Current blockchain systems suffer from a number of inherent drawbacks in its scalability, latency, and processing throughput. By enabling parallel confirmations transactions, sharding has been proposed to mitigate these drawbacks, which usually requires frequent communication among miners through separate consensus protocol.In this paper, we propose, analyze, implement new distributed dynamic system substantially improve the throughput based on smart contracts, while requiring minimum...
Distributed applications that utilize <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">heterogeneous</i> blockchain systems have the potential to be widely deployed. In such applications, users from different blockchains can transact with one another through xmlns:xlink="http://www.w3.org/1999/xlink">cross-chain transactions</i> . There are two essential features of particular relevance for those during cross-chain transactions:...
BBR is a congestion-based congestion control algorithm recently proposed by Google. It proactively measures the bottleneck bandwidth and round trip times (RTTs) of connection pipe, based on which it governs its sending behaviors. Despite significant throughput gains latency reduction, some experimental studies reveal that may result in salient RTT-fairness problem, short-RTT flows can be starved allocation when comnetina with lons-R'I'T flows. In this paper, we study BBR's problem from...
Heterogeneous blockchains are expected to be increasingly deployed in real-world applications, making cross-chain transaction confirmations essential. Currently, for transactions usually accomplished through an intermediary, such as a relay chain, which may well become performance bottleneck. Sharding has been widely used improve the blockchain throughput parallel validations by distributing into multiple sub-communities, Yet, when sharding technique is directly applied over it results...
In order to achieve more dramatic spatial multiplexing gains, both industry and academia have pushed towards the massive Multi-User Multi-Input Multi-Output (MU-MIMO) systems. However, traditional linear precoding techniques do not scale up well with number of antennas, i.e., they either high implementation difficulties (zero-forcing) or sacrifice wireless capacity as a price (conjugate codebook-based precoding). this paper, we present novel scheme, BeamRaster, which is fast efficient scheme...
Cache and prefetching is now widely used in storage systems for disks to speed up accessing data. Although cache are well accepted technologies field, they unsuitable cloud because most of requests large files, which leads undesirable hit rate performance. To solve this issue, an improved head record (HRC) structure model proposed paper based on reshuffling disk technologies, aiming at improving reading performance a environment. Compared previous researches, has better read environment,...
With their instant transaction confirmation and high scalability, payment channel networks (PCNs), running off-chain in parallel with blockchain systems, have recently attracted a substantial amount of research attention. It has been shown that there exists significant gap between the theoretically optimal performance achievable given stringent privacy requirements practice. However, it remains unclear what fundamental limits key factors involved are, which turns out to be challenging...
