical observations and relies on the conservation of the average total number of elastic flows carried by the elastic system. Detailed packet level simulations of TCP flows show the accuracy of our analysis. The results presented in this paper allows a rapid performance evaluation of TCP traffic circulating in the actual IP networks.","PeriodicalId":192985,"journal":{"name":"2017 Sixth International Conference on Communications and Networking (ComNet)","volume":"505 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123067872","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, physical-layer security is emerging as a promising paradigm to protect the wireless communications against eavesdropping attacks. The fundamental principle behind physical layer security is to exploit the inherent randomness of noise and communication channels to limit the amount of information that can be extracted at the ‘bit’ level by an unauthorized receiver. In this paper, we investigate physical layer security issues in a two-way relay network. The idea is that when the eavesdropper channel is a degraded version of the main channel, the source and the destination can exchange perfectly secure messages at a non-zero rate. Moreover, we use green base stations as relays. Conventional energy sources are a huge source of atmospheric pollution. The renewable energy sources use natural resources and do not cause any pollution, hence they are termed green energy sources. We evaluate the security performance of cooperative relay transmission in Rayleigh fading environments in terms of secrecy capacity and intercept probability.","PeriodicalId":192985,"journal":{"name":"2017 Sixth International Conference on Communications and Networking (ComNet)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133921943","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}

It represents a key component of Internet of Thing (IoT) and is considered as one of the promising technologies which is being regarded in the future 5G Heterogeneous Networks (5G/HetNets). One of the most difficult challenges to support M2M communications is their huge number compared to available radio resources. Hence to deal with Random Access channel (RACH) overload and to better control the Access the 3GPP proposed the Access Class Barring (ACB) method. In this paper we proposed an algorithm to improve this method based on load balancing mechanism and a dynamic ACB factors, according M2M traffic category with respect to their access delay. Simulation results were done for testing the effectiveness of our proposed mechanism and show that using a base station selection method and tacking into account differentiated M2M services can increase the access success probability and reduce Access delay especially for devices with high priority traffic while satisfying the load balancing between Base stations (BS).","PeriodicalId":192985,"journal":{"name":"2017 Sixth International Conference on Communications and Networking (ComNet)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121266740","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}
