Iotbench: A Benchmark Suite for Intelligent Internet of Things Edge Devices

IoT devices must and will be more intelligent in the future. However, due to the lack of benchmarks representative to the diverse IoT applications, there are limited architecture performance studies on IoT devices. This paper presents IoTBench, the first benchmark suite targeting at IoT edge-device applications. This suite includes seven representative programs from three major IoT categories. We investigate the computational demand and execution efficiency of these benchmarks running on a popular IoT device platform. We also analyze and characterize the energy consumption of IoTBench using analytic approaches. Overall, IoTBench establishes a foundation for innovative architecture design of IoT edge devices.
