Abstract

The performance of energy-saving protocols for IEEE 802.11 wireless local area networks was analysed under time-correlated error conditions. Using OPNET, simulations were performed to compare the performance of the infrastructure power saving mode of IEEE 802.11 (PCF-PS) with our proprietary protocol, pointer controlled slot allocation and resynchronisation protocol (PCSAR). The results demonstrate a significant improvement in energy efficiency without significant reduction in performance when using PCSAR. For a wireless network consisting of an access point and 8 power saving stations, energy consumption was up to 28 % lower with PCSAR compared to PCF-PS. The results also show that PCSAR offers significantly reduced uplink access delay over PCF-PS, while modestly improving uplink throughput.
