Proposals for packet processing and performance evaluation of IoT devices

In the Internet of Things (IoT), data blocks from a large number of sensors are packetized by IoT devices located at the network's edge and are transferred across networks. Although the transmission capacity and processing power of network equipment have been enhanced recently, packetized schemes should also be optimized, considering that several hundred billion IoT devices will be connected to networks by 2020. This paper proposes packetized schemes for IoT devices that use ZigBee, which is a promising candidate for the implementation of IoT area networks. In the proposed schemes, data blocks from many sensors are aggregated and bundled into a packet. The performance of these schemes is discussed, and their implementation in a prototype system is described to demonstrate their validity.
