Network Group

With the recent rapid development of smart appliances, home networking technology becomes to attract public attention. This group researches on home network platform.

Home Networking Platform

The home network is built easily with wireless communication standard, such as IEEE802.11 or IEEE802.15.4, which utilizes ISM band. However the throughput becomes low since a channel in ISM band is shared with many nodes by using Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA).

Cognitive radio is a very promising technique to solve such a problem. In such a cognitive radio system, each wireless node changes transmission parameters according to communication environment surrounding the node.

We are studying about home network platform which has the capability of both "environment cognition" such as location estimation of wireless nodes or carrier sensing and "adaptive operation" such as dynamic selection of spectra according to result of environment cognition.
