For the purpose of target localization, Multiple Input Multiple Output-Orthogonal Frequency Division Multiplexing (MIMO-OFDM) radar has been proposed. OFDM technique has been adopted in order to a simultaneous transmission and reception of a set of multiple narrowband orthogonal signals at orthogonal frequencies. Although multi-carrier systems such as OFDM support high data rate applications, they do ...

Data mobility is changing the way that businesses work. Organizations, lines of business, and even individual users can run applications, store data cheaply, and access content from anywhere. This puts IT in a tough position. What they need is a new approach for storing and accessing data: one where the business defines what it needs, ...

Data security is getting more complicated. Compliance is touching more and more data. Too much data is stored solely on user devices. You need data in the right place at the right time, with the visibility and control to ensure that it’s handled appropriately. This roadmap will help you choose the right content mobility solution ...

Data security is getting more complicated. Compliance is touching more and more data and too much data is stored solely on user devices. You need data in the right place at the right time, with the visibility and control to ensure that it’s handled appropriately. Your path to secure content mobility starts here. This roadmap ...

Cognitive Radio (CR) enables the efficient utilization of the limited radio spectrum, network resources and an unlicensed user can communicate in licensed spectrum without interfering a licensed user. In CR expected to address several operational challenges such as spectrum access in dynamic manner, providing Quality Of Service (QOS) between end-to-end and spectral heterogeneity. Hence it ...

A suitable model is presented in this paper for tracking and displaying of data about mobile objects in Web based Geographic Information System (Web GIS) and Location Based Service (LBS) applications. The application of network analysis is modeled and demonstrated by using the web services. GIS, LBS, end user, internet, web server and geo-database are ...

Uncertain reasoning which is from artificial intelligence community, a unified trust management scheme that enhances the security in MANETs is proposed. In the proposed trust management scheme, the trust model has two components: trust from direct observation and trust from indirect observation. In direct observation from an observer node, the trust value is derived using ...

In the domain of 21st century, mobile technology has revolutionized the user phenomenon of anytime, anywhere mobility opportunity and enables the users to enjoy with numerous flavors of apps. Now-a-days, most of the Smartphone’s users are using smart applications in the world. The backbone for this uprising is the operating system on which these applications ...

Due to the gathering of sickrooms and consultation rooms in almost all hospitals, the performance of wireless devices system is deteriorated by the increase of collision probability and waiting time. In order to improve the performance of wireless devices system, relay is added to control the access point and then the access of devices is ...

Power control in Multi-Carrier Code Division Multiple Access (MCCDMA) based wireless cellular network is of great importance. The power allocation methodology to enhance the performance of the MCCDMA system by limiting interference noise is at the expense of signaling overhead due to sharing of Channel State Information (CSI). The distributed algorithms that manage the power ...

Wireless Sensor Networks (WSNs) are increasingly used in data-intensive applications such as micro-climate monitoring, precision agriculture and audio/video surveillance. A key challenges faced by data-intensive WSNs is to transmit all the data generated with an application’s lifetime to the base station despite the fact that sensor nodes have limited power supply. The authors propose using ...

This whitepaper describes the limitations of legacy networks, especially for supporting BYOD. Understanding these limitations can pave the way for a successful BYOD management policy for campus and branch networks. Download now and find out how a re-architected network- flexible and scalable- makes BYOD easier to secure and manage, yet enhances speeds and allows employees ...

The rising demands on infrastructure, coupled with diminishing IT budget has caused major concerns for IT administrators such as infrastructure and maintenance complexity, mobile and remote access needs, security and disaster recovery, cost containment directives, and user productivity requirements. This technical report explores a storage solution with client virtualisation that can address these pressing concerns ...

Based on information gathered in TSIA’s annual Global Technology Survey, this report will look at the trend of remote support services being adopted over many different industry types. Through the continued improvement of remote control, desktop sharing and web collaboration, companies are able to use these capabilities to increase productivity by avoiding the loss of ...

While companies often focus on the individual interactions with their customers to ensure that they are satisfied with the service provided to them in that interaction, the companies can often fall short when looking at the complete journey of that customer on their way to purchase and beyond. The Harvard Business Review looks at how ...
