Abstract

The application belongs to the field of Internet of Things collaborative computing, and discloses an analysis method and system for accurate cooperation between Internet of Things terminals, which is suitable for Internet of Things scenes such as intelligent agriculture. The method builds an Internet of Things cluster containing high-power and low-power machines, and runs a bidirectional PIM multicast protocol between routers. The system realizes device state synchronization and assisted path pre-construction through an improved IGMP / PIM protocol. When a low-power machine initiates a task request, it can be accurately scheduled to a high-power machine according to the pre-built path. A state-triggered update mechanism is adopted, which only triggers global state revocation when all subordinate devices are busy, greatly reducing network overhead. The system realizes efficient power cooperation between devices, significantly improving task response speed and resource utilization.
