With the rapid development of Internet and wireless communication technology, ubiquitous network services become more and more popular. WiMAX is widely used to solve the last mile in network deployment. To enhance the mobility, mobile WiMAX is launched to support the mobile usages. Due to the limited power of mobile devices, power saving becomes a key issue for mobile WiMAX applications. Though plenty of efforts have been proposed to save power on the mobile devices, the problems are partially solved. Among others, sleep mode operations are widely adopted to save power in wireless communications. Generally, longer sleep time can reduce power consumption at the cost of increased packet response delay. To improve the quality of services, an adaptive power saving scheme for mobile WiMAX is proposed in this paper. Parameters related to power management are dynamically set according to current network traffic load. The analyses and simulation results show that the proposed scheme presents superior power efficiency and packet response delay in the context of mobile WiMAX.
