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)
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 two-dimensional recursive filters is to(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)
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)
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)
Aspect Oriented Programming (AOP) provides new modularization of software systems through encapsulation of crosscutting functionalities, providing a clear isolation and utilization thereof. The trade-offs are typically a consequence of technical contradictions in requirements. We employ a data structure called a lazy counting based splay tree to analyze the(More)
