%X Cooperative caching has been adequately addressed in MANETs for QoS and cooperative computing. This paper presents a Cluster-based Consistency Scheme,CCS.In CCS,the close nodes in locality are organized into a cluster,where a more stable and powerful node is selected as header in each cluster and the others are at most 2 hops away from the header as the members of the cluster.All header nodes form a ring with Chord as group management protocol.An updating tree is built dynamically on top of the Chord ring to propagate the updated data items.In this way,the updated data item is broadcasted within cluster at MAC layer and transmitted among the header nodes along the updating tree.The simulation results demonstrate CCS outperforms the Gossip scheme for consistency of cooperative caching with less workload,higher success rate and less updating time.
