LBPS: Load-Based Power Saving in the IEEE 802.16e Network q,qq,qqq
TLDR
Simulation results demonstrate that better power saving efficiency can be achieved by proposed LBPS schemes than standard Type I and Type II.Abstract:
Previous works in IEEE 802.16e power saving mainly focused on standard Type I or Type II power saving class. The limitation of adopting Type I or Type II is discussed in the paper, and the idea of 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, in which all of the traffic in the network is treated as a single aggregate flow in estimation of the sleep window size. Adopting the idea of group splitting or merging in sleep schedule, two enhanced versions namely LBPS-Split and LBPS-Merge are proposed. Simulation results demonstrate that better power saving efficiency can be achieved by proread more

The Power-Saving Mechanism With Periodic Traffic Indications in the IEEE 802.16e/m
TL;DR: A new sleep mode scheme with periodic traffic indications, where the MOB-SLP-REQ/RSP messages are omitted, and a traffic indication is periodically sent at the beginning of every constant TRF-IND interval, which minimizes the average power consumption of the MS while satisfying the quality of service (QoS) on the mean delay.
