Abstract -
Big Data era is upon us, a huge amount of data is generated daily, analyzing and making use of this huge amount of information is a top priority for all kinds of businesses. However, one of the most important problems that hinders the unanimous adoption of Big Data is the lack of security and privacy protection of information in the Big Data tools. In this paper we contribute to reinforcing the security of Big Data platforms by proposing a blockchain-based access control framework. We define the concept of blockchain and breakdown the mechanism and principles of the access control framework.

Abstract -
The movement pattern of users is of significant when evaluating the performance of different kinds of algorithms in wireless networking environments. In this paper, we propose an enhanced random waypoint mobility model (ERWP) to achieve a good trade off between reality and complexity. ERWP model uses two stochastic processes for speed change and waiting control, which make the movement of nodes smoother and more realistic. Simulation shows that the proposed ERWP model can provide a spatial distribution and movement behavior of a user in mobile region.

Abstract -
Recent developments in the computer industry owe a lot to innovations in networking infrastructure. Numerous protocols currently exist to exploit the Internets potential applicability. However, this situation causes unnecessary complexity in the configuration around units that compose networking systems in case of implementation of extended design. Network virtualization provides a solution to such complexities and forms a fundamental part of future network design. In particular, an overlay network in a physical infrastructure provides the freedom to maintain a customized network policy between distinct domains distributed across the Internet. This paper proposes an overlay network foundation comprising two systems. The first is multiple virtual servers that provide authenticated TCP services between an authorized client and a service provider. The second is a cloud-based system that provides cooperative applications on UDP between the supervisor on the client side and the service providers. The overlay network is operated by the virtual network interface card (vNIC) identifier, which results in simple embedding with no change in packet size. The systems architecture is based on an original design that constitutes a vNIC, a physical network interface card (pNIC), and a software. The vNIC creates the virtual host, while the relay system manages the software. Thus, pNIC provides an interface between the physical layer and the software layer. Finally, we conduct empirical testing of the proposed systems viability using real-life Internet-based research. The results show that our proposed system performs effectively and has good operability.

Abstract -
The objective of this paper is to analyze the performance of WiMAX Communication Model by implementing Stamford University Interim(SUI)-1 and Stamford University Interim(SUI)-2 communication channel. We evaluated the performance of WiMAX Physical layer by implementing wavelet in place of IFFT, under different combination of digital modulation techniques (16-PSK, QAM and 16-QAM) over SUI 1 and SUI 2 Communication Channels. In our research work, we investigated the physical layer performance on the basis of bit error rate (BER) and signal to noise ratio (SNR). The simulation results of estimated Bit Error Rate (BER) displays that the implementation of wavelet transformation is highly effective against the implementation of FFT transformation. The simulation results also showed that WiMAX system that use SUI-2 Channel had Significantly less Bit Error Rate then the Model using SUI-1 Channel.
