(P2P) overlay networks are distributed systems in nature, without any hierarchical organization or centralized control. They are typically divided in two main classes: structured and unstructured [39]. Structured P2P overlay network have tightly controlled topologies and content is placed at specified locations to efficiently solve queries. Some well-known examples are Content Addressable Network (CAN) [44], Chord [15] and Pastry [45]. Such overlays use a Distributed Hash Table (DHT) as substrate, where

Sorting takes a vital role in the computer applications. This is a very interesting problem in computer science. Nowadays, there are many sorting
it using the original value. It is also used in many encryption algorithms Hash functions: Hash functions are mostly used in hash tables, to quickly locate a data record (for example, a dictionary definition) given its search key (the headword). Specifically, the hash function is used to map the search key to the index of a slot in the table where the corresponding record is supposedly stored. A hash table, or (a hash map), is a data structure that associates keys with values. The primary operation
Name: Ahmed Iqbal Roll No: 12k-2031 Section: R1 Practical Applications Of: 1. Binary Search Tree(BST) Binary search tree is used in many applications where information is always entering and leaving, for example, map and set objects in many languages libraries. Storing a set of names, and you look up on that on the basis of the prefix of name basically used in internet routers. Storing a path in a graph and for being able to reverse any subsection of a path in O (log n) is time basically useful

challenges faced by Internet, Distributed denial of Service is the critical concern for Internet, particularly to internet commerce. Distributed Denial of Service attacks can cause infrastructure problems and can disrupt communications on international level. Access denial to information by attacking the network in illicit way has become common nowadays. In this paper, we will discuss about how to detect and defend network service from the Denial of Service (DioS) and Distributed Denial of Service attack
architecture mostly depends on placing a network server as well as a network client on each computer. This concept provides access services from other computers running the same software. Based on how the nodes are connected to each other, P2P can be distributed into to categories. Unstructured P2Ps do not have any centralized system. Unstructured P2P have 3 types of categories called pure peer-to-peer, hybrid peer-to-peer, and centralized peer-to-peer. Each have a different thing assigned to them. Structured

Introduction From the ancient days human being has invented many new methods for communication in order to transfer their messages to each other. Now we can see that there are many methods using which we can establish effective communication. One of those reliable methods of communication is Mobile Ad Hoc network (MANET). It is also referred as Mobile mesh network. It is an automatic-configured network of mobile devices which are connected by the wireless links. It is a new technique of wireless
Ch 4 Encryption 4.1 Introduction Cryptography is the common term given to the art and science of keeping the text messages secret. It is not the purpose to evaluate in detail any of the mathematical algorithms that are used in the cryptographic process, but instead to provide a general view of the process and its uses. To introduce briefly one of the fundamental building blocks of all network security, one must know the process of encryption and decryption. A process that transforms the given information
Abstract Collaborative tagging describes the process by which many users add metadata (tags) in the form of keywords to share content. The main purpose of tagging is to categorize the web resources based on their content. The collaborative tagging services has grown in popularity on the web leads to cross referencing, thereby recognizing the privacy threat. In this paper, we proposed privacy-enhancing technology called tag suppression, used to protect end-users privacy. Index Terms— Policy-based
