| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The network load is increasing due to the spread of content distribution services. Caching is known as a technique to reduce network load by prefetching popular content into memories at users. Coded caching is a new caching approach based on a carefully designed content placement in order to create coded multicasting opportunities. The coded caching schemes in single-rate networks are evaluated by the trade-off between memory size and delivery data size. Considering the network with multiple transmission rates, it is important how to operate multicast, which needs to use the smallest rate among users. In multi-rate wireless networks, multicast scheduling schemes are evaluated by throughput and delay. We have already proposed the coded caching scheme for multi-rate wireless networks and have evaluated by the throughput and delay. However, coded caching schemes can not be correctly evaluated because the throughput has drawbacks. In this paper, we redefined the throughput for evaluating the coded caching scheme and evaluate our coded caching scheme by comparison with the conventional schemes. |
