SCALLOP:A SCALABLE AND LOAD-BALANCED PEER-TO-PEER LOOKUP PROTOCOL

MOTIVATIONS AND PURPOSE

Many large-scaled servers are implemented in a peer-to-peer distributed system due to:
Low cost of workstations
Availability of high speed network
Performance of the system is high due to:
Rapid response time
Less memory space

LOOKUP PROTOCOL

Response time=Lookup time +Service time
Shorter lookup forwarding path ....etc

Additional Director, Directorate of Technical Education, Chennai, India
Research Scholar, Government College of Technology, Coimbatore, India


ABSTRACT
Smart spaces are composed of smart and dummy nodes
which act as the source for providing service. A large
number of cluster groups are formed in the smart space.
Some of these smart spaces are mobile, some are Adhoc
and others are sensor ....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.

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

DYNAMIC SEARCH ALGORITHM IN UNSTRUCTURED PEER-TO-PEER NETWORKS--PARALLEL AND DISTRIBUTED SYSTEMS

Designing efficient search algorithms is a key challenge in unstructured peer-to-peer networks. Flooding and random walk (RW) are two typical search algorithms. Flooding searches aggressively and covers the most nodes. However, it generates a large amount of query messages and, thus, does not scale. On the contrary, RW searches conservatively. It only generates a fixed amount of query messages at each hop but would take longer search time. We pr ....etc
