Abstract

In this paper, a hybrid cache placement scheme for multihop wireless service networks is proposed. In this scheme, hot nodes in data transferring path are mined up by means of routing navigation graph, and whole network is covered with network clustering scheme. A hot node has been chosen for cache placement in each cluster, and the nodes within a cluster access cache data with no more than two hops. The cache placement scheme reduces data access latency and workload of the server node. It also reduces the average length of data transferring, which means that fewer nodes are involved. The network system energy consumption decreased as involved relay nodes reduced. The performance analysis shows that the scheme achieves significant system performance improvement in network environment, with a large number of nodes.
