Data Distribution in IoT Networks with Estimation of Packet Error Rate

摘要

Internet of Things (IoT) is a network of things with wireless networks for connecting things and people on a massive scale. Energy harvesting from a surrounding environment is one of the key techniques to achieve a sustainable IoT network. In an IoT environment, reliable broadcast plays an important role to distribute data to a large number of surrounding devices. Forward Error Correction (FEC) enables a receiver to detect and correct errors for a received packet. The fountain code, which is a type of FEC, is suitable for IoT environment due to its high scalability and low complexity. When the FEC is applied to a data broadcast scenario in IoT networks, fast and reliable broadcast can be achieved. In this paper, we propose a new broadcast method to utilize a moving average to estimate a packet error rate of the current frame in the environment with a large number of connected devices. This proposed scheme is desirable to achieve high data restoration probability by obtaining a proper number of output packets.
