Wireless sensor networks have attracted a lot of interest by various industries for its ability to perform real time measurements in a cost effective way.
Since the sensor nodes often rely on batteries to perform their task, a lot of research have been focused on minimizing the energy consumption in WSN.
In this project TDMA based WSN was investigated to see if the energy consumption could be minimized by manipulating the nodes communication range.
Though a lot of research has been focused on similar problems exist these are mostly focused on non TDMA network.
The problem was partially analysed analytically, but the mainly assessed by simulation, using the OMNeT++ simulation framework. Since OMNeT++ is not a simulator by it self, the MiXiM model framework that focuses on the simulation of wireless networks was used.
It was shown that a minimum point for energy consumption can be found. However, a small degradation in the quality of the links may cause a dramatic increase in the energy consumption due to retransmissions.
