Mobile edge computing (MEC), as a promising technology, provides proximate and prompt computing service for mobile users on various applications. With appropriate incentives, profit-driven users can offload multi-task requests across heterogeneous edge servers. However, such incentive trade lacks a trustworthy platform. Due to the decentralized nature of MEC, trading information from players is easily tampered with by edge servers, which poses a threat to cross-server resource allocation. In this paper, we jointly consider incentives and cross-server resource allocation in blockchain-driven MEC, where the blockchain prevents malicious edge servers from tampering with player information by maintaining a continuous tamper-proof ledger database. Particularly, we propose two double auction mechanisms, namely a double auction mechanism based on breakeven (DAMB) and a more efficient breakeven-free double auction mechanism (BFDA), in which users request multi-task service with claimed bids and edge servers cooperate with each other to serve users. A delegated proof of stake (DPoS) based blockchain technology is leveraged to realize decentralized, untampered, safe and fair resource allocation consensus mechanism. The simulation results show that the proposed DAMB and BFDA can significantly improve the system efficiency of MEC.

基于区块链的移动边缘计算的联合资源分配和激励设计

移动边缘计算（MEC）作为一种很有前途的技术，为移动用户在各种应用上提供即时的计算服务。通过适当的激励，利润驱动的用户可以跨异构边缘服务器卸载多任务请求。然而，这种激励交易缺乏一个值得信赖的平台。由于 MEC 的去中心化特性，来自玩家的交易信息很容易被边缘服务器篡改，这对跨服务器资源分配构成了威胁。在本文中，我们共同考虑了区块链驱动的 MEC 中的激励和跨服务器资源分配，其中区块链通过维护一个连续的防篡改分类帐数据库来防止恶意边缘服务器篡改玩家信息。特别是，我们提出了两种双重拍卖机制，即基于盈亏平衡（DAMB）的双重拍卖机制和更高效的无盈亏平衡双重拍卖机制（BFDA），其中用户请求多任务服务并要求出价，边缘服务器相互合作为用户服务。利用基于委托权益证明（DPoS）的区块链技术，实现去中心化、不可篡改、安全、公平的资源分配共识机制。仿真结果表明，所提出的 DAMB 和 BFDA 可以显着提高 MEC 的系统效率。安全公平的资源分配共识机制。仿真结果表明，所提出的 DAMB 和 BFDA 可以显着提高 MEC 的系统效率。安全公平的资源分配共识机制。仿真结果表明，所提出的 DAMB 和 BFDA 可以显着提高 MEC 的系统效率。
