Center node: "locally encodable and decodable codes for distributed storage systems"
  Abstract: We consider the locality of encoding and decoding operations in distributed storage systems (DSS), and propose a new class of codes, called locally encodable and decodable codes (LEDC), that provides a higher degree of operational locality compared to currently known codes. For a given locality structure, we derive an upper bound on the global distance and demonstrate the existence of an optimal LEDC for sufficiently large field size. In addition, we also construct two families of optimal LEDC for fields with size linear in code length.

Connected through hyperedge HE-1 (induced by source paper "erasure codes with symbol locality and group decodability for distributed storage"):
  with members:
    - "cooperative local repair in distributed storage"
    - "repair locality with multiple erasure tolerance"
    - "bounds on locally recoverable codes with multiple recovering sets"
    - "a family of optimal locally recoverable codes"
    - "on the existence of mds codes over small fields with constrained generator matrices"
    - "optimal locally repairable linear codes"
    - "balanced sparsest generator matrices for mds codes"
    - "on block security of regenerating codes at the mbr point for distributed storage systems"
