Performance Comparison Based-RSSI for Sensor Networks in Different Environments

A lot of the wireless sensor network applications call for sensor nodes to be applicable to any environment. RSSI-based measurements implement conveniently and are cost-efficient and power-efficient in practice. This paper compares the distance estimation performances based RSSI in three different environments by experiments and discusses their characteristic in detail. We carry out a large amount of repeated experiment based on RSSI in three kinds of environments over the 2.4GHz wireless channel. Subsequently, we focus on studying and discussing data analyses of RSSI and possible improvements in each environment. Experimental results demonstrate availability and feasibility of RSSI in outdoor and indoor environments.
