Adaptive In-network Guidance Dissemination from Hot-Spot Nodes of Queries in Breadcrumbs-Based Information-Centric Networks

For several years, server access load and network traffic have greatly increased in content distribution networks because of growing content-sizes and higher request-frequencies. Breadcrumbs (BC) is an architecture that provides guidance information that directs a user to a node holding cached content. The target contents retrieved by this approach have the generalized meanings; videos, functions (programs), files, and any kinds of data, which are duplicated inside network, and also computing resources like CPU time and memory space. The BC is designed for reducing the loads of original servers and for forming autonomous information-centric networks. We have proposed extended methods for BC, called, “Active BC” and “User-Side Flooding,’ These methods provided higher nearby user-cache utilization. However, there still remains technical challenges to enhance BC hit ratio for queries, whereby they often could not provide sufficient guidance information. Thus, in this paper, we develop a BC method that adaptively creates new guidance information from hot-spot nodes to which more queries are routed.
