Abstract:
In this paper, we evaluate the performance of the CLIR (Cross-Layer Interception and Redirection) cooperative caching scheme for ad hoc networks. Although this caching scheme was developed for Mobile Ad Hoc Networks (MANET) we study the application of this kind of algorithms in static grid ad hoc networks. By means of simulations, we evaluate the mean traffic generated in the wireless network, the delay perceived by the users and the percentage of failed searches as a function of the mean time between requests, the Time To Live (TTL) of the documents, the traffic pattern and the cache sizes. We compare the performance of our proposal with another five cooperative caching schemes as well as the option of no using a caching scheme. The simulation results show that our proposal outperforms the other caching schemes in terms of the studied parameters.
