Binary Locally Repairable Codes ---Sequential Repair for Multiple Erasures
Wentu Song, Chau Yuen
Locally repairable codes (LRC) for distribute storage allow two approaches to locally repair multiple failed nodes: 1) parallel approach, by which each newcomer access a set of …
Locally Repairable Codes with Functional Repair and Multiple Erasure Tolerance
Wentu Song, Chau Yuen
We consider the problem of designing [n; k] linear codes for distributed storage systems (DSS) that satisfy the (r, t)-Local Repair Property, where any t'(<=t) simultaneously faile…
Local Codes with Addition Based Repair
Han Mao Kiah, Son Hoang Dau, Wentu Song +1
We consider the complexities of repair algorithms for locally repairable codes and propose a class of codes that repair single node failures using addition operations only, or code…
Weakly Secure MDS Codes for Simple Multiple Access Networks
Son Hoang Dau, Wentu Song, Chau Yuen
We consider a simple multiple access network (SMAN), where sources of unit rates transmit their data to a common sink via relays. Each relay is connected to the sink and to…
Locally Encodable and Decodable Codes for Distributed Storage Systems
Son Hoang Dau, Han Mao Kiah, Wentu Song +1
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 (L…
On the Solvability of 3s/nt Sum-Network---A Region Decomposition and Weak Decentralized Code Method
Wentu Song, Kai Cai, Chau Yuen +1
We study the network coding problem of sum-networks with 3 sources and n terminals (3s/nt sum-network), for an arbitrary positive integer n, and derive a sufficient and necessary c…
Erasure codes with symbol locality and group decodability for distributed storage
Wentu Song, Son Hoang Dau, Chau Yuen
We introduce a new family of erasure codes, called group decodable code (GDC), for distributed storage system. Given a set of design parameters {α; β; k; t}, where k is the number…
