We present a scheme, called global cluster cooperation (GCC) for caching in mobile ad hoc networks where network topology is partitioned into non-overlapping clusters based on the physical network proximity. In this scheme cluster cache state (CCS), which is the information regarding the contents of all the mobile nodes (MNs) within a cluster, is maintained at each node. In case of cluster cache miss, we propose to keep global cache state (GCS) at a node called cluster state node (CSN). Simulation experiments show that the GCC caching mechanism achieves significant improvements in average query latency and reduces the cache management overheads in comparison with other caching strategies.
