ABSTRACT
With the popularity of mobile 3G and the mature of 4G network technology, the
mobile network applications have been of great concern. Because P2P network can take
full advantage of the edge of resources in the Internet, it has been a great success until
now. Considering that P2P technology and mobile network have much in common, how
to apply P2P Technology in the mobile network, how to play the technical
characteristics of mobile P2P network and how to make up deficiencies that the
resources of the mobile network are limited have become a very promising subject. This
article is dedicated to research the related factors of mobile P2P data dissemination
technology, which also is the core of the mobile P2P technology.
This paper describes how to apply P2P technology in the mobile and fixed network
and focuses on the mobile P2P data dissemination technology. P2P technology is an
important branch of distributed system. It follows the basic paradigm of the distributed
system. Of course, as different from other distributed systems, it also has its own
characteristics and limitations. Each node is a peer in the P2P network. Each node can
either be seen as the server can also be seen as a client.
Besides, there are many differences between mobile networks and fixed
networks. Mobile networks often are easy to be disturbed with high error
rate. Meanwhile, mobile devices are moving constantly. The feature takes the instability
to the mobile network. In addition, different mobile terminal equipments are in the
different design of the structure, and different mobile terminal equipments have
different power and manage quite limited resources. These bring new challenges to
mobile P2P technology.
Mobile P2P technology has different network model. So we should choose different
mechanisms to realize mobile P2P data dissemination, in order to ensure data
dissemination’s validity, reliability and safety. We also should take them into account
that how to connect with the fixed network, how to share the data resources of the
mobile and fixed network and how to make mobile terminals switch between fixed and
mobile networks in smooth way.
Mobile P2P data dissemination is a highly integrated technology. Because of its
specificity, we would involve many issues from hardware to software, from the fixed
