System(s) and method(s) for real-time data communication over an Internet of Things (IoT) network are described. According to the present subject matter, the system(s) implement the described method(s) for real-time data communication over the IoT network. The method includes encoding, at a source communication device, data to be exchanged between peer sub-layers of IoT entities based on a Forward Error Correction (FEC) context to generate encoded data packets, the IoT entities comprising the source communication device and a destination communication device. The method further includes identifying time delay to be maintained for transmission of the encoded data packets from the source communication device to the destination communication device to have minimal data packet drop due to queue overflow at the source communication device. The method further includes transmitting the encoded data packets over the IoT network.
