N2 - In this paper, a joint content packets placement and scheduling optimization problem is investigated to minimize the in put/output (I/O) latency of wireless content caching networks (WCCNs), taking into account the real content coding mode, namely, repetition coding, and successful retrieving criterion in practical systems. The formulated non-convex integer programming problem is optimally solved by a one-dimension search-based algorithm with feasibility checking through equivalent problem transformation. We also analyze the time complexity of the designed solution. Extensive numerical simulation results reveal that the proposed joint optimization algorithm outperforms the baseline scheme significantly in terms of I/O latency as well as outage performance.
