| Outline of Final Research Achievements |
Encoding data at all nodes in a network can maximize data transmission efficiency. Encoding consumes processing power of routers, however. In this research, we investigated the placement of encoding nodes in a part of network nodes and data transmission strategies in such a network while achieving the comparable data transmission efficiency to the one in encoding at every node. We first identified that the reason of data-transfer efficiency improvement resides in the redundancy which help us to avoid duplicated data transmission. We also proposed a encoding-node placement algorithms exploiting indices that expresses features of network topologies and succeeded in improving data transmission efficiency effectively.
