Abstract


Caching in wireless networks means where the nodes may be mobile and exchange information in a peer-to-peer method with large and small-sized caches. For large-sized caches, devise a strategy where nodes, independent of each other, decide whether to cache some content and for how long and small-sized caches, aim to design a content replacement strategy that allows nodes to successfully store newly received information while maintaining the good performance of the content distribution system. Under these conditions, each node takes decisions according to its perception of what nearby users may store in their caches and with the aim of differentiating its own cache content from the other nodes’. Our system propose a novel asymmetric cooperative cache approach, where the data requests are transmitted to the cache layer on every node, but the data replies are only transmitted to the cache layer at the intermediate nodes that need to cache the data. This solution not only reduces the overhead of copying data between the user space and the kernel space, it also allows data pipelines to reduce the end-to-end delay. Another objective of this project is to propose OLSR and DSR algorithm for the novel asymmetric cooperative cache approach and to evaluate the two proposed routing protocols namely, OLSR and DSR, for wireless ad-hoc networks based on performance and compare them with other caching schemes, showing that our analysis succeeds in creating the desired content diversity, thus leading to a resource-efficient information access.
