Content Replication in Mobile Networks
IEEE Journal on Selected Areas in Communications, Special Issue Cooperative Networking Challenges and Applications, Volume 30, N°9, October 2012
Performance and reliability of content access in mobile networks is conditioned by the number and location of content replicas deployed at the network nodes. In this work, we design a practical, distributed solution to content replication that is suitable for dynamic environments and achieves load balancing. Simulation results show that our mechanism, which uses local measurements only, approximates well an optimal solution while being robust against network and demand dynamics. Also, our scheme outperforms alternative approaches in terms of both content access delay and access congestion.
