The advancement of information and telecommunication technology has resulted in lots of computing power service providers (CSPs) sharing resources. This effectively improves the utilization of computing resources and provides opportunities for users to find best network services. However, with the increase of similar or identical services, traditional service provision mechanisms become more complicated and face more challenges. To provide on-demand services for users and trusted service sharing platform for CSPs, we propose a blockchain-based distributed network service provision (DNSP) mechanism. Based on blockchain technology, we design a distributed network service (BBDNS) architecture and introduce trusted QoS model for users and profit model for CSPs. Meanwhile, we develop a bi-objective optimization problem, called BP-MATCH, to balance benefits between users and CSPs. Then, we define DNSP mechanism based on smart contracts. Furthermore, to solve BP-MATCH, we design Kuhn-Munkres based service matching algorithm (KM-SMA) and ant colony optimization-based service matching algorithm (ACO-SMA). Finally, we conduct a simulation experiment based on the generated dataset. Simulation results show that the proposed algorithm can obtain the optimal service matching decision under certain conditions, and DNSP mechanism can guarantee the efficiency of service decisions while providing trusted distributed service.

算力资源可信共享：利益驱动的异构网络服务提供机制


信息和电信技术的进步导致许多计算能力服务提供商（CSP）共享资源。这有效地提高了计算资源的利用率，并为用户提供了寻找最佳网络服务的机会。然而，随着相似或相同服务的增多，传统的服务提供机制变得更加复杂，面临更多的挑战。为了为用户提供按需服务和为通信服务提供商提供可信的服务共享平台，我们提出了一种基于区块链的分布式网络服务提供（DNSP）机制。基于区块链技术，我们设计了分布式网络服务（BBDNS）架构，并引入了用户可信的QoS模型和CSP的盈利模型。同时，我们开发了一个双目标优化问题，称为 BP-MATCH，以平衡用户和 CSP 之间的利益。然后，我们定义了基于智能合约的DNSP机制。此外，为了解决BP-MATCH问题，我们设计了基于Kuhn-Munkres的服务匹配算法（KM-SMA）和基于蚁群优化的服务匹配算法（ACO-SMA）。最后，我们根据生成的数据集进行模拟实验。仿真结果表明，该算法能够在一定条件下获得最优的服务匹配决策，DNSP机制在提供可信分布式服务的同时，能够保证服务决策的效率。
