This growing trend highlights the need to improve network monitoring systems to cope with challenges related with performance, flexibility and security. SoftwareDefined Networking (SDN) and traffic sampling techniques can be combined to provide a toolset that can be used for enhancing network management activities and performance evaluation. In this context, this paper presents a proposal for supporting timebased sampling techniques in SDN, providing network statistics at the controller level and allowing the self-configuration of traffic sampling in network devices. The proposed solution, designed to improve the efficiency and flexibility of network measurement systems, takes into account the underlying need to establish a balance between the reliability of the collected data and the computational effort involved in the sampling process. The proof-of-concept results emphasize the potential of applying and configuring different time-based sampling techniques through a SDN framework and a small set of standard OpenFlow messages. Comparative results on the accuracy and overhead of each technique when sampling real traffic traces are also provided.","PeriodicalId":227652,"journal":{"name":"2018 26th International Conference on Software, Telecommunications and Computer Networks (SoftCOM)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115387570","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 main process of the cognitive radio is spectrum sensing. Energy detection (ED) method was found to be a promising candidate for spectrum sensing in the CR networks. However, the detection performance of the ED method is susceptible to noise fluctuations at the receiver side, known as noise uncertainty. To obtain better performance when noise uncertainty impacts ED process, it is necessary to incorporate a dynamic signal detection based on sensing threshold adaptation. In this paper, the influence of noise uncertainty and dynamic threshold adaptation for the ED of signals transmitted using orthogonal frequency division modulation (OFDM) is investigated. The major contribution of this work is the analyses of the influence of different parameters including: modulation constellations, noise uncertainty level, dynamic threshold and signal to noise ratio values on a probability of received signal misdetection. Simulation results show that a combination of some of the analysed parameters can significantly improve ED process for OFDM signals.","PeriodicalId":227652,"journal":{"name":"2018 26th International Conference on Software, Telecommunications and Computer Networks (SoftCOM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130374823","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}

This is due to the Slotted ALOHA used as an access protocol for the transmission of preambles and the use of random back-offs in case of Random Access Channel (RACH) failure. With the expected explosion of the number of devices in the coming years, the need for an efficient design to manage the access to the network becomes an urgent key issue especially with the reduced number of preambles available to perform the RACH procedure. To this end, the Third Generation Partnership Project (3GPP) proposed the Extended Access Barring (EAB) mechanism as a solution to control overload for MTC devices. In this paper, we propose an enhancement of the 3GPP EAB mechanism by expanding the contention space statically and dynamically with the aim to reduce collisions and to increase the success probability and therefore to fulfill constraints in terms of delay and energy consumption. An analytical approach along with simulations are provided in this paper to show the impact of this contention space expansion on the performance of the existing 3GPP EAB mechanism.","PeriodicalId":227652,"journal":{"name":"2018 26th International Conference on Software, Telecommunications and Computer Networks (SoftCOM)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130383664","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}

One of the main challenges facing the IoT is how to secure communication between these devices. Among all the issues, the Group Key Management is one of the most difficult. Although different approaches have been proposed to solve it, most of them use the same security parameters to secure all communications. Thus, if several services are provided by the network, communications within a service will be accessible to all network members even those which did not subscribe to it. Moreover, the compromise of a member will jeopardize all services. In this paper, we propose a highly scalable Multi-Group Key Management protocol for IoT which ensures the forward and backward secrecy, efficiently recovers from collusion attacks and guarantees the secure coexistence of several services in a single network. To achieve this, our protocol manages several groups with independent security parameters.","PeriodicalId":227652,"journal":{"name":"2018 26th International Conference on Software, Telecommunications and Computer Networks (SoftCOM)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128931067","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}
