The Autonomous Decentralized Database System (ADDS) has been proposed to flexibly cope with company's requirements in the dynamically changing environments. In the ADDS, each node can hold the update allowances called AV for countable data items and it is possible to autonomously perform the update operations based on its decision without getting the permissions from other nodes. When the AV shortage happens at one node, it starts the AV adjustment among other nodes in the system and tries to keep balance of total AV amounts in the system. Two types of AV adjustment techniques are considered, that is, Point to Point (P2P) method and mobile agent (MA) method. No discussion has been deployed regarding which method is adequate in what parameters, such as network capacity, node changing frequency in the system, total AV amounts, etc. This paper discusses the adaptability of the both adjustment methods using the developed simulators.
