Executive Summary

Previous works in IEEE 802.16e power saving mainly focused on standard Type I or Type II. The limitation of adopting Type I or Type II is discussed in the paper, and the idea of applying traffic modeling and measurement mechanisms called Load-Based Power Saving (LBPS) is proposed. The base station in LBPS measures the traffic load and estimates the sleep window size for mobile subscriber stations by setting a threshold for data accumulation. A basic version of LBPS, LBPS-Aggr, is presented in the paper. Simulation results demonstrate that better power saving efficiency can be achieved by LBPS-Aggr than Type I and Type II.
