Information centric networks (ICNs) allow content objects to be cached within the network, so as provide efficient data delivery. Existing works on in-network caches mainly focus minimizing redundancy of improve cache hit ratio, which may not lead significant bandwidth saving. On other hand, it could result in too frequent caching operations, i.e., placement and replacement, causing more power consumption at nodes, shall avoided energy-limited delivery environments, e.g., wireless networks....
