PowerMannaSim: An extension with power consumption modeling to MannaSim, a Wireless Sensor Network module of NS-2

MannaSim is an extension to the consecrated network simulation tool NS-2, to simulate Wireless Sensor Networks (WSN). However, MannaSim's power consumption module can be improved to include some influential factors in a WSN. The objective of this work is to present PowerMannaSim. This extension provides two important features for the simulation of energy consumption in a WSN. The first one is an estimating model for the number of clock cycles spent in a code that runs on the sensor node. The second is a realistic energy decay model of the sensor node's batteries, which is based on the discharge rate of the battery and considers factors such as the environment's temperature in which the sensor node is.
