Abstract:

A new multi-mode node was designed for the emergency communication with the demand of electricity.The node had the multi-mode communication capability of the private network and the public network technology,which could switch smoothly in three modes:the power private network,the wireless Ad Hoc network and the wireless public network.Data were automatically uploaded to the multi-mode terminal,multi-mode terminal through the mode of rapid switching,with the public network resources to achieve rapid network recovery and continuous transmission of data to achieve off-line emergency communications.Meanwhile,an intelligent routing algorithm based on smoothness was proposed,and the three principles of edge network communication were defined.Through the edge calculation method,the calculation and updating of the smoothness were realized to ensure the intelligent,efficient and reliable operation of the edge network in the offline state.

Key words: power internet of things, edge computing, off-line emergency communication, smoothness
