An analysis on power consumption and link available time of wireless Ad Hoc networks

Abstract

In this thesis, we investigate the distance between two moving nodes that are initially separated and prove that the probability density function of the distance follows the Rician distribution. A simulation result demonstrates excellent agreement with our analytical model. With this distribution, we show that the total average power consumption is proportional to the fourth power for the initial distance of the two nodes and their mean speeds. We also show that the total average power consumption is proportional to the second power of the variance of their speeds. Moreover, we show that the link available time of a singlehop transmission can be improved by employing a multihop transmission. However, most of the improvement comes from the two-hop transmission and the link available time becomes even worse if we introduce more than the two-hop transmission. Finally, we show that in the cellular network, there are advantages of the multihop transmission in terms of both the total average power consumption and link available time.
