Abstract:
Wireless sensor networks (WSNs) Holds the potential to improve the efficiency of many systems, for instance, in building automation and process control. Unfortunately, the current technology does not offer guaranteed energy efficiency and reliability for closed-loop stability. The main contribution of this thesis is to provide a modeling, analysis, and design framework for WSN protocols used in control applications. The protocols are designed to minimize the energy consumption of the network which is cost effective, while meeting reliability and delay requirements from the application layer.
In this paper, we have tried to find out the average life time of the batteries calculated for BPSK, QPSK and QAM transmission over different channel models as a function of link distance. Here each modulation is operated at its Optimal SNR. We have also found that, for long transmission distance BPSK,QPSK are optimal choices but as the transmission distance shortens the optimal modulation size grows to 16-QAM even to 64 QAM.
