Resource Allocation for Satellite Communication Network of Emergency Communications in Distribution Network

Extreme disasters will cause significant damage to the conventional communication system of the distribution network, thereby affecting the emergency repair and reconstruction of the distribution network. This paper considers transmitting the distribution network data through satellites to ensure the normal data transmission of the distribution network during disasters. In view of the limited transmission rate between the distribution network equipment and the satellite network, this paper focuses on the resource allocation problem, aiming to increase the amount of data transmitted of the distribution network. Specifically, this paper first models the resource allocation problem as an access-channel joint allocation problem. Then, this paper decomposes the optimization problem into two separate issues: access optimization and channel optimization, which are iteratively solved to derive the resource allocation scheme. Finally, this paper takes a typical satellite system combined with a typical province of China to conduct simulations. The results show that our algorithm can effectively improves the total weighted transmission data.
