Caching at a distance: a cache protection strategy in Eurasian jays [PDF]

Animal Cognition, 2016
A fundamental question about the complexity of corvid social cognition is whether behaviours exhibited when caching in front of potential pilferers represent specific attempts to prevent cache loss (cache protection hypothesis) or whether they are by-products of other behaviours (by-product hypothesis).

A Graph Neural Network Approach for Caching Performance Optimization in NDN Networks

IEEE Access, 2022
Named Data Networking (NDN) is a new architecture with in-network caching ability. NDN nodes can cache data packets in their cache store to satisfy further requests. Accurately caching popular content across the network is essential for NDN to reduce the

VANET Hybrid Collaborative Caching Strategy Based on PIT Similarity [PDF]

Jisuanji gongcheng, 2019
Aiming at the problem of repeated content transmission and long access delay in the Vehicular Ad Hoc Network(VANET),a hybrid collaborative caching strategy based on the similarity of Pending Interest Table(PIT) is designed.According to the PIT similarity

Popularity-Aware Closeness Based Caching in NDN Edge Networks

Sensors, 2022
By enabling name-based routing and ubiquitous in-network caching, Named Data Networking (NDN) is a promising network architecture for sixth generation (6G) edge network infrastructures. However, the performance of content retrieval largely depends on the

MARL-Based Distributed Cache Placement for Wireless Networks

IEEE Access, 2019
We investigate a distributed caching strategy based on multi-agent reinforcement learning (MARL) in a cache-aided network, where all wireless nodes have limited storage capacity and serve for certain coverage.

A Video Global Domain Cooperative Caching Algorithm for Named Data Networking [PDF]

Jisuanji gongcheng, 2018
In-network caching is one of the key aspects of Named Data Networking(NDN).The existing caching strategy of NDN takes insufficient consideration on caching cooperation among nodes,which can easily lead to the adjacent node to cache the same content and ...

Left-Right-Front Caching Strategy for Vehicular Networks in ICN-Based Internet of Things

IEEE Access, 2021
In Vehicular Ad-hoc Networks (VANET), vehicles act like mobile nodes for fetching, sharing, and disseminating important information related to vehicle safety, warning messages, emergency events, and passenger infotainment.

Decision-making for in-network caching of Peer-to-Peer content chunks: an analytical modelling study [PDF]

, 2014
In-network content caching has recently emerged in the context of Information-Centric Networking (ICN), which allows content objects to be cached at the content router side. In this paper, we specifically focus on in-network caching of Peer-to-Peer (P2P)

Caching strategies in opportunistic networks

2012 IEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks (WoWMoM), 2012
In this paper we examine content distribution in opportunistic networks. We design and evaluate strategies by which a node fetches and shares contents on behalf of other nodes, even when the contents are not of its own interest. We propose four relaying/caching options for improving the use of network resources: relay request on demand, hop-limit ...
