Diversity techniques can be used in multiband cognitive radio networks to improve the achievable data rate of the receiver. Maximal Ratio Combining (MRC) technique is used in relay assisted network to provide better receiver performance. Power bidding and allocation algorithm together with diversity technique is used to improve the performance of a hybrid multiband cognitive ...
Clustering and visualizing high dimensional dynamic data is a challenging problem in the data mining. Most of the existing clustering algorithms are based on the static statistical relationship among data. In the clustering process there are no predefined classes and no examples that would show what kind of desirable relations should be valid among the ...
Hand gesture recognition embedded system can be used as an interfacing medium between the computer and human using different hand gestures in order to control the computer. In this proposed system, a real-time vision based hand gesture interaction prototype which depends upon finger gestures using color markers is designed. The objective is to develop an ...
Music player are provided with very few search options. In this paper, two different user interfaces touch screen and audio recognition module are used to access music player. This can be used by both blind people as well as normal persons. The paper is based on the MSP430 microcontroller which has low power consumption. Feedback ...
Data that resides in a fixed field within a record or file is called structured data and have a defined schema. Unstructured data refers to information that either does not have a pre-defined data model and does not fit well into relational tables. Clustering gains importance in the fields of libraries (book ordering), insurance (identifying ...
Cloud based live media streaming is becoming one of the prominent scope among researchers. The growing popularity of the cloud has moved the Multimedia technology from being traditional to be highly modernized. Mobile devices have replaced the traditional way of viewing videos through PC’s. According to the recent survey, there is an exponential hike in ...
BYOD is a growing trend in corporate environments, where employees bring their own devices to work. Factors that have led to the growing popularity of BYOD include the benefits of work flexibility, increased productivity, and efficiency of employees. Despite these benefits, there are concerns over information security and privacy. Since BYOD allows employees to access ...
Smart home is the term commonly used to define a residence that uses a home controller to integrate the residence’s various home automation systems. The most popular home controllers are those that are connected to a Windows based PC. In the authors’ research they presented a part of smart home technology which using Bluetooth in ...
Energy efficiency is an important property of mobile and pervasive computing devices. Dynamic Voltage Scaling (DVS) is an energy saving technique; achieve this property by reducing energy dissipation of the core by lowering the supply voltage and operating frequency. In this paper, a simulation environment for testing of different DVS algorithms under EDF and RM ...
