Cooperative Caching Scheme for Content Oriented Networking
Ran Liu, Hao Yin, Xuejun Cai, Guangxi Zhu, Li Hong Yu, Qilin Fan, Jie Xu · IEEE Communications Letters · 2013
In this letter, we propose a novel cooperative caching scheme for the next-generation Internet - content oriented networking (CON), trying to minimize the content access delay for mobile users. We formulate the caching problem as a mixed integer programming model and propose a heuristic solution based on Lagrangian relaxation. Simulation results show that this scheme can greatly reduce content access delay.
