Impact of Channel Capacity and Signal Bandwidth on Power Consumption in New Generation Wireless Networks

Abstract:-Nowadays, wireless communication has become an important aspect in almost every sphere of life. As wireless devices are battery-constrained, energy competency is an important issue in analyzing the performance of wireless networks. With the advent of Green Networking, energy efficient mechanisms are need of hour. Channel capacity and signal bandwidth are two of the important factors that can affect the energy levels of the wireless devices especially during handover. This paper presented the effect of channel capacity and signal bandwidth on power consumption of wireless devices during vertical handoff. Handover simulation between Wi-Fi and WiMAX technology was implemented for two sets of nodes namely Type-I and Type-II nodes. Evaluation of power consumption was made at three different voltage levels i.e. charge voltage, nominal voltage and cut-off voltage. The performance of network was measured in terms of throughput, Packet Delivery Ratio and residual energy levels of the nodes. The results of the study can provide a roadmap to the novel researchers for devising energy efficient handoff mechanisms to enhance the performance of wireless networks.
