Spatial Data Query Support in Peer-to-Peer Systems



Motivation


Spatial data sets are used for many applications, e.g., GIS, CAD, …
P2P systems provide a distributed platform that is very scalable.
Pros:
Scalability, no central point of failure
Cons:
Very dynamic (unreliable), topology maintenance required

Rumor Riding: Anonymizing Unstructured Peer-to-Peer Systems JAVA

ABSTRACT
Although anonymizing Peer-to-Peer (P2P) systems often incurs extra traffic costs, many systems try to mask the
identities of their users for privacy considerations. Existing anonymity approaches are mainly path-based: peers
have to pre-construct an anonymous path before transmission. The overhead of maintaining and updating such
paths is significantly high. We propose Rumor Riding (RR), a lightweight and non-path-based mutual anonymity
protocol for ....etc

ABSTRACT


PEER-TO-PEER (P2P) computing systems have been thought of as a powerful paradigm for data sharing, and peerbased data management has attracted increasing interest from the database and information retrieval communities recently. Due to its desirab ....etc

Peer-to-Peer



An alternative to the client/server model of distributed computing is the peer-to-peer model.
Client/server is inherently hierarchical, with resources centralized on a limited number of servers.
In peer-to-peer networks, both resources and control are widely distributed among nodes that are theoretically equals. (A node with more information, better information, or more power may be “more equal, ....etc

Nowadays, the widely used internet technology and the reduction of the price of the computer hardware, the average computer system is possible to deliver multimedia data.Combined the use of the Internet and the capabilities in computer; computers can exchange multimedia data in the real world. Therefore this project aims to provide a convenient environment for communication in home computer users to perform broadcast and unicast TCP text chat and unicast UDP video/ audio chat over RTP. This program is functional, stable,user-friendly and user-f ....etc

Peer-to-peer computing consists of an open-ended network of distributed computational peers, where each peer shares data and services with a set of other peers, called its acquaintances. The peer-to-peer paradigm was initially popularized by file-sharing systems such as Napster and Gnutella, but its basic ideas and principles have now found their way into more critical and complex data-sharing applications like those for electronic medical records and scientific data. In such environments, data sharing poses new challenges mainly due to the lac ....etc

EVOLUTION OF PEER TO PEER DOWNLOADING
PEER TO PEER NETWORK
What is a peer to peer network?
A peer to peer network is a network that relies on the computing power & bandwidth of the participants on the network.
P2p networks are typically used for connecting nodes via largely ad_hoc connections.
Such networks are useful for sharing content files containing audio,video ,data & anything in digital format.

Randomized Protocols for Duplicate Elimination in Peer-to-Peer Storage Systems




INTRODUCTION

PEER-TO-PEER systems have emerged as cost-effective alternatives
for scalable data sharing, backup, and archival
storage , . Peers contribute data and storage and, in
return, gain access to data at other peers. Effective storage
management is an important issue in the deployment of such
systems. Data replication and caching are key enabling
techniques ....etc
