On Modeling Single-cell IEEE 802.11 Ad-Hoc Network with Power Saving Mode Conference Paper uri icon

abstract

  • 2015 IEEE. Energy efficiency is a significant aspect in wireless LANs due to the pervasive usage of mobile devices. The most effective way to save energy is turning off the radio, which is the key feature of the IEEE 802.11 power saving mode (PSM) protocol. Understanding the performance such as throughput and energy consumption of 802.11 PSM networks is important because they depend highly on the parameters we choose for contention window size, duty cycling ratio, etc. For this purpose, an analytical model is greatly preferred comparing to the tedious simulation because the former is fast, scalable and can be easily used to optimize performance. This paper presents a comprehensive analytical model for 802.11 IBSS PSM. We derive analytically, using Markov chains, the throughput, total delay and energy consumption, simulate the network using ns-3 simulator, and validate our results through extensive simulations. This model can be conveniently applied to accurately estimate and optimize the performance of single-cell 802.11 PSM ad-hoc networks.
