Causally Ordered Message Delivery Protocol for Mobile Agent Group Considering Reliability

Abstract
A swarm of mobile agents may be used as a vital medium for dynamically collaborative distributed applications based on unreliable networks requiring reliable causally ordered message delivery. However, the existing message delivery protocols for mobile agent groups may not satisfy this important requirement. In this paper, we propose a new causally ordered mobile agent group communication protocol to achieve all the requirements mentioned above as follows. First, to guarantee agent communication reliability to a maximum despite agent location managers' failures, the location information of each agent can be replicated in an effective way to degrade its scalability to a minimum despite agent mobility. Second, it guarantees all messages sent to a mobile agent group to be reliably delivered to its surviving group members in a consistent causal order.
