Title
An efficient power saving mechanism for sleep mode in IEEE 802.16e networks
Abstract
In order to reduce the power consumption to extend the lifetime of battery-powered Mobile Stations (MSs), IEEE 802.16e has introduced a sleep mode to decrease the usage of air interface resources of serving Base Stations (BSs). In the sleep mode, MS enters into a sleep cycle after negotiating with serving BS and stops its traffic service temporarily. In order to reduce the energy consumption as well as decrease the packet delay especially in low traffic scenario, this paper proposes a novel power saving algorithm for sleep mode in which the sleep interval is increased in power function each time until a maximum sleep interval threshold is reached. Theoretical analysis and simulation experiments demonstrate that the proposed algorithm can achieve significantly less mean energy consumption and mean response time compared with exponential and linear increase algorithms. Furthermore, this paper analyzes the performance impact of each parameter in the algorithm and presents how to configure the sleep mode parameters.
