چکیده
In wireless and mobile telecommunication systems, the handheld mobile devices completely sustains on lightweight batteries for power supply. This mobile station dissipates lots of energy if it listens to base station continuously for intended messages. This paper presents a discrete time renewal input single and batch service queueing system with accessibility to the batches which is capable of calculating the power efficiency and packet access delay for the power saving type II. A cost model is developed to determine the optimum service rates which minimize the total expected cost. Various performance measures are provided based on this analysis. It is shown numerically that the proposed model can work efficiently to improve the system performance and establish the dependency relationships among the system performance measures and the system parameters.

متن کاملA Clustering Technique of Load-based Power Saving in the IEEE 802.16e Network
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 was discussed in our previous work, and the idea of applying traffic modeling and measurement called Load-Based Power Saving (LBPS) was proposed. The base station in LBPS measures the traffic load and estimates the sleep window size for mobile...

The broadband wireless access (BWA) network, such as IEEE 802.16e, becomes more and more popular in recent years. According to the IEEE 802.16e specifications, mobile subscriber stations (MSSs) with energy constraints are allowed to switch to the sleep mode to reduce their power consumption. Considering a number of service connections on the MSS with different traffic characteristics and reques...
