Before revision:   Finally, we consider two applications of our cache network model : (i) directly mapping to content distribution and (ii) generalization to wireless sensor network by jointly considering content caching and content compression.
After revision:  Numerical evaluations show that our algorithm significant outperforms path replication with traditional caching algorithms over some network topologies. Finally, we consider two applications of our cache network model : (i) directly mapping to content distribution and (ii) generalization to wireless sensor network by jointly considering content caching and content compression.
