| Outline of Final Research Achievements |
In this study, we aimed to achieve low energy, low latency and high throughput for high density networks consisting of many heterogeneous wireless sensor nodes; then tackled to develop 1) topology control and its configuration, 2) interference-tolerant access control, and 3) a full-duplexed backbone network.We obtained mainly the following results. 1) In a clustered network using CSMA, it is important to consider the number of clusters and the carrier sense threshold. In a virtual full-duplex network, there are optimal values for the placement of cluster heads and the transmit power. 2) In the presence of interference from other cells, power control based on the success or failure of reception is effective. 3) A high-performance self-interference canceller is developed, and the BlockACK is effective in multi-hop communication.
