A novel ultra-wideband( UWB) antenna is proposed in this paper,which has a band-notched characteristic for the interference between the UWB applications and the ieee802.11 a wireless local area network(WLAN) and the Wi MAX /C-band with combination of notched structures. The proposed antenna fed by coplanar waveguide( CPW),with modified U-slots and general U-slot in echelon patch which can be used to reject the frequency 5.15 to 5.825 GHz, 3.3 to 3.6GHz,and 3.7 to 4.2GHz. The simulation results show that the antenna has obvious band-notched characteristics in the notched band which can effectively prevent the interference of these narrow-band communication systems, and also has well radiation characteristics in the whole band.

The continuous growth in using mobile devices (e.g. smart phones, tablets, etc.) has increased the complexity in provisioning cellular network resources. Applying the cloud computing model in LTe (Long Term evolution) systems could be a good solution to increase LTe's performance by building a shared distributed mobile network that can optimize the utilization of resources, minimize communication delays, and avoid bottlenecks. One of the most important concepts used in mobile networks is service continuity. Mobile users moving from one sub-network to another should be able to seamlessly continue to retrieve content and use services (e.g. video streaming, electronic games, VoIP, etc.) that they want. In this paper, the Information Centric Networking/Content Centric Networking (ICN/CCN) approach is proposed to be used as a solution for service continuity in virtualized LTe systems. By using NS3 simulation experiments it is shown that the introduced approach is able to satisfy the performance related service continuity requirements.

Cloud computing offers utility oriented services to users. It also reduces the maintenance cost of the infrastructure as well as initial investment cost for users or startup companies. Due to the effectiveness of these services, many companies or institutes are trying to adopt this technology for offloading scientific or industrial applications. Virtualization in cloud computing is used to build virtual infrastructure which is managed by a load balancer. efficient design of the load balancer can reduce over or under provisioning. Load balancer contains virtual machine allocation technique which performs an important role with respect to power consumption of the data center. In this paper, we propose a system architecture and the virtual machine allocation algorithm for the load balancer in a scientific federated cloud. We have tested the proposed approach in a scientific federated cloud. experimental results show that the proposed algorithm not only increases the utilization of resources but also reduces the energy consumption. © 2014 ieee.

With depleting fossil reserves, increasing cost and global focus on reducing emissions, efforts for increasing participation of renewable energy sources have gained momentum. The smart micro grid technology is therefore growing very fast with the aim of improving efficiency and reliability and facilitating integration of distributed energy resources (DeR). The economical operation of smart grid is a very big challenge for operators in the deregulated power sector. Decision making with multiple conflicting objectives is a complex task and traditional methods do not work well in practical uncertain environment. This paper presents a technique based on time-varying differential evolution (TVDe) for optimal scheduling of DeRs in a micro-grid. A fuzzy decision making is carried out to rank the different solutions in order of their merit, considering both, cost and emission reduction objectives. Pareto optimal solution set is generated to cover the full operating range of DeRs. The proposed approach is validated on a 4-Distributed energy Resources and 14-Bus radial micro network and the results are found to be promising.

Cloud computing or Infrastructure as a Service(IaaS) solutions such as Amazon's elastic computing Cloud(eC2) are very attractive for many commercial enterprises especially in today's limited or shrinking IT budgets environments. Cloud computing has been considered as a newest delivery model of enterprise's IT gradually. This paper is aimed at helping companies analyze several characteristics of multi-instance cloud services and provide a decision-making model of purchasing instances under different instance utilization. Using the concrete instances prices, a comparison is made of usage charges under different utilization of four instance purchasing-patterns of one-year period. Based on analysis presented herein, a decision-making table in purchasing one-year instances and the corresponding cost savings under different utilization is concluded.

In this work an optimized approach of power control during soft handoff in downlink direction of WCDMA systems is proposed which is based on unbalanced power control scheme in which in the downlink direction all base stations in the active set transmit with different power to the MS based on the level of attenuation to the MS. Compared to balanced and unbalanced power control schemes adopted by 3rd Generation Partnership Program (3GPP) in downlink direction proposed power control scheme during soft handoff reduces the additional interference caused by multiple site transmission and minimizes the overall transmitted power, thus increases the downlink capacity but compromises in the macro-diversity gain due to soft handoff. The proposed scheme is particularly suitable in the environments which face poor propagation attenuation.

Noncontiguous Channel Allocation for Multimedia Communication in Cognitive Radio Networks

In conventional wireless systems, unless a contiguous frequency band with width at least equal to the required bandwidth is obtained, multimedia communication cannot be effected with the desired quality of service. We propose here a novel channel allocation technique to overcome this limitation in a cognitive radio network, which is based on utilizing several noncontiguous channels, each of width smaller than the required bandwidth, but whose sum equals at least the required bandwidth. We present algorithms for channel sensing, channel reservation, and channel deallocation along with transmission and reception protocols with two different implementations based on FDM-FDMA and OFDM-FDMA techniques. Simulation results for both these implementations show that the proposed technique outperforms the existing first-fit and best-fit allocation techniques in terms of the average number of attempts needed for acquiring the necessary number of channels for all traffic situations ranging from light to extremely heavy traffic. Furthermore, the proposed technique can allocate the required numbers of channels in less than 1 s with FDM-FDMA even (4.5 s with OFDM-FDMA) for 96% traffic load, while the first-fit and best-fit techniques fail to allocate any channel in such situations.

The paradigm-shifting transition in today's 'smart grid' is the perfect convergence of IT and OT systems that build an intelligent electricity system to distribute electricity more effectively all the way from transmission to customer appliances. While this transformation promises immense operational benefits to the utilities, it brings along significant security concerns in terms of increasing the enterprise-class security risk. The challenge for the utilities therefore, is to implement new approaches and tools in building a secure smart grid network that is reliable and resilient. This paper therefore introduces an 'integrated security management framework' that offers critical infrastructure-grade security, to multiple utility technologies in establishing an enterprise wide integrated security management system. This comprehensive security architecture offers improved interconnect of diverse systems, and establishes both physical security and cyber-security, integrated to all functional aspects of the grid.
