Unselfish Cooperative Game-Based Communication Optimization of ECG Monitoring Network

Abstract

With the increasing incidence rate of cardiovascular diseases, the prevention and treatment of heart disease has been highly concerned. people have developed a variety of real-time ECG monitoring systems, and some even built a wireless sensor network (WSN) suitable for ECG monitoring to early detect and treat heart disease in time. ECG monitoring network is a special kind of wireless body area network based on IEEE802.15.4 communication protocol. To study the communication technology of ECG monitoring network is of great importance. The communication mechanism and data frame structure are analyzed, and the node energy efficiency model and transmission delay model are established; A unselfish cooperative game algorithm combined with light and low profit operator is proposed to overcome the conflict between energy consumption and time delay and realize the balance between them. Experiments showed that the proposed algorithm could effectively reach equilibrium of the two targets. Moreover, compared with Multi-objective Evolutionary Algorithm and Evolutionary cooperative game Algorithm, it had better performance in convergence speed and global convergence.
