Item type:Publication, Access status: without files , Reducing content retrieval latency in ICNTo minimize content access latency within Information-centric Networking (ICN), its default caching strategy, 'Leave Copy Everywhere' (LCE), stores contents at each node along their delivery trajectory. However, this method inadvertently degrades caching efficiency due to the application of content replacement policies such as Least Recently Used (LRU). An indiscriminate replication of contents leads to lower cache hit ratios, decreased bandwidth utilization, and increased strain on content servers, resulting in longer content retrieval times. Thus, a nuanced modulation of contents' caching within the network is imperative to extend their proximity to their respective clientele. Identifying and strategically replicating high-demand contents across an optimum set of network nodes can maximize cache utilization and minimize cache pollution, notably improving network content accessibility and reducing retrieval times. We propose a caching strategy that dynamically, deterministically, and organically replicates the most popular contents to the optimum central cache nodes in the network, thus shortening the average path length that both requests and contents must traverse. Our caching strategy significantly outperforms LCE, achieving more than a 6% reduction in content retrieval path lengths. This paper comprehensively evaluates the proposed algorithm, elucidating its functionality and consequential repercussions on content redundancy, hit rate, and access time, which are paramount in the context of 6G systems. Leveraging the core principles of the introduced caching strategy, such as intelligent content distribution and proximity-based data access, can be vital for realizing Ultra-Reliable Low Latency Communications (URLLC) and enhanced Mobile Broadband (eMBB).Publicationtype: Conference Paper39 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , On popularity- and volume-based reduction of logistic costs in ICNInformation-centric networking (ICN) is structured as a distributed caching system in which user requests arrive at edge nodes and traverse the cache hierarchy to access their demanded contents. If an intermediate cache node holds a copy of the desired content, it is promptly delivered to the client within the local domain. Otherwise, it must be retrieved from external sources, causing longer access latencies and higher provisioning costs. To minimize the external logistic costs from the backhaul, we harness the potential of Interaction-based Caching to preserve the most popular and largest contents for a maximum time in the local network. This strategy increases the cache hit rate and reduces the total volume of data that needs to be imported from external sources and the associated logistic costs. Simulative performance evaluations prove the significant gains of the proposed algorithm in terms of hit ratio (over 10.64 %), external volume import (over 1.18 times relative to internal volume transport), and minimum content provisioning costs (over 5.1 times relative to internal transport costs) with respect to the Leave Copy Everywhere (LCE) strategy.Publicationtype: Conference Paper16 - Some of the metrics are blocked by yourconsent settings
