Fourth Generation (4G) is the next generation of wireless networks that will replace third Generation (3G) networks sometimes in future. 4G is intended to provide high speed, high capacity, low cost per bit, IP based services for video, data and Voice (VoIP).4G is all about an integrated, global network that’s based on an open system approach. At the(More)
— Cloud computing is an internet based pay as use service which provides three layered services (Software as a Service, Platform as a Service and Infrastructure as a Service) to its consumers on demand. These on demand service facilities provide to its consumers in multitenant environment but as facility increases complexity and security problems also(More)
Recommended by Dimitrios Tzovaras Two-dimensional digital filters have gained wide acceptance in recent years. For recursive filters, nonsymmetric half-plane versions (also known as semicausal) are more general than quarter-plane versions (also known as causal) in approximating arbitrary magnitude characteristics. The major problem in designing(More)

Abstract We study an M/G/1 queue with two stages of heterogeneous service and single working vacation.Using supplementary variable approach we derive the probability(More)
Now a days the importance of cloud computing emerge with many sectors in order to reduce economical Cost and improve the revenue with improving cloud service usability like IaaS, SaaS and PaaS services. In this connection when group users outsource their data to the cloud among the dynamic group no assurance about user privacy ,data integrity due to lack of(More)
An increasing number of databases have become web accessible through HTML form-based search interfaces. The data units returned from the underlying database are usually encoded into the result pages dynamically for human browsing. Search engines can help users to filter their desired information based on key words. The searched result is normally presented(More)
Cloud computing has been envisioned as the next-generation architecture of IT. Drop box is one of the most popular cloud storage services in the world. Dropbox was arguably the first cloud storage service that promoted mass adoption thanks to a referral program and an intuitive interface. Dropbox cemented its place on our mobile devices with a range of(More)
Mobile Ad Hoc Network (MANET) is a collection of mobile nodes communicating with each other without any infrastructure in a multi hop fashion. In a MANET, nodes are moving arbitrarily, so the network may experience rapid and randomly topology changes. This paper presents performance comparison of three dissimilar routing protocols i. e. Fisheye State(More)
There are many problems in science and engineering whose solution is applied in the design of Multi-Dimensional (MD) digital filters. Digital filtering finds an important position in the field of digital signal and image processing.Recently there had been a great deal of interest in the design and stability analysis of Two-Dimensional (2-D) recursive(More)
