modeling: An HTML repository from yyds-xtt

This is an optimal model of cooperative caching policies network-aware to join placement caching problem and mult-hops requests routing problem for the heterogeneous cellular networks. The objective is to decrease delay and increase cache hit. There are constraints of storage and Quality Service requirements defined by SLA(Service Level Agreement).
