Power Management and Rate Control Mechanism for Wi-Fi Infrastructure Networks

The advances in wireless networks have encouraged the use of mobile devices in everyday life. However, one of the main problems of these devices is the limited amount of energy they have available to use in order to function and the extended energy consumption of wireless adapters. A lot of research has been done to reduce the amount of energy spent on wireless communications. On the other hand, the extended use of wireless networks causes interference problems in communications, which affect the overall performance of each network. The purpose of this work is to provide a mechanism, which can reduce the power consumption on the station side and increase the mobile devices´ operation time, and in combination with a rate adaptation mechanism on the access point side, improve the overall performance of the network.
