Opportunistic Distributed Caching for Mission-Oriented Delay-Tolerant Networks
In this paper, a new caching scheme has been proposed which takes into consideration mission-oriented applications of Delay-tolerant Networks (DTNs) such as in Military. In such applications data need to be cached following different criteria and priority levels. In these applications, other than data popularity based on request frequency, the importance is also given to who created and ranked POIs (point of interest) in the data (images), when and where it was created; higher rank data belonging to some specific location may be more important though the frequency of those may not be higher than frequency based popular data. Thus, our caching scheme for DTNs is designed by taking different requirements into consideration for defense applications so that access latency for higher priority but lesser accessed data is reduced. The performance evaluation shows that our caching scheme based on criteria other than popularity reduces the overall access latency, cache miss and cache memory when compared to other caching schemes.
