Aimed at the problem of high processing delay and low quality of services of cloud computing in individual soldier combat system, a distributed individual soldier combat information system supported by wearable technology was proposed. A local computing layer was constructed by using the intelligent equipment of the soldier, which can provide a platform for battlefield data processing at the nearest combat place and supply soldier with the ability of information fusion and processing. The generalized diffusion load balancing algorithm was used to balance the load of equipment for reducing the delay of business processing and the reliability of the system was enhanced by the distributed computing in realistic battlefield environment. The simulation results show that the distributed wearable local network architecture can effectively reduce the processing delay and enhance the reliability of the combat system.
