Today over the Internet, communication and computing environments are considerably and significantly becoming more and more chaotic and complex than normal classical distributed systems that have some lacking of any hierarchical control and some centralized organization. There in the emerging of Peer-to-Peer (P2P) networks overlays has become of much interest because P2P networks provide a good quality substrate to create a largescale content distribution, data sharing, and multicast applications at the application-level. P2P networks are commonly used as “file-swapping” in any network to provide support in sharing of distributed contents. For data and file sharing, a number of P2P networks have been deployed and developed. Gnutella, Fast track and Napster are three popular and commonly used P2P networking systems. In this research a broad overview of P2P networks computing is presented. This research is focusing on content sharing technologies, networks and techniques. In this research, it is also tried to emphasize on the study and analysis of popular P2P network topologies used in networking systems. This research is also focuses, identifies and describes the most common architecture models of P2P networks and compares different properties, characteristics and features of four P2P systems—Fast track, Gnutella, Open FT and Napster. In P2P organization, every peer grosses mutually the parts of the server as well of the client. By way of a client, it can demand and copy its required record files from additional peers, and in place of a server, it can offer data files to additional peers. The survey basically analyzes and outlines the basic structuring of P2P networks together with their analysis, comparison, applications, advantages, and disadvantages. The survey presents numerous organized and unstructured P2P structures.

Wireless Sensor Networks is an infrastructure less, self-configured, reprogrammable, energy-aware network used in various applications. Many networks works on security of data including mainly ASCII values but not the non English end users. BDNA cryptography describes how to encrypt non English patterns but which leads to propagation of more bits transmitted means indirectly consumes more energy in WSN. In this we propose new steps to reduce the transmission of more bytes in the network. This gives high propagation speed in the network with minimum hash overhead.

Android is one of the most popular operating system for mobile devices and tablets. The growing number of Android users and open source nature of this platform has also attracted attackers to target Android devices. This paper presents the static and dynamic analysis of the Android applications in order to detect malware. In this work, we have performed permission based and behavioural based filtering of Android applications with the help of malware analysis tools. Our results revel that 80% of the applications request for dangerous permissions. 13% applications consist of malicious activities. Most of the applications are interested in the device data like contact lists, IMEI, IMSI, SMS etc. These results clearly indicate the need for better security measures for Android apps.

Over recent years there has been a considerable shift, from quality of service (QoS) to quality of experience (QoE), when evaluating video delivery across networks. Hence, we first explore the need for this shift towards user-QoE in the video delivery ecosystem. Further, we investigate major QoE metrics researchers use in the evaluation of DASH users. We point out a huge problem with DASH beginning with its transport layer protocol. DASH utilizes Transmission control protocol (TCP) as the transport layer protocol. Thus, we give an overview of the mechanism of Transmission Control Protocol (TCP) and two mechanisms greatly impacting the streaming process: (1) TCP congestion mechanism and (2) TCP Fast Start. This leads us to investigate the impact of these TCP mechanisms on DASH players and consequently user-QoE.
