Rapid progress in MicroElectroMechanical System (MEMS) and Radio Frequency (RF) design has enabled the development of low-power, inexpensive, and network-enabled microsensors. These sensor nodes are capable of capturing various physical information, such as temperature, pressure, motion of an object, etc as well as mapping such physical characteristics of the environment to quantitative measurements. A typical Wireless Sensor Network (WSN) consists of hundreds to thousands of such sensor nodes linked by a wireless medium. In this paper, the authors present a comparative investigation of energy consumption for few commercially available chipsets such as TR1001, CC1000 and CC1010 based on different scheduling methods for two types of deployment strategies. They conducted the experiment within the OMNeT++ simulator.
