Classification of Packet Transmission Outcomes in Wireless Sensor Networks

In wireless networks, it is important to determine the outcome of packet transmissions for networking protocols. In this paper, the authors design a transmission outcome classifier for wireless sensor networks based on received signal strength indicator and link quality indicator values. Their classifier performs loss differentiation by analyzing statistical differences between weak signal and collision losses. They implement their proposed classifier using the CC2500 RF transceiver and evaluate it experimentally. The results show that their classifier can accurately detect packet transmissions as well as distinguish wireless losses due to weak signals and multiple access collisions, with a maximum error rate of 15%.
