A Probabilistic and Rebalancing Cache Placement Strategy for ICN in MANETs

Cache placement is a key component of information centric networking (ICN) for optimizing network performance. Previews works on caching placement mainly focus on fixed or semi fixed network. We propose a cache placement/update strategy in a mobile ad hoc network (MANET) environment where content consumer and provider are constantly mobile. Based on hotspot recognition and user requirement modeling, two approaches named Pcaching and Cache Rebalancing are proposed to settle the cache placement/update problem in one region and between different regions. We evaluate the performance of our approach compared with existing caching scheme and show that Pcaching has its advantage in both hit ratio and hop count over previews strategy.
