Abstract
This paper presents a performance improvement by adjusting the transmitted power level of an indoor wireless sensor networks object-locating system. Transmitting high power level of the reference sensor nodes not only result in more coverage areas but also increase an effect from multi-path signals. In order to understand multi-path effect due to transmitting high power level, this research try out on the signal communication between the reference sensor nodes and the sensor nodes that want to be located within the building at different transmitted power levels. The results from the experimental can be applied with the available network planning software to design the location and the power level that the reference sensor nodes could cover an interested area. If the transmitted power level of the reference sensor nodes have been adjusting to the appropriate level, and also cooperate with the specific area constant, then the accuracy of the object-locating system should be increased. |
