Distributed Transient Network
Definition
From the Wikipedia [1]:
"Distributed Transient Network (DTN) is defined as: the type of network which is inherently decentralized by nature and consists mainly of nodes which are not per se constantly a part of the network and are able to join or leave at any time at any place in the network.
It is a well known paradigm within computer science." (http://en.wikipedia.org/wiki/Distributed_Transient_Network)
Discussion
Relation of DTN with P2P
From the Wikipedia article:
"well known DTN implementations are p2p and ad hoc computer networks. These networks however are implemented at very different layers of the OSI model. p2p is mainly software operating in the Application layer of the OSI model and forms a DTN which can be spread over the entire world. ad hoc computer networks however operate in the Network layer and are mostly networks that are physically close to each other."
