Disruption Tolerant Networks (DTNs) consist of mobile devices that contact each other opportunistically. Propose the original approach to support cooperative caching in DTNs, which enable the sharing and coordination of cached data among multiple nodes and reduces data access delay. The fundamental idea is to intentionally cache data at a set of Network Central Locations (NCLs), which can be easily access by other nodes in the network. Propose an efficient method that ensures appropriate NCL selection based on a probabilistic selection metric and coordinates multiple caching nodes to optimize the tradeoff between data accessibility and caching overhead.
