We explore the use of caching both at the network edge and within User Equipment(UE)to alleviate traffic load of wireless networks.We develop a joint cache placement and delivery policy that maximizes the Quality of S...
I consider a system whose deterioration follows a discrete-time and discrete-state Markov chain with an absorbing state. When the system is put into practice, I may select operation (wait), imperfect repair, or replac...
Data analytics of an information system is conducted based on a Markov decision process(MDP)and a partially observable Markov decision process(POMDP)in this paper.Data analytics over a finite planning horizon and an i...
