Trust Computation using Fuzzy Analyzer by Brijesh Kumar Chaurasia, Kapil Sharma, Varsha Dixit, Shekhar Verma Abstract: Vehicular Ad hoc Network (VANET) is a promising technology for providing the safety and efficiency in transportation. The distinctive features of VANET, including high mobility, variable density and open wireless medium, may lead to many security vulnerabilities. Due to the need for almost negligible reaction time, it is not feasible to verify a critical message or authenticate the sender before taking action. There is a need for a priori trust on nodes so that a vehicle can act in response to a message without verifying it. In this paper, trust computation scheme for variable density in VANET along with time efficiency for decision making is presented. In this work, fuzzy based analyzer is being used to evaluate trust level of messages in high, medium and low density environment whenever indirect trust value is available. The proposed scheme is also able to measure trust level of vehicle whenever indirect trust value is unavailable using Dempster-Shafer theory and PerronFrobenius theorem. Results and simulation show that viability of the proposed scheme.rn Keywords: Trust; Security; VANET; Fuzzy Logic; Malicious vehicle detection; Security in VANET.
Spectrum Management and Democratization in Morocco by Mohammed Ibahrine, Bouziane Zaid Abstract: This paper explores the history and current status of spectrum regulation in Morocco. The ANRT is described in details with a focus on its primary goals and activities followed by a discussion of the policies and the outcomes of the regulatory processes. The second part of the paper closely examines the administrative threats with regards to ANRTs independence and its policies of access competition and transparency. The paper also addresses the recent pressing issues of the states surveillance and privacy. This paper concludes with a delineation of two possible scenarios: a utopian or dystopian future of the spectrum and access to digital platforms in Morocco. Keywords: Telecommunications in Morocco; Spectrum; Management; Policies; Access; Transparency and Democracy,.
CoreLB: Towards Providing Multi-metric Score-based Load Balancing using OpenFlow and SNMP by Rodrigo Da Rosa Righi, Cristiano Costa, Clebio Dossa, Felipe Rabuske, Diego Kreutz Abstract: Load balancing is still one of the most crucial services offered by service providers. In spite of having several load balancing solutions in the market, this area has gained attraction with SDN and OpenFlow. In this paper, we present CoreLB, a new load balancing model that takes into account a broader range of metrics from both networking devices and servers to achieve a better balancing of the servers Keywords: Network Management; Software-Defined Networking; OpenFlow; SNMP Load Balancing.rn.

MEASURING USABILITY IN WEB: A PUBLIC UNIVERSITY CASE by Aykut Hamit Turan, Naciye Güliz Uğur Abstract: Web sites are developing as a critical segment of an enterprise's survival in our perpetually globalizing vying world. Small or large all organizations are developing Internet capabilities to provide services to their stakeholders to gain competitive advantage. As web sites are widely deployed in any industry by private or public organizations, it has become essential to investigate factors associated with organizational web site success. Web site usability has been taught to be an important indicator of web site evaluation and success. The purpose of this research is to assess and to investigate the usability perceptions of members of a public university, about the organizational website design and to tender some suggestions to enhance better and useful web sites. This study empirically tested original WAMMI framework in a Turkish university setting. We mainly found empirical support for the underlying theoretical model. Keywords: ICT; WAMMI; Website Usability; Public University; usability factors.
