Summary:
In wireless multi-hop networks, content servers are generally located outside a wireless multi-hop network and a user accesses these servers through a gateway node. So, content traffic has a tendency to be concentrated at a gateway node, which might cause throughput degradation in a whole wireless multi-hop network. Caching network is one promising way to resolve this technical problem. However, caching network has a limitation of cache availability on a default-path. For wired networks, Breadcrumbs has been proposed as in-network guide for cached contents. In this paper, we evaluate Breadcrumbs in wireless multi-hop networks. Our simulation results show that Breadcrumbs improves total throughput performance of wireless multi-hop networks. And also they surprisingly show that not only popular content throughput but also unpopular content throughput is improved.
