Agent-Dependent Modeling (ABM) is actually a sort of simulation that designs devices as a group of brokers. An agent is a person entity throughout the program that has its individual set of attributes and behaviors. These agents communicate with each other and their environment, and their actions may result in complex, emergent behaviors with the procedure level.
