A multidisciplinary research area such as wireless sensor networks (WSN) have been invoked the monitoring of remote physical environment and are used for a wide range of applications ranging from defense personnel to many scientific research, statistical application, disaster area and War Zone. These networks are constraint with energy, memory and computing(More)
Mobile phones are the most commonly used devices in today’s scenario. The expanding use of mobile phones, telecommunication companies added feature such as MMS (Multimedia Messaging Service) in order to attract more customers. The Multimedia Messaging Service (MMS) has became very popular for sending messages containing multimedia objects such as images,(More)
In this paper behaviour or performance of three lens antenna; which having different thickness and weight are compared. These three lens antenna are the dielectric piano-hyperbolic lens antenna (DPHLA), phase correcting-Fresnel zone plate antenna (PC-FZPA) and phase shifting surface-lens antenna (PSS-LA). All these antennas are designed for Ka band with(More)
Traditional media, such as text, image, audio and video, have long been the main media resources and granted full support of standard desktop tools and applications. Interactive rich multimedia documents, adding resources such as video or synthetic animations and relying on complex synchronization among objects, are now making their entrance into the world(More)
Peer-to-Peer (P2P) refers to a class of systems and applications that employ distributed resources like storage, cycles, content, human presence available at the edges of the Internet, to perform a critical function in a decentralized manner. Peer-to-peer systems have been increasing in popularity in recent years as they are used by millions of users to(More)
The emerging technology, which allows high speed broadband wireless access, is the WiMAX technology which is based on the IEEE 802.16 family of standards. Mobile WiMAX (Worldwide Interoperability Microwave Access) is a wireless system based on the IEEE 802.16e [1] standard. In this paper occurrence of the handover in Wimax & LTE systems is shown and what(More)
It has been observed recently that the prominence of multidimensional data is increasing. Existing outlier detection techniques generally fail to work on multi-dimensional data. The need for analyzing high dimensional data has thus increased in today’s data trends. It has enormous application in medical domain, network intrusion and satellite imagery. Even(More)
Free-standing phase-correcting structures are very useful devices for various antenna applications. These devices are usually required to modify the incoming beam from a feeder antenna and transform it to obtain high gain or gain enhancement. The gain of any antenna is directly proportional to the aperture size of that antenna. For gain enhancement, we have(More)
