Optimal range estimation for energy efficient dynamic packet size

Abstract

In this paper energy efficient optimal packet size range is investigated for ad hoc networks. The energy efficiency of optimal packet size depends on a number of factors including channel noise, number of sources and hops, and many physical layer parameters (e.g. path loss, fading, transmitter/receiver power). Therefore, changing the packet size dynamically according to scenarios has been established as a convenient process. However, as there are numbers of parameters involved in size allocation, it is often difficult to fixing the packet size at runtime. Hence, this paper presents an energy efficient optimal packet size range. The observation shows that if that range is retained during the communication process, at least 10%–30% more energy efficiency can be achieved. Efficiency is investigated for time varying scenarios of ad hoc networks using Ns-2 simulator and compared with theoretical estimation. The simulation results matched with the theoretical estimation with low standard deviation.
