Abstract

We anticipate digital social innovation for improving our life and society. Internet of Things (IoT) is now considered as a key driving force for achieving such next generation social systems. Several approaches have been proposed to achieve effective IoT communications, where each device has very limited communication capabilities. One such approach is the introduction of short packets for a lightweight communication protocol by which we can form a local area sensor network dedicated to IoT devices and can achieve effective packet processing, reducing power consumption, and minimizing bandwidth occupancy. The short packet can solve prob-lems regarding local networks, but creates another problem for the wide area Internet, where various devices and local networks are converged. We propose an aggregation scheme that makes it possible to reduce power consumption and packet processing loads caused by a huge amount of short packets. We especially focus on the wide area Internet with our proposed scheme to support IoT traffic more efficiently by showing our CoAP-based implementation.
