 Energy Efficient Modulation Techniques for Fault Tolerant Two-Tiered Wireless Sensor NetworksM.Sheik Dawood, Sajin Salim, S Sadasivam and G Athisha Journal of Asian Scientific Research, 2012, vol. 2, issue 3, 124-131 Abstract: A Wireless Sensor Network is composed of hundreds or thousands of nodes that can be equipped with limited energy resources but can still be used over an extensive set of diverse applications such as environment monitoring, healthcare, homeland security, military surveillance, manufacturing, and industry automation. In a safety critical application such as landslide prediction, fault tolerant approaches have to be followed, to ensure the availability of sensor data, at the analysis station, during a critical situation. In this circumstance, we analyze the preeminent modulation scheme, and transmission approach to improve bandwidth and energy efficiency in fault tolerant wireless sensor networks for land slide area monitoring. The total energy consumption includes both the transmission energy and the circuit energy consumption. The modulation schemes are compared based on their energy consumptions at their transceiver node. This paper analyzes the homogenous and heterogeneous modulation schemes to improve the energy efficiency and bandwidth efficiency in a wireless sensor network.
