Communication driven era demands the use of new cryptographic protocols and hardware with reduced computational and structural complexity for resource constrained applications. This paper presents the hardware implementation of a key management scheme based on Elliptic Curve Cryptography (ECC) for applications in wireless sensor networks. Security-critical applications in WSNs rely on ECC for the key management since it offers increased security per bit of the key. This paper proposes efficient hardware architecture for the implementation of EC based key exchange in such a way that number of pre-stored values for key exchange and overall hardware complexity of the system are optimised without affecting security level. Algorithms for pseudo random sequence generation and message authentication code based on cryptographic one way function of elliptic curve point multiplication are developed. A single point multiplication unit based on Lopez-Dahab algorithm is time shared for pseudo random sequence generation and authentication to reduce the overall hardware complexity. Thus the proposed implementation scheme supports increased number of node addition phases. Evaluation of the design is done in terms of storage and hardware complexity. Proposed system gives 23.76% hardware efficiency over the existing EC based system. The design for GF(2163) has been simulated in ModelSim PE 10.4, synthesized in Xilinx ISE 14.7 and successfully implemented on Kintex-7 KC705 Evaluation Board.

Campus is one of the environment that needs a good network connectivity because it has a lot of user and require a rapid information exchange on a large scale. To equal the increasing number for those necessaries, the network becomes more complex and complicated, so it is difficult to manage the complex network. SDN is presented to facilitate the process of network control by separating control plane and data plane to optimize the performance of a network. In this paper, we will discuss about the migration of campus network (study case UPI) to SDN network. The main focus of this paper is about best controller placement by using POCO Algorithm that have MATLAB framework. We use node to controller maximum latency and controller imbalance parameter as consideration to find best controller placement.

Improvement of information technology especially in telecommunication system support wireless communication system must provide high data rate service. OFDM is the system that have high data rate and had been used as the method to overcome multiple channel effect But the weakness of OFDM system is PAPR. Large PAPR causes non linear distortion of signal and non orthogonal of sub carrier that caused performance of OFDM system will decrease. Recently, it has been developed a system as an alternative to OFDM system called OWDM (Orthogonal wavelet division multiplex). Basic idea of OWDM is replaced Inverse Discrete Fourier Transform (IDFT) with the Inverse Discrete Wavelet Transform (IDWT) for generating orthogonal sub-carrier. Like IDFT on OFDM systems, function of IDWT on OWDM system is modulator, while demodulator process used DFT (Discrete Fourier Transform) on OFDM and DWT (Discrete Wavelet Transform) on OWDM. This paper will compare the performance between OWDM and OFDM system on fading Rayleigh channel. Simulation both of system resulted same performance on multipath Rayleigh fading channel but different PAPR value PAPR of OWDM system is smaller than OFDM system. Thus OWDM techniques can be chosen as an alternative method to overcome the problems of the high PAPR value in OFDM techniques.

Gamified-Service is defined as a service desk which uses ITIL and gamification model to boost the motivation of service desk employees. Along the implementation of service desk, organizations find the challenge which is related to the human resource who deliver the service. Pressure at workplace and personal issues become trigger to decrease their productivity. According to this fact, standard service desk is not enough. We need persuasive approach to guarantee that employees are totally engaged. Moreover, we are challenged to ensure that good service desk is implemented, we need best practices of IT Service Management, it is Information Technology Infrastructure Library (ITIL). This research is focused on creating a framework to build, implement, and maintain good service desk with fully engaged employees.

In this research, the author create the application to calculate the Margin of satellites communication forsatellite coordination purpose. Margin is one of the indicator that determines whether the satellite communication system that we observe have destructive interference occurs or is free from interference. If there is interference in excess of the exposure limit, then the satellite operator must coordinate with the affected satellite operator [1]. Margin itself is calculated between the earth station transmitters, satellite and the earth station receiver. Differences cases that occur in satellite communication systems, such as differences in carrier, frequency, and communication areas, is affecting the calculations performed. In fact the number of satellites and earth stations very much, and the case is very varied so there arose the need to create applications that can facilitate the calculation of margin and can cover a lot of cases. World development of the internet makes the writer chooses to create Web-based applications using HTML, PHP and JS so that users can use the application without the need to install software first on their computers. Furthermore, the author also analysze a mitigation technique to anticipate such interference in a satellite communication system. However, these mitigation techniques only in terms of the calculations, does not involve cost that need to be spent or government regulations that limit the mitigation.

With the evolution in mobile systems technology it is possible to provide high data rate applications to the end user. Apart from the bottleneck problem in the core network, efficient utilization of the air interface remains a big challenge. Therefore, it is necessary to have intelligent resource management mechanisms in order to provide precise quality to the end users who have high expectation about the quality of service they receive. Here we propose a QoE based approach in order to improve the playback of a YouTube video in LTE network. The effectiveness and setbacks of our approach when put into practice on a running network will also be analyzed.

In the case of the artificial circular dielectric resonator which is encapsulated in a circular waveguide, the resonance characteristic is determined not only by a resonator thickness but also by a novel anisotropic permittivity value and a radius of a circular waveguide. In this paper, the relationship of its parameters is calculated and analyzed. The calculation is done by using the mathematical formulation which is derived from Maxwell's equations with proper boundary condition. The research is focused on the influence of the resonator thickness to the TM resonance characteristics of artificial circular dielectric resonator. The results show, the ability of novel anisotropic in p direction increase due to a radius of a circular waveguide enhancement for TM0, wave mode, whilst, the ability increase due to a radius of a circular waveguide reduction for TMU wave mode. A novel permittivity in p direction is effective reduce the resonant frequencies for thin resonator thickness.
