| Summary: | Abstract Cache placement is an integral part of information centric networking (ICN) for optimizing the performance of network. The majority of the existing research on cache placement explores fixed or semi fixed network. The present study proposed a cache placement/update policy in a mobile ad-hoc network (MANET) environment, where the consumers and providers of information are constantly moving. On the basis of request probability and transition probability analysis, a novel approach called cache rebalancing is projected to deal with the cache placement/update problem between different regions. Besides, this study also assesses the performance of the proposed approach in comparison with current caching scheme in large-scale real urban mobility traces, demonstrating that our approach are advantageous in hit ratio, hop count, and other performance indexes over previous strategy. Moreover, the cache steady state of our approach is also obtained to demonstrate the request probability in any region.
