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.
