| Research Abstract |
Computer networks are suffered from all kinds of failures. When a packet fails in transmission, it has to be retransmitted. In order to cope with failures such as packet transmission, route selection, we need to prepare extra network resources for keeping network alive. Network resilience can be obtained when network provides enough resources for traffic flows depending on users demands. In this research, we have investigated the method to estimate network resources for resilient networks. Architecture for long-life information networks has been investigated from the view points of energy saving, resilience against node and link failures in wireless networks.
