Rapid progress in microelectromechanical system (MEMS) and radio frequency(RF) design has enabled the development of low-power, inexpensive, andnetwork-enabled microsensors. These sensor nodes are capable of capturingvarious physical information, such as temperature, pressure, motion of anobject, etc as well as mapping such physical characteristics of the environmentto quantitative measurements. A typical wireless sensor network (WSN) consistsof hundreds to thousands of such sensor nodes linked by a wireless medium. Inthis paper, we present a comparative investigation of energy consumption forfew commercially available chipsets such as TR1001, CC1000 and CC1010 based ondifferent scheduling methods for two types of deployment strategies. Weconducted our experiment within the OMNeT++ simulator.
