Clustered distributed storage models real data centers where intra-and cross-cluster repair bandwidths are different. In this paper, exact-repair minimum-storage-regenerating (MSR) codes achieving capacity of clustered distributed storage are designed. Focus is given on two cases: epsilon = 0 and epsilon = 1/(n-k), where epsilon is the ratio of the available cross-and intra-cluster repair bandwidths, n is the total number of distributed nodes and k is the number of contact nodes in data retrieval. The former represents the scenario where cross-cluster communication is not allowed, while the latter corresponds to the case of minimum cross-cluster bandwidth allowing minimum storage overhead. For the epsilon = 0 case, two types of locally repairable codes are proven to achieve the MSR point. As for epsilon = 1/(n - k), MDS codes achieve the MSR points for n = Lk, where L is the number of clusters.

We consider a cache network in which a single server is connected to multiple users via a shared error free link. The server has access to a database with N files of equal length F, and serves K users each with a cache memory of MF bits. A novel centralized coded caching scheme is proposed for scenarios with more users than files N <= K and cache capacities satisfying 1/K <= M <= N/K. The proposed scheme outperforms the best rate-memory region known in the literature if N <= K <= N (2)+1/2.

Multi-hop communication with multiple sinks provides better data propagation in terms of network throughput, bandwidth and energy consumption in energy and computationally constraint wireless sensor network. In this paper, we come up with the conceptualization of network coding scheme based transmission over a pre-defined minimum Wiener index spanning tree (MWST) based multi-hop routing access in a multiple sink scenario for energy constraint wireless sensor network. For effective data transmission between sensor nodes to sink node, we have proposed XOR based network coding Le. COPE. Contraiy to the previous methods in literature, we here deployed random sensor nodes over a pre-defined area. Each sensor node is connected with one and only one sink node depending on its Euclidian distance and number of hops between them and the same is implemented by nature inspired Particle Swarm Optimization (PSO) technique. Finally, the data transmission is enriched with the network coding approach for significant decrease in energy consumption and enhancement in network throughput gain.
