Abstract

In this paper, the performance improvement of a Mobile Ad Hoc Network that implements a caching technique based on the redirection of the requests is evaluated. The redirection technique is implemented over a cooperative caching scheme that utilizes both local and redirection caching strategies. For this purpose, the proposed scheme stores information about the location of the documents in the wireless network analyzing the forwarded request and reply messages. By using this information, the documents requests can be redirected to mobile nodes that are known to be closer than the final data server. By means of simulations, the redirection technique is shown to improve the efficiency of the caching process.
