It is well known that CSMA/CA shows good performance in case of a few devices and low traffic rate but the more the number of devices and traffic rate increase, the more the performance decreases dramatically because of too much contention among the devices. It leads to increasing the retransmission rate it, as a result, brings about high energy consumption and if there are hidden terminal, performance...
We propose an Ethernet ring protection technique introducing a managed forwarding database scheme (FDB). The major benefit of the proposed FDB scheme is provisioning with a cost-optimized path that eliminates an unnecessary overprovision requirement.
Most proposed system objectives such as max-min fairness or proportional fairness are based on the bandwidth of application. However, satisfaction of end users may not be proportional to the bandwidth itself. In this paper, we propose a simple algorithm to achieve so called utility max-min fairness, in which all users can achieve fairness in the application level not in the bandwidth level. Our algorithm...
