Cooperative mechanisms for information dissemination and retrieval in networks with autonomous nodes
Eva Jaho · 2011
In this dissertation we propose, model and evaluate novel algorithms and schemes that allow information dissemination and retrieval to be performed more efficiently in a modern networking environment. Most of these schemes are examined in relation to the content management tasks of content storage and classification. An inherent challenge lies in the need to manage the autonomy of nodes while preserving the distributed, as well as open nature of the system. To this end, we examine in some cases the development of incentives for nodes to cooperate while performing communication tasks. Finally, a novel attribute of most of the proposed schemes is the exploitation of social characteristics of nodes, focusing on how common interests of nodes can be used to improve communication efficiency.
