Abstract --In peer to peer systems the problem of free riders
and lack of motivation to share files result in dwindling life
time of p2p systems This also results in lack of interested files
in the system .Here in this paper we present a number of novel
ideas like building sub systems in p2p systems with separate
incentive for these sub system , peer to peer lending ,shared
sharing , p2p incentive Banks , to motivate people to share files
and form a co-operative society. As the life time of the system
directly depends on the number of files and the quality of files ,
This motivation helps in extending the life time of the system.
Keywords: P2P , Motivation , Lifetime , free
riding.
I. INTRODUCTION
The peer-to-peer (P2P) file sharing systems has a
lot of scope in the coming era . In this system we do not
have a dedicated server and clients as in the present system .
Instead every node can act as a client as well as a server .
This has given the system robustness and multiple sources
for clients. This has diminished the problems faced in
simple client server systems where a server failure can be
catastrophic for the entire network . In p2p systems a file
can be at multiple sources and each of these sources can
share parts of file resulting in better usage of a clients
downloading capabilities .So these type of file sharing
system are growing in popularity . As it grows in popularity
more and more problems affects these type of systems
exploiting their weak links.
A. Problem
P2p systems face their own problems which results in the
death of the system gradually in the long run when the
number of files shared decreases and as users start leaving
the system
The free riding problem affects the system in two
significant ways. First, the number of files in the system
becomes limited or grows very slowly. The number of
popular files may become even smaller as the time goes by.
This adversely affects user’s interest in the system and they
eventually pull out of the system. Users who share popular
files and also shares a large number of files pull out of the
system as they don’t really get the reward and recognition
for their sharing as much as they would have liked This
results in the system becoming poorer in terms of the
amount of files shared. and also good reputed files resulting
in still more people leaving the system This is a vicious
cycle and it may eventually lead to the collapse of the
system. Second, if only a few peers share popular files, all
the downloading requests are directed towards those peers.
This causes those peers to become hot spots, overloading
their machines and causing congestion on their network.
Peers frequently experiencing CPU overloads or network
congestion due to the P2P system may exit the system if it
affects their other routine activities .
In Whitewashing the users who have low
reputation leave the system and rejoin the system with new
identity
and lack of motivation to share files result in dwindling life
time of p2p systems This also results in lack of interested files
in the system .Here in this paper we present a number of novel
ideas like building sub systems in p2p systems with separate
