ABSTRACT

The development of technology in the wireless communication domain has enhanced the need for power optimization schemes, because the battery technology has not kept up pace with the ever increasing growth of mobile devices. Power consumption can be reduced by decreasing the transmit power to a minimal optimum level, such that the packets are received correctly. This paper compares IEEE 802.11b and IEEE 802.11n wireless networks and shows that optimization of power control, increases the life of the battery and maybe achieved by the implementation of IEEE 802.11n. The paper studies the power consumption as against the transmit power and also shows the effect of co-channel interference. Elements of network performance include throughput, delay, bandwidth and channel utilization. The result compares IEEE802.11n with IEEE802.11b in terms of power consumption. The results show an improvement in performance of the wireless network using IEEE 802.11n.
