An Algorithm of Cache Preloading in Cooperative Caching Based on Ad Hoc Network

Because of the feature of Ad Hoc network, the cooperating among mobile nodes is very important. The most common cooperating mechanism among mobile nodes is cooperative caching. That is, mobile nodes caching some important data or other resources, which can be used by other mobile nodes. Cooperative caching play a very important role in traditional networks for data access and information distribution and it will be very important in wireless Ad Hoc networks. In this paper, an algorithm of cache preloading in AD HOC environment are given. Simulation experiments demonstrate that the data request delay in Ad Hoc network can be reduced and the network performance can be improved, with the using of cache preloading algorithm given in this paper to select the data in cache.
