Abstract: We propose a new method for strengthening the security of information through a combination of signal processing, cryptography and steganography. Cryptography provides the security by concealing the contents and steganography provides security by concealing existence of information being communicated. Signal processing adds additional security by compressing and transforming the information. The proposed method, viz. Steganography Based Information Protection Method (SBIPM), consists of scanning, coding, encryption, reshaping, cover processing and embedding steps. Scanning, coding, encryption steps make the information unintelligible so that one cannot extract plain message. Embedding make the message invisible so that one cannot detect it. Reshaping spreads the message so that embedded message can be detected from distorted steganos by authorized receivers. Cover processing makes detection of embedded message more difficult since the distortion is either due to noise addition or due to message embedding. Simulation and steganlysis results show the method provides high security and the information is safe from various attacks.

Abstract: In this paper, we study this data staging problem by leverging the dynamic programming (DP) techniques to optimally migrate, replicate, and cache the shared data items in cloud systems with or without some practical resource constrains in an efficient way whiling minimizing the monetary cost for transmitting and caching the data items. Monetary cost is our primary interest as on one hand, the provision of the resources in cloud systems are usually based on pay-as-you-go fashion, and thus effective use of the platforms within budget constraint is always the user’s concern. In general, data staging algorithm in our applications is not only needed to figure out the user’s access patterns (i.e., a sequence of requests, each being made by certain node at a predicted time instant) but also required to migrate, replicate, or cache the involved data items across the network at particular time instants to optimize some performance metric for future accesses.

Keywords: Cloud computing, data staging and caching, resource constrains, data placement and migration.

Abstract: Ad hoc networks provide flexible and adaptive networks with no fixed infrastructure and dynamic topology. Mobile ad hoc networks (MANETs) consist of a collection of wireless mobile nodes which dynamically exchange data among themselves without the reliance on a fixed base station or a wired backbone network. MANET nodes are typically distinguished by their limited power, processing, and memory resources as well as high degree of mobility. In such networks, the wireless mobile nodes may dynamically enter the network as well as leave the network. Mobile ad-hoc network is a group of two or more devices or nodes with the capability of communication and networking. It is an infrastructure less network. Such network may operate by them or may be connected to a larger internet. Due to its mobility and self-routing capability nature, there are many weaknesses in its security. The security of the network from various attacks is an important issue in MANET application now days. Due to the dynamically changing topology, open environment and lack of centralized security infrastructure, a mobile ad hoc network (MANET) is vulnerable to many attacks. This paper focuses on mobile ad hoc network's routing vulnerability and analyzes the network performance under Distributed Denial of Service MANETS.

Keywords: Ad hoc Routing Protocols, AODV, DSDV, DSR, MANETs, Security attacks.

Abstract: In last decade an instruments called mobile phone being part of human. Today every one required application is based on mobile. Due to new innovation in technology, mobile phone becomes Smartphone that built on mobile operating system with more computing capability and connectivity. Smartphone allow user to install and use mobile application. Streaming is a method of transferring digital data with real-time characteristics in such a way that the recipient can view the content continuously while receiving the data. On the Internet, streaming has been a common technology for delivering audio and video content for years. Recently it has also become available for mobile phones. One of the most interesting, but also most demanding and challenging of these services is the streaming of multimedia content. Recently it has also become available for mobile phones. Today all the daily work become online, for that we required that applications such  as money transaction, e billing, e shopping like eBay, different mobile widget like social networking site face book, twitter etc. also available in Smartphone. Today Mobile Application become more and more advance with the advance technology of mobile computing so, My objective of research to find the HTTP Streaming Based on Mobile Node in the field of Mobile Application development so, that a smart mobile phone able to perform task using Mobile Augmentation that it was not performed due to hardware constraints, n/w constraints or s/w constraints.
