The abilities of in-network caching in Named Data Networking (NDN) agrees to enable effective data dissemination throughout the globe without requiring the end-to-end communication infrastructure. The goal of this study is to develop an efficient content placement strategy for the NDN caching module to achieve the enhanced performance for the NDN network. In this work, optimizations of the problems in NDN-based caching strategies are formulated and to solve these problems, a new caching strategy is designed Named as Efficient Hybrid Content Placement (EHCP). The aim of the EHPC strategy is to reduce the multiple replications of homogeneous contents at numerous locations during data dissemination and to increase the diverse number of contents along the data delivery path. In addition, the effect of the cache-hit ratio, hop-decrement, and content redundancy is shown by comparing the proposed caching strategy with other state-of-the-art caching strategies in a simulation environment. The consequences show that the proposed strategy delivers an enhanced number of heterogeneous contents in terms of improving content diversity ratio along with the higher cache-hit ratio. Moreover, with different cache sizes, EHCP performs better in terms of content redundancy and hop-decrement as compared to the existing state-of-the-art strategies.
