Considering that the traffic characteristics of certain applications feature small-data patterns especially in typical IoT control scenarios such as robot control on the downlink. Aggregation data delivery system has good performance in handling multi-source, multi-destination, and massive small-data delivery with characteristics of low-overhead, high-throughput, and ultra-low-latency for a resource-constrained wireless transmission system. In order to rapidly deliver multiple small-data to multiple receivers efficiently, based on P4 switches, we attempt to develop a novel arithmetic aggregation coding scheme based on RNS, which would meet the need to aggregately encode multiple small-data messages, as an indispensable complementary component to the resource-constrained wireless transmission system.
