Different techniques for measuring packet delivery ratio, packet latency and power usage on single hop radio links have been developed. These techniques were tested with Zolertia Z1 motes running Contiki by measuring the performances of different radio duty cycling protocols using a range of radio wake-up rates and various levels of global radio traffic.(More)
During experimental evaluations of RPL on a network with some 20 Zolertia Z1 motes running Contiki version 2.6, inconsistent Packet Delivery Ratios (PDR) and message latencies were frequently observed. Replacing ContikiMAC by NullRDC brought consistency, proving that the problem had to be found in the Radio Duty Cyling (RDC) protocol. Two implementation(More)
