Abstract:With an increasing demand for distributed systems storing big data, locally repairable codes (LRCs) have attracted attentions to recover lost data on failure nodes. An (r, t)-LRC has the property that each coordinate of codewords can be recovered from at most r other coordinates (repair set), and there are at least t disjoint repair sets for each coordinate, where r and t are called locality and availability, respectively. Wang, Zhang, and Lin recently have proposed a construction method of cyclic (r, t)-LRCs … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
