Abstract :
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.
