Drones have demonstrate their potential in a wide range of application scenarios such as cargo delivery, policing operations, power line and pipeline inspections, agriculture and emergency communications. However, when a large number of drones fly in the sky, how to ensure the safety of unmanned individuals becomes especially important. 

In recent year, the concept of V2X is proposed based on the vehicle communication V2V. V2X mainly focuses on the communication between the driving vehicles and other entities. However, one single method of communication and data processing cannot meet the all the requirements of V2X. A merged architecture of heterogeneous networks and a hierarchical computing mode are needed.

NB-IoT is proposed by 3GPP based on LTE, to fulfill the demand from IoT scenarios. NB-IoT has multiple advantages, including high capacity, low communication overhead, enhanced coverage, long life span and low price. NB-IoT networks are built in many countries to serve many applications, like shared bikes.

Inter-network interconnection and integration are the necessities to popularize Internet of Things (IoT). However, research about other heterogeneous networks cannot be applied in integrating heterogeneous IoT networks, due to the significant different between IoT networks and other types of networks. 

Message Queuing Telemetry Transport (MQTT) fits for low-transmission-rate Internet of Things (IoT) system due to its lightweight. An IoT system is developed for typical scenarios, which enables IoT devices to exchange data, and enables users to manage the whole system, e.g. users can check each device’s transmission-condition, and modify devices’ configuration. 

To solve the series of problems induced by new energy devices in grid, we propose a tight-coupled cyber-physical system to coordinate new energy devices so that the grid functions normally and grid resource is maximally and equally utilized.
