Energy Efficient Scheduling For Wimax Network

For conserving the power of mobile terminals and to support battery powered mobile broadband wireless access devices efficiently IEEE 802.16e defines a sleep mode operation. By regulating the sleep parameters of the IEEE 802.16e such as starting sleep time, initial sleep window size, minimum sleep interval, maximum sleep interval and listen window size the energy can be efficiently utilized. This project proposes a scheduling scheme that supports the efficient energy usage by regulating the sleep parameters for both the uplink traffic. The base station calculates the sleep parameters for the real time and the non real time traffic by considering the available resources and the traffic rate. By this project both the power saving class I and II sleep efficiency can be regulated by changing the sleep parameters according to the delay constraints and required minimum reserved traffic
