Two-Hop Cooperative Caching and UAVs Deployment Based on Potential Game

نویسندگان

چکیده

This paper explores the joint cache placement and 3D deployment of Unmanned Aerial Vehicle (UAV) groups, utilizing potential game theory a two-hop UAV cooperative caching mechanism, which could create tradeoff between latency coverage. The proposed scheme consists three parts: first, initial 2D location groups is determined through K-means, with optimal altitude based on coverage radius. Second, to balance transmission delay coverage, MOS (Mean Opinion Score) are designed evaluate performance UAV-assisted networks. Then, modeled, transfers optimization problem into maximization whole network utility. locally coupling effect resulting from action changes among UAVs considered in design utility function. Moreover, log-linear learning applied solve problem. Finally, simulation results verify superiority terms achievable compared two other tested schemes. ratio close 100% when number 25, user 150; addition, this outperforms benchmarks it comes maximizing users.

Social-Based Cooperative Caching in multi-hop wireless networks

Data access is an important issue in Delay Tolerant Networks (DTNs), and a common technique to improve the performance of data access is cooperative caching. However, due to the unpredictable node mobility in DTNs, traditional caching schemes cannot be directly applied. In this paper, we propose DAC, a novel caching protocol adaptive to the challenging environment of DTNs. Specifically, we expl...

Home Based Cooperative Web Caching

Web caches in a cooperative cache array must have a method to determine if another cache in the array has an object corresponding to a specific URL. This is achieved by a broadcast query in Internet Cache Protocol (ICP) based cache arrays. An alternative approach is taken in Cache Array Routing Protocol (CARP), where a particular URL can only be cached in a designated cache. Both approaches hav...

A novel cooperative game between client and subcontractors based on technical characteristics

Large projects often have several activities which are performed by some subcontractors with several skills. Costs and time reduction and quality improvement of the project are very important for client and subcontractors. Therefore, in real large projects, subcontractors join together and form coalitions for improving the project profit. A key question is how an extra profit of cooperation amo...
